TIG WELDING with torch with valve

Functions
The TIG DC welding requires a gas protection (Argon).
To weld with TIG, follow the following steps:

  1. Connect the earth clamp to the positive (+) terminal.
    Plug a torch with valve on the negative (-) terminal.

  2. Plug the torch gas pipe onto the gas bottle regulator.
    It might be sometimes necessary to cut it before the nut if the nut is not adapted to the regulator/flowmeter.

  3. Adjust the intensity in relation to the thickness of metal to be welded (30A/mm)

  4. Adjust the gas flow on the regulator fitted to the gas cylinder (see following table), then open the valve of the torch

  5. To start
    • For the machines with the « LIFT » mode :

a-touch down the electrode with the base metal to be welded.

b- Lift the electrode 2-5mm away from the metal to be welded to start the arc
• For the other machines, scratch the electrode on the part to weld to start the arc.

  1. At the end of welding: quickly lift the torch, stop the gas only, whilst the electrode cooling.

Electrode grinding
For optimum functioning the tungsten electrode must be sharpened in the following way

    L = 2,5 x d
