TIG 185AC/DC FP Operating manual 2. Gas Tungsten Arc Welding (GTAW/TIG). Shielding gas is directed into the arc area by the welding torch and 2.1 Introduction a gas lens within the torch distributes the shielding gas evenly over the weld area. In the torch the welding current is transferred to The Tungsten Inert Gas, or TIG process, uses the heat generated the tungsten electrode from the copper conductor.

Straight polarity is used mainly for welding: •...
Page 10: Shielding Gas Selection
TIG 185AC/DC FP Operating manual 2.4 Shielding gas selection Brass With argon, the arc is stable and there is little smoke. Cobalt-based alloys Argon provides a stable, easy-to-control arc. Copper nickel Argon gives a stable, easy-to-control arc. Also used for welding copper nickel to steel. (Monel) Deoxidised copper Helium is preferred as it helps greatly in counteracting thermal conductivity of copper.

Correct travel speed for normal welding applications varies between For further help on choosing the right electrode for your work approximately 125–375 mm per minute, depending on electrode please contact your local Messer supplier. size, size of run required and the amperage used. Welding current Excessive travel speeds lead to poor fusion, lack of penetration, etc.
Page 14: Types Of Joints
TIG 185AC/DC FP Operating manual Correct work preparation The method of preparation of components to be welded will depend on equipment available and relative costs. Methods may include sawing, punching, shearing, lathe cut-offs, flame cutting and others. In all cases edges should be prepared for the joints that suit the application.
