Scratch the tip of the electrode on soon as an arc develops, quickly withdraw the electrode to
maintain a gap of approx 3-4 mm, and proceed to weld. (See notes below).
To stop welding, simply remove the torch from the workpiece. This method is referred to as
‘Scratch Arc’.
REMEMBER to turn OFF the gas immediately you finish welding.
NOTES:
a) To avoid a visible strike mark on the surface of the workpiece, it is advisable to
strike the arc in the joint, where the mark will be concealed by the weld.
b) 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.
c) The arc length generally varies between 3 and 6mm depending on the type of joint,
type and thickness of material, and so on.
d) The torch is advanced in the direction of welding, without lateral movement,
maintaining the torch angle of 45

Guidelines for the TIG welding current needed and recommended electrode sizes
etc. for different gauges of material are shown on the following chart:
