You can without tools move or twist grips on the lower surface of the handle into such
position you like that you can get a steady hold on the torch. You can also easily remove one
or both of the grips through the front end of the handle.
2.4 ChOiCe OF eleCTrOde size and FlOW amOunT OF shielding gas
Electrode size and shielding gas flow are defined by welding current level. The most usual
shielding gas for TIG welding is argon.
The table below is given only as a guide.
