Grounding the work table

[geezer]

In reply to Geezer, this is the way a welder fault could be hazardous: in normal tig setup, the machine has a short from negative (torch) to chassis. The work clamp, and the table are now at 60-80 volts above ground before the arc ignites. Could result in anything from a mild shock to electrocution, depending on how much you are sweating, what you are standing on, your shoes, etc. Maybe this is unlikely, but fault circuits are there to protect you in unusual circumstances.

Could happen, which brings up the simple safety rule, always place your earth clamp as close to your work as possible and never position your body between the earth clamp and the torch.

As far as special grounding goes I have seen old timers ground out pieces on large equipment they are welding on to prevent ball bearings on the machines they are welding repairs on from arcing. Does it help, dunno but it can't hurt.
