Frequently Asked Questions
Which gas is used for TIG welding?
100% argon is used most often. The calculator estimates the gas flow according to current, material and working conditions.
What is the difference between HF and TIG Lift?
HF starts the arc without contact with the workpiece. TIG Lift starts the arc by lightly touching the workpiece and lifting the torch. HF is generally more convenient for precision work.
When should AC mode be used?
AC mode is mainly used for aluminium and magnesium alloys because it helps break down the oxide layer while providing fusion of the base material.
When should manual pulse be used?
Manual pulse helps control heat input, reduce distortion and improve weld pool control, especially on thin materials and in difficult positions.
