I still do that with a plasma cutter a lot. You know, fire her up, she won't cut, take the torch apart to check it, check all the settings, step back from the cutter and hear a crunch, and look down to find out your standing on the ground clamp...
I've repeatedly asked ESAB on facebook for a welder and plasma cutter that doesn't need a ground clamp... Or a cordless wirefeed welder...
I've cut many a ton of steel with an ESAB! Mine worked the same way.....wouldn't cut worth a fizzle with the ground clamp laying on the floor! Now the idea of these units not needing a clamp would be awesome!
Here's a good one....send the new apprentice down to the welding supply to pick up a bottle of plasma gas for the cutter!
