SAFETY
Arc welding can be dangerous and can cause serious and even fatal
injuries
Protect yourself and others
Ensure the following safety precautions are taken:
Arc radiation
Protect yourself with a hamlet fitted with filters
Rain, steam, damp Use your welding unit in a clean/dry environment, on a flat surface.
Electric shock
Falls
This device must only be used with an earthed power supply. Do no
touch high voltage parts. Check that the power supply is suitable for
this unit
Ensure the unit is placed in a stable position to prevent the machine
from falling onto prople/objects
Burns
Wear protective (fire-proof) clothing (cotton, overalls or jeans).
Wear protective gloves and a fire-proof apron
Ensure other people keep a safe distance from the work area and do
not look directly at welding arc.
protect others by installing fire-proof protection walls.
Fire risks
Remove all flammable products from the work area. Do not work in
presence of flammable gases
Fumes
Do not inhale welding gases and fumes. Use the device in a well
ventilated environment, with artificial extraction if welding indoors
Additional
Precautions
Any welding operation undertaken in.....
- rooms where there is an increased risk of electric shocks,
- poorly ventilated rooms,
- in the presence of flammable or explosive material,
should always be approved by a "responsible expert”, and made in
presence of people trained to intervene in case of emergency.
Technical protection as described in the Technical Specification
CEI/IEC 62081 must be implemented. Welding in raised positions is
forbidden, except in case of safety platforms use.

TIG/DC operation
Data setting: Choose the TIG /DC model, DC welding function, LIFT/HF ,
2T/4T, adjust the pre gas time, arc current, slope up time, peak current, slop
down time, crater current, slope down time.
1. Pre gas time setting: In order to ensure that the workpiece and the
tungsten from contamination and burnout, set the pre gas time to let go
argon air to push out the rest air in the torch. The pre-gas provides
protection for the area where the welding pool will be formed. It also
improved stability when the welding arc is created.
2. Arc current Setting: Usually set the current less than the max current.
3. Slop up time Setting: Time needed to go from minimum current welding
current.
4. Max Current: It is the welding current. Set the current refer to the TIG
welding table.
5. Slop down time Setting: Time needed to shift from welding current to
minimum current. Avoid cracks and craters at the end of welding.
6. Crater current Setting: Usually set the current less than the max current.
7. Post gas time Setting: In order to ensure that the workpiece and the
tungsten from contamination and burnout, set the pre gas time to let go
argon air keep some time. It protects the weld poil and the electrode
against oxidization whilst the metal is cooling after welding.

TIG welding techniques
The suggested electrode and welding rod angles for welding a bead on plate.
The same angles are used when marking a butt weld. The torch is held 60-75o
from the metal surface. This is the same as holding the torch 15-30o from the
vertical. Take special note that the rod is in the shielding gas during the
welding process
TIG/DC/PULSE Operation
Data setting: Choose the TIG /DC model, Pulse welding function, LIFT/HF ,
2T/4T, adjust the pre gas time, arc current, slope up time, peak current, base
current, slop down time, crater current, slope down time, pulse frequency,
pulse ratio..
1. Base current setting: Usually set in a small value as long as not break the
arc.
2. Pulse ratio setting: The ratio determines the hear input, the bigger ratio it
is, the weld seam is wider and deeper and vice versa. Usually set the ration
between 30%-70%.
3. Pulse frequency setting: The higher frequency it is, the weld seam
denser and vice versa.

TIG/AC Operation
Data setting: Choose the TIG /AC model, , LIFT/HF , 2T/4T, adjust the pre
gas time, arc current, slope up time, peak current, slop down time, crater
current, slope down time, AC frequency, AC balance.
1. AC frequency setting: The higher frequency it is , the arc concreted more
intensive, weld seam smoother, but the sound of arc relatively shrill.
Usually suggest the low AC frequency.
2. AC Balance (EP ratio) setting: It is the percentage of AC negative wave
against AC period. The higher it is, the weld seam smoother, but the
penetration more shallow, tungsten worn easier. Usually suggest the low
EP ratio
TIG/AC/Pulse Operation
Data setting: Choose the TIG /AC model, Pulse welding function, LIFT/HF ,
2T/4T, adjust the pre gas time, arc current, slope up time, peak current, base
current, slop down time, crater current, slope down time, Pulse frequency ,
