Can flat steel be used as a substitute for the ground wire in a welding machine’s secondary circuit? What are the risks?
Irregular, high resistance, prone to overheating; there is a risk of sparks
No, it’s easy to encounter electric shock hazards
I think since it’s a DC welder itself, using flat steel for the secondary ground wire shouldn’t pose any danger

The circuit current of the welding machine is very high. Using objects such as rebar as ground wires poses serious safety risks, as iron-based materials like rebar have high electrical resistance. Every year in our country, there are many accidents involving welders caused by the use of steel rebar and pipes as welding circuits. For the welding torch cable, a dedicated flexible cable of the same diameter must be used as the ground wire
High resistance – what safety hazards?
