Default Zapped while tig welding

I bought my first Wire feed welder about 15 years ago, and took a tig class about 3 years ago. Tig welder is about a year old now. I logged hundreds of hours but today on it already but today I experienced something new. Even with gloves and a well placed and clean ground clamp, I was getting zapped while installing a new quarter skin on my friends car.

I made it about an inch and my hand was tingling while feeding the wire. I stopped for a bit and tried again with clamp in a new position but same result.

Has this happened to you?

I have been lit up pretty good when welding aluminum on a hot day. Sweaty gloves can make the leather much more conductive.

What kind of welder do you have?

Default Which hand?

Makes a difference...


Hand with the torch, or hand with the filler rod?

Default 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.
