Shielding gas is used in DC TIG welding. Your dealer will give you advice on
choosing gas and equipment. Open the gas valve on the TTM 15V TIG torch.
When gas starts to flow, arc is lit by lightly scratching work piece with the tip
of the tungsten electrode. When arc is lit, its length is regulated by holding
the tip of the tungsten electrode at a suitable distance from the work piece.
Move the torch forwards from the starting point, usually in appr. 10-15°
pushing angle forwards. If necessary, regulate current rate. Stop welding by
lifting the torch off the welding piece and by closing the gas valve on the
torch.
NOTE!
Always fix the gas cylinder so that it stays steadily in upright
position either in specially made wall rack or cylinder trolley. Always
close the cylinder valve after having finished welding.
