• Thin sheet and stainless steel may be welded with or without filler, similar

to gas welding.

• The filler is fed in at the edge of the pool. The rod must not touch the tip of

the electrode or enter the arc. The end of the rod must always be shielded

by the argon atmosphere to prevent as far as possible the formation of

oxides of its surface. When welding stainless steel and copper, it is often

possible to feed in the filler continuously at the edge of the pool.

• The arc length generally varies between 3 and 6 mm depending on the

type of joint, type and thickness of material and so on.

• The torch is advanced in the direction of welding, without lateral

movement, maintaining the torch angle of 45o to the workpiece.

(A TIG torch kit is not supplied with the machine. These are available from your

CLARKE dealer (Part number 6012232/6012239).
