Grounding
It's all in the grounding, and making sure the current goes through the ground clamp to ground, and not you. So don't think only about the connection between the piece being welded on and the welder, but also from the welder to ground. The current needs to make the complete trip. Saw a guy cut the ground electrode off his 110v welder, then wonder why he got shocked all the time.
Ok, here comes the OG story. Years ago, when I was District Manager for Hobart Arc Welding, we would lease engine driven welders to the Cheveron Refinery in the SF Bay Area. We got called out because a welder was malfunctioning. Seems every time a welder started to weld on pipes, a guy about 100' away would get shocked when he stepped in a particular puddle. It was a simple grounding problem.
