Dc Tig Welding - IPOTOOLS WIG INV185PACDC IGBT Digital Original Instruction Manual

3. Connect the hose of the gas bottle to connection 21.
4. Gas test: Switch on the device with switch 18, open the bottle screw of the
argon bottle and set the appropriate gas flow on the pressure reducer. When the
button on the burner is pressed, the solenoid valve in the device must open and
the gas must run out of the burner nozzle,
5. Select the welding process, see below,
6. When the welding process is complete, close the argon bottle and switch off the
welding machine.

1.3 DC TIG WELDING

1. Switch 13 to position »HF TIG« or »LIFT TIG«,
2. Set switch 6 to "Pulse off" and switch 12 to "DC",
3. Set the corresponding welding parameters on the welding curve with switch 8 and
use rotary control 9 to enter the value of the parameter on the welding curve,
4. The tip of the tungsten electrode should normally be extended 5 mm and be as
close as possible to the workpiece. To start welding, press the button on the torch.
Note: If switch 7 is set to "2T" during welding, the button on the torch must remain pressed
during the entire welding process. In "4T" mode, the switch only needs to be pressed briefly
at the beginning and at the end of the welding process.
5. At the end of the welding process, release the button on the torch, the welding
current will gradually decrease (the time can be set) and the arc will go out. At the
end of the welding time, hold the torch over the weld seam, the shielding gas
prevents air from penetrating into the weld seam and the weld seam does not oxidize.
