1. GENERAL DESCRIPTION
Connects to any primary voltage between 195 and 265V without need for any action from the
operator.
Line Voltage compensation keeps output of the power source constant regardless of fluctuation in
input power from 10% below lowest to above highest rated input voltage.
Safe in use. Touchable Open Circuit Voltage only 9V, well below the 70V limit set by the Code of
Safe Working Practices for Merchant Seamen.
Automatic Hot Start for stick arc starts makes arc striking easy and prevents electrode sticking.
Automatic Arc Force for stick electrode welding allows the arc characteristics to be changed for
specific applications and electrodes.
Lift-Start in TIG mode provides easy and soft TIG arc starting.
Step-less adjustment of welding current through whole current range: 10 –180A in MMA mode, 5 – 200A in TIG
mode.
Casing of high grade aluminium and industrial plastic to eliminate corrosion damage also contributes
to low-weight which together with compact outer dimensions provides good portability.
Wind tunnel design for the internal cooling air flow protects electrical components and PC boards
from dirt, dust, debris, greatly improving reliability.
Thermal overload protection with indicator lights helps prevent machine damage if the duty cycle is
exceeded or airflow is blocked.
Total Protection function with indicator light prevents machine damage if the primary power supply exceeds
275V.

3. INSTALLATION
Only qualified personnel should perform this installation.
Only personnel that have read and understood this Manual should install and operate this
equipment.
Machine must only be plugged into a receptacle which is grounded in accordance with valid
regulations.
Note
The power switch should be in the OFF position when installing work cable and electrode cable and
when connecting power cord to input power.
Select a suitable location
The UW I 230 TP AC/DC inverter welder has an IP23S rating. Locate the welder in a dry location
where there is free circulation of clean air into the louvers in the back and out the front of the unit.
Ensure minimum 50cm free space on all sides. If free flow of air is hindered the machine will
overheat.
A location that minimizes the amount of smoke and dirt drawn into the louvers reduces the chance of
dirt accumulation that can block air passages and cause overheating.
Avoid tilting
The machine must be placed on a secure, level surface, maximum 15º out of horizontal.

5. WELDING
MMA (SMAW stick electrode) welding
Select MMA welding.
Connect ground (return) cable with good contact to
the work piece.
Select polarity and amperage as recommended for
the electrode and start arc as follows:
Drag electrode across work piece like striking a
Match and lift electrode slightly after touching work.
If arc goes out electrode was lifted to high.
If electrode sticks to work piece, use a quick twist to
free it.
1 Electrode
2 Workpiece
3 Arc
Hot start
The machine has automatic Hot Start for stick electrode welding. This makes arc striking easier and
reduces the possibility of electrode sticking
Arc Force
Automatic Arc Force 50% for stick electrode welding provides optimal arc characteristics for various electrodes.
TIG (GTAW) welding
Select TIG process and connect TIG torch to negative (-) terminal on the machine. The torch
should preferably have gas valve on the handle. Connect ground (return) cable with good contact
to the work piece.
W hen the TIG process is selected normal open-circuit voltage is not present before tungsten
electrode touches and lifts from work piece. Only a low sensing voltage is present between
electrode and work piece.
The solid-state output contactor does not energize until after electrode is touching work piece.
This allows the electrode to touch the work piece without overheating, sticking, getting contaminated
or contaminate the work piece.
Start the arc as follows:
Turn gas on.
Touch tungsten electrode to workpiece at weld start point.
Hold electrode to workpiece for 1-2 seconds, and slowly lift electrode.
The arc is formed when the electrode is lifted.

Lift carefully and the arc will
be establishe
6. PARALLEL CONNECTION
Two pcs UW I-230 TP AC/DC may be parallel connected and will then supply up to 360A current
for stick electrode welding. This is done as follows:
-
Set both machines to MMA welding.
-
Set both machines to remote control and if extensions are necessary use same length
remote control cables from each machine to the work site where the remote control parallel
connection kit, product number 676973, is used to connect both machines to the same
remote control
-
If remote control is not used both machines should be set to the same ampere value on the
displays, half of the required value for the electrode
-
Return cables from both machines should be of equal length and clamps should be
connected close together directly on a clean part of the work-piece. 70mm2 cable is
recommended. NB! Same polarity for both on the welding machines.
-
Welding cables from both machines must be of equal length to the work site where the
parallel connecting three-way connector DIX70 male-female-female, product number
632901 is used to connect both machines to the same electrode holder.

12. SAFETY INSTRUCTIONS
Arc Welding Hazards
The safety information given below is only a summary of the more complete safety information found
in the Safety Standards listed in Section 1-5. Read and follow all Safety Standards.
Only qualified persons should install, operate, maintain, and repair this unit. During operation, keep
everybody, especially children, away.
ELECTRIC SHOCK can kill.
Touching live electrical parts can cause fatal shocks or severe burns. The electrode and work circuit
is electrically live whenever the output is on. The input power circuit and machine internal circuits are
also live when power is on. In semiautomatic or automatic wire welding, the wire, wire reel, drive roll
housing, and all metal parts touching the welding wire are electrically live. Incorrectly installed or
improperly grounded equipment is a hazard.
Do not touch live electrical parts. Wear dry, hole-free insulating gloves and body protection. Insulate
yourself from work and ground using dry insulating mats or covers big enough to prevent any
physical contact with the work or ground. Do not use AC output in damp areas, if movement is
confined, or if there is a danger of falling. Use AC output ONLY if required for the welding process. If
AC output is required, use remote output control if present on unit.
Disconnect input power before installing or servicing this equipment. Always verify the supply
ground − check and be sure that input power cord ground wire is properly connected to ground
terminal in the cord plug and that the plug is connected to a properly grounded receptacle outlet.
W hen making input connections, attach proper grounding conductor first − double-check
connections. Frequently inspect input power cord for damage or bare wiring −replace cord
immediately if damaged − bare wiring can kill. Turn off all equipment when not in use.
Do not use worn, damaged, undersized, or poorly spliced cables. Do not drape cables over your
body. If earth grounding of the work-piece is required, ground it directly with a separate cable. Do not
touch electrode if you are in contact with the work, ground, or another electrode from a different
machine.
Use only well-maintained equipment. Repair or replace damaged parts at once. Maintain unit
according to manual. Wear a safety harness if working above floor level. Keep all panels and covers
securely in place. Clamp work cable with good metal-to-metal contact to work-piece or worktable as
near the weld as practical. Insulate work clamp when not connected to work-piece to prevent contact
with any metal object. Do not connect more than one electrode or work cable to any single weld
output terminal.
SIGNIFICANT DC VOLTAGE exists after removal of input power on inverters. Turn off inverter,
disconnect input power, and discharge input capacitors before touching any parts
Revision date: 01/07/2015
Page 19 of 24
FUMES AND GASES can be hazardous.
Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your
health. Keep your head out of the fumes. Do not breathe the fumes. If inside, ventilate the area
and/or use exhaust at the arc to remove welding fumes and gases. If ventilation is poor, use an
approved air-supplied respirator. Read the Material Safety Data Sheets (MSDSs) and the
manufacturer’s instructions for metals, consumables, coatings, cleaners, and degreasers.
Work in a confined space only if it is well ventilated, or while wearing an air-supplied respirator.
Always have a trained watchperson nearby. Welding fumes and gases can displace air and lower the
oxygen level causing injury or death. Be sure the breathing air is safe.
Do not weld in locations near degreasing, cleaning, or spraying operations.The heat and rays of the
arc can react with vapors to form highly toxic and irritating gases.
Do not weld on coated metals, such as galvanized, lead, or cadmium plated steel, unless the coating
is removed from the weld area, the area is well ventilated, and if necessary, while wearing an airsupplied respirator. The coatings and any metals containing these elements can give off toxic fumes
if welded.
ARC RAYS can burn eyes and skin.
Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays
that can burn eyes and skin. Sparks fly off from the weld. Wear a welding helmet fitted with a proper
shade of filter to protect your face and eyes when welding or watching. W ear approved safety
glasses with side shields under your helmet. Use protective screens or barriers to protect others from
flash and glare; warn others not to watch the arc. W ear protective clothing made from durable, flameresistant material (leather and wool) and foot protection.
WELDING can cause fire or explosion.
Welding on closed containers, such as tanks, drums, or pipes, can cause them to blow up. Sparks
can fly off from the welding arc. The flying sparks, hot workpiece, and hot equipment can cause fires
and burns. Accidental contact of electrode to metal objects can cause sparks, explosion,
overheating, or fire. Check and be sure the area is safe before doing any welding. Protect yourself
and others from flying sparks and hot metal. Do not weld where flying sparks can strike flammable
material. Remove all flammables within 35 ft (10.7 m) of the welding arc. If this is not possible, tightly
cover them with approved covers. Be alert that welding sparks and hot materials from welding can
easily go through small cracks and openings to adjacent areas. Watch for fire, and keep a fire
extinguisher nearby. Be aware that welding on a ceiling, floor, bulkhead, or partition can cause fire
on the hidden side. Do not weld on closed containers such as tanks, drums, or pipes, unless they are
properly prepared Connect work cable to the work as close to the welding area as practical to
prevent welding current from travelling long, possibly unknown paths and causing electric shock and
fire hazards. Do not use welder to thaw frozen pipes. Remove stick electrode from holder or cut off
welding wire at contact tip when not in use. Wear oil-free protective garments such as leather gloves,
heavy shirt, cuff-less trousers, high shoes, and a cap. Remove any combustibles, such as a butane
lighter or matches, from your person before doing any welding.
FLYING METAL can injure eyes.
Welding, chipping, wire brushing, and grinding cause sparks and flying metal. As welds cool, they
can throw off slag. W ear approved safety glasses with side shields even under your welding helmet.
BUILDUP OF GAS can injure or kill.
Shut off shielding gas supply when not in use. Always ventilate confined spaces or use approved airsupplied respirator.
Revision date: 01/07/2015
Page 20 of 24
HOT PARTS can cause severe burns.
Do not touch hot parts bare handed. Allow cooling period before working on gun or torch.
MAGNETIC FIELDS can affect pacemakers.
Pacemaker wearers keep away. Wearers should consult their doctor before going near arc welding,
gouging, or spot welding operations.
NOISE can damage hearing.
Noise from some processes or equipment can damage hearing. W ear approved ear protection if
noise level is high.
CYLINDERS can explode if damaged.
Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can explode. Since
gas cylinders are normally part of the welding process, be sure to treat them carefully. Protect
compressed gas cylinders from excessive heat, mechanical shocks, slag, open flames, sparks, and
arcs. Install cylinders in an upright position by securing to a stationary support or cylinder rack to
prevent falling or tipping. Keep cylinders away from any welding or other electrical circuits. Never
drape a welding torch over a gas cylinder. Never allow a welding electrode to touch any cylinder.
Never weld on a pressurized cylinder − explosion will result. Use only correct shielding gas cylinders,
regulators, hoses, and fittings designed for the specific application; maintain them and associated
parts in good condition. Turn face away from valve outlet when opening cylinder valve. Keep
protective cap in place over valve except when cylinder is in use or connected for use. Read and
follow instructions on compressed gas cylinders, associated equipment, and CGA publication P-1
listed in Safety Standards.
Additional precautions for installation, operation, and maintenance
Do not install or place unit on, over, or near combustible surfaces. Do not install unit near
flammables. Do not overload building wiring − be sure power supply system is properly sized, rated,
and protected to handle this unit.
FALLING UNIT can cause injury.
Use lifting eye to lift unit only, NOT running gear, gas cylinders, or any other accessories. Use
equipment of adequate capacity to lift and support unit. If using lift forks to move unit, be sure forks
are long enough to extend beyond opposite side of unit.
OVERUSE can cause OVERHEATING
Allow cooling period; follow rated duty cycle. Reduce current or reduce duty cycle before starting to
weld again. Do not block or filter airflow to unit.
STATIC (ESD) can damage PC boards.
Put on grounded wrist strap BEFORE handling boards or parts. Use proper static-proof bags and
boxes to store, move, or ship PC boards.
MOVING PARTS can cause injury.
Keep away from moving parts. Keep away from pinch points such as drive rolls.
WELDING WIRE can cause injury.
Do not press gun trigger until instructed to do so. Do not point gun toward any part of the body, other
people, or any metal when threading welding wire.

MOVING PARTS can cause injury.
Keep away from moving parts such as fans. Keep all doors, panels, covers, and guards closed and
securely in place.
H.F. RADIATION can cause interference.
High-frequency (H.F.) can interfere with radio navigation, safety services, computers, and
communications equipment. Have only qualified persons familiar with electronic equipment perform
this installation.
The user is responsible for having a qualified electrician promptly correct any interference problem
resulting from the installation.
If notified about interference, stop using the equipment at once. Have the installation regularly
checked and maintained. Keep high-frequency source doors and panels tightly shut, keep spark
gaps at correct setting, and use grounding and shielding to minimize the possibility of interference.
ARC WELDING can cause interference.
Electromagnetic energy can interfere with sensitive electronic equipment such as computers and
computer-driven equipment such as robots.
Be sure all equipment in the welding area is electromagnetically compatible.
To reduce possible interference, keep weld cables as short as possible, close together, and down
low, such as on the floor.
Locate welding operation 100 meters from any sensitive electronic equipment.
Be sure this welding machine is installed and grounded according to this manual.
If interference still occurs, the user must take extra measures such as moving the welding machine,
using shielded cables, using line filters, or shielding the work area.
EMF Information
Considerations about welding and the effects of low frequency electric and magnetic fields.
Welding current, as it flows through welding cables, will cause electromagnetic fields.
There has been and still is some concern about such fields.
However, after examining more than 500 studies spanning 17 years of research, a special blue
ribbon committee of the National Research Council concluded that: “The body of evidence, in the
committee’s judgment, has not demonstrated that exposure to power-frequency electric and
magnetic fields is a human-health hazard.”
However, studies are still going forth and evidence continues to be examined. Until the final
conclusions of the research are reached, you may wish to minimize your exposure to
electromagnetic fields when welding or cutting.
To reduce magnetic fields in the workplace, use the following procedures:
1. Keep cables close together by twisting or taping them.
2. Arrange cables to one side and away from the operator.
3. Do not coil or drape cables around your body.
4. Keep welding power source and cables as far away from operator as practical.
5. Connect work clamp to workpiece as close to the weld as possible.
About Pacemakers:
Pacemaker wearers consult your doctor first. If cleared by your doctor, then following the above
procedures is recommended.
