TIG LIFT WELDING
The DC TIG welding requires a protective gas (argon).
Follow the steps as below:
1. Connect the earth clamp on the positive pole (+).
2. Connect a torch "valve" on the negative polarity (-).
3. Connect the pipe gas torch on the gas cylinder
4. Select TIG mode using the selector button .
5. Adjust the wished current (display ) using the keys .
Advice: Take 30A/mm as a default setting and adjust according to the part to weld.
6. Set the gas flow on flewmeter of the gas cylinder, and then open the valve of the torch
7. To boot :
a- Touch the electrode on the
welding part
8.
At end of welding :
a. For IMS 170: raise the torch for a quick gesture, do not cut the gas only after electrode cooling.

To optimize the working, you have to use an electrode grinded as below :

THERMAL PROTECTION & DUTY CYCLE
• Thermal protection: thermal protection indicator turns on and the cooling time is about 2 to 5 min according to external
temperature.
• Leave the machine connected to the supply after welding in order to let it cool down
• The welding unit describes an output characteristic of "constant current" type. The duty cycles following the norm
EN60974-1 (at 40°C on a 10mn cycle) are indicated in the table here below :
To adjust the Hot Start and Arc Force, go through the following steps:
Press the selector during 3 seconds.
The inscription "HS" (Hot Start) starts blinking and a number appears.
Set the required percentage ( display ) using keys
Valid the required figure by pressing the selector button
The inscription "AF" (Arc Force) starts blinking then one figure appears
Set the required percentage (display ) using keys .
Valid the required figure by pressing the selector button.
