Laser Welding vs. TIG Welding: What is the Difference machining powder metal partsrarely necessary usually a Argon arc welding
There are three styles of arc starting used in TIG welding: scratch start, lift start, and HF start. Scratch Start Scratch start is an older starting technique that is usually used with a transformer type of welding machine. Lift Start This start is more common with inverter welding machines.
