What do you mean by "ground arc" of argon arc welding machine? Is it because it doesn't arc or is it connected directly to the ground to prevent electric shock?

Answer:

Hello, ground wire and ground wire, grounding wire to prevent leakage from the welder shell to the earth line, safety protection. The wire or workpiece line is used to form an arc circuit with the welding torch
Some of the ground wires come from the positive electrode, some from the negative electrode, and the electrodes are marked or referenced. The electrodes are directly connected to the welded metal objects before welding.
In order to form a loop, not a safety problem, the welding gun is an electrode and the ground wire is an electrode, so as to form a welding arc
