TIG LIFT WELDING
DC TIG welding requires the use of gas (Argon). Connecting a valve torch will allow to manually adjust the supply of gas and connec-
ting a EURO torch will also offer capability to adjust downslope and post gas settings.
For TIG welding please follow the stages below :
TIG Lift Pro welding with a Euro torch
• See connection page 4.
• Connect the gas hose to the back of the machine and to the
gas bottle regulator.
• Adjust the gas flow on the gas bottle regulator.
• To strike an arc touch the piece of metal to weld and press the
torch trigger.
• Downslope and Post-gas start automatically once the trigger is
released. They can be adjusted on the device.
Adjustable Downslope (Euro torch only)
Time needed to shift from welding current to minimum current. Avoids cracks and craters at the end of welding. By default this fea-
ture is set up at 0 sec.
Adjustable Post-Gas (Euro torch only)
This parameter determines the time in which gas is released after the arc has stopped. It protects the weld pool and the electrode
against oxidisation whilst the metal is cooling after welding.
Recommended settings / Electrode grinding
0,5-5
4-7
To optimise the welding process, it is recommended to grind the electrode prior to welding as described in the diagram below
DUTY CYCLE AND WELDING ENVIRONMENT
• The welding unit described has a "constant current" output type. Its duty cycle following the norm EN60974-1 is indicated in the
table below :

MULTIPEARL 200.2 / 200.4 XL / 201.4 are Class A devices. It is designed to be used in an industrial or professional environment. In a
different environment, it can be difficult to ensure electromagnetic compatibility, due to conducted disturbances as well as radiation.
The device complies with the IEC 61000-3-12 standard.

TIG Lift EASY welding with a Valve torch
• See connection page 4.
• Connect the gas hose from the torch to the gas bottle
regulator.
• Adjust the gas flow on the gas bottle regulator and then open
the torch valve.
• Striking :
Touch the piece of metal to
weld with the electrode
• At the end of the weld :
Only stop the gas once the Tungsten electrode has cooled
down.
