this regulation are to be observed in the interests of safe and correct welding operation.
* Available from the trade association responsible or
Carl Heymanns-Verlag, Luxemburger Strasse 449, 50939 Cologne.
2.1
Safety instructions
This unit is manufactured according to the requirements and stipulations of EN 60974.1 / VDE
0544 part 1. BGV D1 (earlier VBG 15) of the trade association for precision engineering and
electrical engineering are as well valid.
1) In case of an accident, the cutting unit must be disconnected from the mains
immediately.
2) If electrical contact voltages arise, switch off the unit immediately, disconnect it from
the mains and proceed to inspection by a qualified electrician or by our Service
Department.
3) Before opening the unit, disconnect it from the mains supply.
4) Repair work may only be carried out by a skilled electrician or by our Service
Department.
5) Before the unit is put to operation, check it visually, as well as the torch and all cables

DIN EN 169.
During the work, the welder’s body must be completely protected against radiation and
burns by means of protective clothing and face protection. Long gloves, aprons and
welding shields with welding filters conforming to DIN EN 470-1 and BGR 189
must be worn.
Synthetic clothing are excluded. Shoes must be closed, not opened (due to spatters). If
necessary, protective headwear must be worn (e.g. for overhead welding). If cover
glasses are used, these must be in accordance with the norms specified above.
As additional protection for the eyes against UV radiation, safety goggles with side
shields and corresponding face protection in accordance with BGR 192 and BGI 553
must be worn.
Accident prevention regulation BGV D1 § 27 stipulates that it is the responsibility of the
employer to provide suitable personal protective equipment, while § 28 stipulates that it
is the responsibility of the insured to wear suitable clothing.
3
7) Protection when welding under increased electrical risks
Welding rectifiers and welding power sources which can optionally be used for either
direct or alternating current must be marked "S" in accordance with EN 60974-1 and
BGI 534.
Use insulating materials to protect you against contact with electrically conductive parts
and damp floors. Wear dry, undamaged work clothing, long gloves and footwear with
rubber soles. Ventilate rooms, install extraction systems if required, and wear respiratory
protective equipment if necessary (see Procedural instructions BGV D1 § 27 and BGI 533,
Section 5).
8) In order to prevent stray currents and the effects thereof (e.g. destruction of electrical
protective ground conductors), the welding return cable (workpiece cable) must be
connected directly to the workpiece to be welded or to the table (e.g. welding table, gridtype welding table, workbench) supporting the workpiece (see BGV D1 § 20). When
installing the ground connection, assure that there is a good electrical contact (remove
rust, paint, etc.).
9) During welding pauses, the welding torch is to be laid down on an insulated surface or
hung up in such a way that it is not in contact with the workpiece and its support
connected to the welding power source (see § 20 BGV D1).
In the case of longer work pauses, the welding unit must be switched off and the gas
cylinder valve must be closed.
10) The shielding gas cylinder must always be protected against tumbling downing using a
safety chain.
11) Under no circumstances the unit may be put into operation while it is opened
(e.g. for repair work). Apart from the safety regulations, sufficient cooling of the
electrical components provided by the fan cannot be guaranteed.
12) In accordance with BGV D1 § 5, people in the vicinity of the arc must also be informed
of the hazards and protected against them. Safety partitions (“welding safety curtains”)
must be erected in accordance with DIN EN 1598.
14) No welding work may be carried out on containers in which gases, fuels, mineral oils or
similar substances have been stored Öeven if they have been empty for a long timeÕ
(risk of explosion). See § 31 of accident prevention regulation BGV D1.
15) Welds which will be subjected to high loads and which need to meet specific safety
requirements may only be carried out by specially trained and qualified welders.
15) Never bring the torch close to your face.
16) In areas at particularly high risk of fire, the welder must obtain a welding permit and
have this on his person throughout the duration of the welding work. On completion of
welding, a fire-guard must be delegated to ensure fire protection.
17) Ventilation measures must be applied in accordance with BGI 553, Section 9.
18) The hazard to eyesight must be indicated by means of a sign at the work site "CAUTION!
Do not look into the arc!".

Duty cycle
The duty cylce measurings have been carried out in accordance with
EN 60974-1 / VDE 0544 part 1 (10 min working period).
60% duty cycle means:
After a 6 min. welding period a 4 min welding pause must be respected. The electrical
components are thermally protected against overheating.

Instructions to avoid interferences due to electromagnetic influences EMC
The welding unit has been manufactured in accordance with the requirements of guideline
EN 60974-10 / VDE 0544-part 10 regarding electromagnetic compatibility. It is nonetheless the
responsibility of the user to ensure that the welding equipment is installed and operated in
accordance with the manufacturer’s instructions. If electromagnetic interference is detected, it
is the responsibility of the user of the welding equipment to find a solution with the technical
assistance of the manufacturer. In some cases, it may be sufficient simply to ground the welding
current circuit. In other cases, it may be necessary to build a complete shield for the welding
power source and workpiece using the input filters. In all cases, electromagnetic interference
must be reduced to avoid any possible malfunctions.
Note: For safety reasons, the welding current circuit may or may not be grounded. No
modifications may be made to the grounding without the approval of an expert who is able to
determine whether the changes might increase the risk of accidents, e.g. by allowing parallel
welding current return paths which could destroy the ground conductors of other equipment.
Further instructions are contained in TEC 974-XX "Arc welding equipment – installation and
use".

Evaluation of the installation site
Before installing the welding equipment, the user must evaluate potential
electromagnetic problems in the vicinity. The following must be taken into
consideration:
Other power cables, control cables, signal and telecommunication cables above, below
and next to the welding equipment
Radio and television transmitters and receivers
Computers and other control devices
The health of people in the vicinity, e.g. use of heart pacemaker and hearing aids
Calibration and measuring equipment
Interference immunity of other devices in the vicinity. The user must ensure the
electromagnetic compatibility of other devices used in the vicinity. This may require
additional safety measures.
Procedures to reduce emitted interference
Mains supply
Welding equipment is to be connected to the mains in compliance with the
recommendations of the manufacturer. If interference occurs, it may be necessary to
take additional precautions, e.g. filters for the mains connection. Make sure that the
power cable of welding equipment is installed in a fixed position shielded by means of a
metal conduit or similar. The entire length of the shield must be electrically connected.
The shield must be connected to the welding power source in the way to obtain a good
electrical contact between the metal conduit and the housing of the welding unit.

6)
Maintenance of the welding equipment
Welding equipment must be maintained regularly in accordance with the
recommendations of the manufacturer. All access and service doors and covers must be
closed and fastened securely when the welding equipment is in operation. No
modifications whatsoever may be made to welding equipment with the exception of
modifications and adjustments specified in the manufacturer’s operating instructions.
Welding cables
Welding cables should be kept as short as possible and routed close together on or near
the floor.
Equipotential bonding
It is advisable to interconnect all metallic parts in and next to the welding equipment.
Metallic parts connected to the workpiece can, however, increase the risk of the welder
receiving an electric shock by touching these metallic parts and the electrode
simultaneously. The welder must be electrically insulated against all these connected
metallic parts.
Grounding the workpiece
If the workpiece is not connected to the ground for electrical safety reasons, or due to
the size and position of the workpiece, e.g. steel structure or outer wall of a ship,
grounding the workpiece may in some cases, but not all, reduce emitted interference. It
must be ensured that grounding the workpiece will not increase the risk of accidents for
the user and cannot cause the destruction of other electrical equipment. If necessary,
the grounding of the workpiece must be carried out by means of a direct connection to
the workpiece. In countries where a direct connection is prohibited, the connection must
be made by means of suitable reactors, selected in accordance with national regulations.
Shielding
Selective shielding of other cables and devices in the vicinity can reduce interference
problems. For special applications, it may be worth considering shielding the entire
welding system.

or if the water pump has activated.
7.3
Choosing a Process
Using rotary switch 5 the user can select between the MIG/MAG, Pulse Arc, Interpuls, MMA or TIG
welding processes.
MIG/MAG- und Pulse-Arc Welding Programs
Rotary switch 5 must be switched to either the MIG/MAG or Pulse position. The desired welding
program may now be selected in conjunction with Rotary switch 6 and the use of the Multi Function
Display (MFD 19). Turning Rotary switch 6 through a clockwise direction will enable the following Main
Menus:
Material
New Job
Throat thickness
Impedance (MIG/MAG) or Pulse form (Pulse)
In the Main Menu select Material, by pressing the Rotary switch (6) once a secondary menu listing all
materials will appear, by turning switch 6 and pressing on the desired material that material is selected
and the next Menu field is activated. The next Menu field is titled Filler wire size, by turning and
pressing Rotary switch 6 the desired filler wire size can be selected. The final sub menu to appear is
titled Gas, again through turning and pressing Rotary switch 6 the desired gas can be selected from the
list. By pressing switch 6 one last time the menu table is exited and the chosen program is activated and
ready for use.
Using Dial (1) the desired welding current may be selected, with Dial (2) the Arc-Length (Arc Trim) can be
individually adjusted for each job. If the user wishes to use the wire feed unit to select the desired
current and arc length (switches 25, 26), then the symbol for the Wire feed unit must be selected using
switch 3.
Using switches 28, 29 (Option) the control of Current and Arc length setting is transferred to a remote
regulator, i.e. push me pull you torch.
Interpulse Welding
Rotary switch (5) must be rotated into the inter-pulse position. Using the MFD (19) and rotary switch (6)
the following 5 Main Menu’s be activated;
Material
New job
Throat thickness
Interpulse
Pulse form
Using rotary switch (6), select from the main menu ‘Interpulse’, by now pressing the switch (6) the cursor
will return to the program last used in this mode. The programmable inter-pulse range runs from 0 –
100. The smaller the number the quicker the Pulsing, this gives the weld bead a very fine Scaling
11
appearance. A larger number would indicate an overall slow Pulse and consequently a larger scaling
appearance in the weld bead. To save the selected inter-pulse setting simply press switch (6) once.
MMA Welding
Rotary switch (6) must be rotated into the ‘Electrode’ position. Important, no load voltage is
immediately present at the cable connection plugs. Using the MDF (19) and the Rotary switch (6) the
following 4 sub-menu’s can be accessed;
Hotstart t (time)
Hotstart I (current)
Arc force (current trim)
New Job
The relevant settings can be selected through these sub-menus and altered to suite. The required
settings can also be programmed under a job number.
Hotstart
Hotstart is a process whereby the current to the electrode is increased for a programmed time during the
start phase of the MMA process.
Available settings:
Hotstart time
0 – 2s
Hotstart current
20 – 450/550 A
Arcforce (current trim)
•
•
A current increase is delivered through the electrode as a result of the electrode coming into
contact with the weld pool.
The increase in current ensures that the electrode does not stick to the work piece, however
should this phenomenon occur the current is automatically reduced in order to avoid the
overheating of the electrode.

Using button (18) the gas flow can be tested as follows:
Press button (18): the gas valve will be activated
Release button (18): the gas valve remains active
Press button (18): the gas valve will be de-activated.
As an added safety measure the gas valve will automatically close after 10 seconds should the button
not be manually operated during testing.
7.12 Selecting the Current control
Rotary switch (3) is used to select between which method of welding current control is preferred.
Potentiometer
With rotary switch (3) in the upper position the welding current and the arc length correction can be
controlled using potentiometers (1 & 2) on the main welding machines control panel. Using switch (28)
the control is transferred to which ever form of remote control is connected at that time.
14
Wire Feed Unit Potentiometer
With rotary switch (3) in the second position, control of the welding current and arc length correction is
controlled using potentiometers (25 & 26) on the front face of the wire feed unit.
TEDAC
With rotary switch (3) in the TEDAC position the control of the welding current and arc length correction
is controlled through the thumb switch mounted in the back of the welding torch itself. Warning: the
maximum current available is determined through the position of welding current potentiometer (25) on
the front face of the wire feed unit.
JOB-Functions
New JOBs
Rotary switch (3) must be set to control the current setting through the main control panel (1); the wire
feed unit (25), or the TEDAC torch system. Using the multi function display (MFD19) and rotary switch
(6) select the desired welding program, then with the help of the welding current potentiometer and the
arc length correction potentiometer set the desired welding conditions.
With rotary switches (5, 6) select the desired operational mode and welding process. The saving of the
new welding conditions is achieved using rotary switch (6). The switch (6) must be turned until the main
menu heading ‘New Job’ appears, the number of the next free program slot will then appear in the multi
functional display (MFD19) window, by pressing switch (6) once the program will be saved to the
machines memory and the number of that particular program will appear the MFD (19).
The possibility of saving the desired welding conditions to a job number other than the next available
free job is also possible; this is achieved through rotary switch (6). As above the rotary switch (6) must
be used to select the main menu ‘New Job’, when the next available free job appears in the multi
functional display rotary switch (6) can then be used to select the desired program number, by then
pressing rotary switch (6) twice the welding conditions will loaded into the chosen slot. The MFD (19)
will then return to the main menu heading ‘New Job’ to indicate that the transaction was successful.
Important: When a job is saved to a specific job number the complete job including all the fine tuning
elements of the program is saved (e.g. Inductance, pulse form, start current, down slope time, 2-stroke,
4-stroke, MIG/MAG, pulse-arc etc, etc).
Load saved JOB
If there are a number of jobs saved in the machines memory banks, then these programs can be
reselected and loaded back into the machine using rotary switch (3). The menu heading ‘job’ in the MFD
(19) is selected, the cursor will then show ‘Load Job’, again in the middle of the MFD (19) the job shown
in the display is now active and can be used. Notice: Job that appears in the MFD (19) will always be the
last saved program.
Should another previously saved program be required this can be loaded back into the welding machine
by pressing rotary switch (6) once, the cursor will jump across to the smaller job number field in the
bottom right of the MFD (19), by turning rotary switch (6) the desired program can be selected and is
now active. Only saved job programs can be reactivated.
If a TEDAC torch system is being used, then using the thumb control button mounted on the torch a
maximum of 10 programs can be selected and activated through this system. The programs should be
selected in ascending order through the MFD (19) i.e. the lowest number should be the first job.
15
Change JOB
The parameters in each saved job can be adjusted at any time. To achieve this rotary switch (3) must be
in the “JOB” positions, then using rotary switch (9) select the “Change” sub heading, now each individual
parameter is accessible and can be changed through the turning and pressing of rotary switch (9).
8
Maintenance and Accident Prevention
The maintenance of the welding machine consists of a regular cleaning and inspection. It
depends on the environment of the working area and the working hours.
The machine should be cleaned in regular intervals to guarantee a proper operation. The length
of the cleaning interval depends on the operation time, surrounding atmosphere etc.
ATTENTION:
Before opening the welding machine, make sure
that it is disconnected from the mains supply. Wait for
components to be sufficiently cooled down !
Wait until the capacitors are discharged (appr. 3 min.)!
9
Cleaning
IMPORTANT:
!!! Before opening the machine, disconnect it from mains !!!
Wait until the capacitors are discharged (appr. 3 min.)!
Welding unit:
Open the side covers. Remove dust from all parts of the machine.
Blow away the dust at the pcbs of the inverter withcompressed air,
reduced pressure (appr. 0,5 – 1 bar). We recommend to clean the unit
in regular periods.
Welding torch:
Control the welding torch after welding of 50 kg wire. Remove, clean
and replace the wire core. Clean with a cleaning solvent. Blow dry with
reduced compressed air. When replacing the wire core, insure that there are
no kinks. The gas nozzle must be sprayed with a silicon-free spray to
prevent the weld spatters from sticking to the nozzle. The contact tip is
a consumable item and must be replaced as required.
Attention: ⇒ Do not oil the wire core or the drive roller on the wire feed unit.

10 Aluminium Welding
1. Aluminium welding wire:
- Wire diameter 0.8 mm only with push pull torch
- Wire Al-Mg 3/5/4.5 Mn (1.0 mm), Al-Si, Al 99.5 (1.0 and 1.2 mm) torch lead max. 3 m
- For welding wire 1.6 mm we recommend a torch with a long torch head
- Do not store alu wire without the plastic protection cover. Do not use alu wires with oxid.
2. Teflon liner:
- For wire 0.8 - 1.2 mm we recomend the teflon liner (red, 2.0 x 4.0) mm (part-no.
022.1.0586)
- For (1.2) and 1.6 mm teflon liner (black, 2.7 x 4.7) (part-no. 022.1.0588)
- The carbon teflon liner must be installed without any break from the contact tip to the
drive roller
- Fix the clamping nut at the Euro connector only by hand
4. Wire feeding rollers:
- Exchage the two lower roller to aluminium rollers (U-groove), the rollers at the to may
remain pressure rollers without a groove
5. Pressure of the rollers:
- Reduce the pressure to a minimum.
- When the alu wire is stoped at the contact tip the rollers must turn without transporting
the wire.
6. Insertion of the wire:
- Insert the wire without a contact tip at the torch.
- Hold the torch cable straight, outherwise the wire could go through the line and the torch
lead.
7. Welding torch:
- We do not recommend the torch SB/SBT 307 G or SB/SBT 350 G for aluminium welding.
Use a ceramics gas distributor (not fibre glas). Due to the high temperatures the fibre glass
may emit a gas which influences the welding process.
- The torches SB/SBT 502 W and SB/SBT 600 W have an open cooling system. Assures that
the componets are tightly fitted. Only minimum parts of water will make the aluminium
welding impossible.
8. Protective gas:
- We recommend argon 4.6, mixtures argon-helium can be used for thick aluminium plates
to avoid or reduce a pre-heating.
17
- Gas flow for a gas nozzle 17 mm:
wire 1.0 mm: aprox.12-14 l/min.
wire 1.2 mm: aprox. 14-16 l/min.
wire 1.6 mm: aprox. 18-22 l/min.
Avoid smaller gas nozzles.
If the gas hose between gas valve and cylinder is long, an impulse of too much gas is ejected
during the ignition process which could cause porosity. Our wire feeder boxes have a special
reduction device installed.
- For gas hoses longer than 10 m we recommend the installation of a pressure regulator
inside the welding unit.
- We recommend a regulator with an integrated ball-flowmeter.
9. Position and distance of the torch:
- Aluminium is welded in forward position, the torch is tilt aprox. 10 - 20°.
- Distance torch to work piece aprox. 10-15 mm. If the distance is too large, the protective
gas shield is not assured.
- Avoid draught (air movement in the room).
10. Cleanliness:
- Aluminium work pieces must be without any dirtying. Clean with alcohol or special
aluminium cleaner
- Avoid the storage under high humidity.
- Remove oxid when aluminium pieces have been stroed a lon time.
11. Additional wire equipment:
- In our general catalogues in section 10 we offer complete packages for wire equipments.
12. Special 4-stroke:
- We recommend to operate in the special 4-stroke mode with a higher start current. The
start current, the down slop and the final current can be adjusted at the digital control
unit.

11 MIG-Brazing
Increasing demands to reduce damages due to corrosion are the reasons for working more and
more with surface treated steel plates. Zinc is actually the best choice due to an ecomomic
solution.
Large quantities of galvanized steel plates are found in car production, building constructions,
ventilation and climate technique and in the domestic sector.
Zinc begins to melt at approximately 420° Celsius and vaporization starts at approximately at
906° Celsius. These caracteristics do not lead to good results during the welding process
because the temperature of the welding arc using steel wire rises up to appr. 1450-1520° C,
melting temp. at 2700° C. This high temperature would instantly start the vaporization process
of the zinc. Furthermore, vaporization and oxides can provoque porosity, failures or fissures in
the weld and instability of the arc. Therefor, galvanized steel plates require less heat input.
The notion „ MIG-Brazing“ stands for a hard-solder process carried out by MIG/MAG- or PulseArc welding units. Different wires are used :
CuSi 3 wire for joining galvanized steel plates. Other wire compositions ( f. ex. CuAl 8 or AlBz 8)
if aluminized steel plates or stainless steel are used.
The advantages of using these wires are:
¾ no corrosion at the welding joint
¾ minimized spatters
¾ maintaining of the zinc surface
¾ low heat input
¾ easy finishing works of the welding joint
¾ cathodic protection of the material in the close surroundings of the welding joint
As shield gas pure argon or mixtures with argon (Ar 97,5 % - CO2 2,5 %) are used. As a result an
almost blank welding joint surface is achieved. When thicker zinc surfaces are used (more than
15 micro-m) the arc gets instable due to the higher output of zinc vapours.
In this case a short or a spray arc with low arc voltages can be an advantage.
We recommend to mount a steel liner to the torch lead.
The PULSE ARC welding unit model HighPULSE 280 / 350 K is a multiprocess welding unit
equipped with welding programs as a standard including welding programs for joining
galvanized and aluminized steel plates. The setting of the energy is realized or by means of one
botton (synergic operation mode) at the machine or by the remote control system TEDAC
mounted at the torch. The steel plates can be brazed together or in the pulse mode or in the
MIG/MAG mode. The low weight offers an easy handling of the unit to different working places.
