Hello all,

Iam thinking about putting some casters on the bottom of my Lincoln Tombstone stick welder, to move it around the shop easier.

The bottom of the welder has two steel feet welded to the frame - upon which the welder sits when in use.

I wonder if these feet also act as a ground for the machine? If so, if I raise the welder off the ground 3" or so, with rubber casters, would I also need to somehow attach a grounding cable to the machine?

Thanks
Glenn

Glenn: Ground is always carried through the power cable, in the case of 220 volt welders it's the neutral line which is grounded at the pole. However, adding an additional safety ground wire is a good idea. Most people don't do it cuz it requires a 4 wire plug, socket and cable. But to answer your question, the feet have nothing to do with the grounding. Raise it as high as you like.

Hi Glenn,
i got 6" rubber casters on mine, 2 swivel casters- 2 fixed.
it was the best thing i did next to welding a couple posts to the frame extending up past the top, to coil the leads around

Mark and Mike. thanks! I'll attack it on Monday! Real tired of dragging it around. Casters and an angle iron frame will do the trick, I think.

A friend set his on a dolly similar to this one at HF with 3" casters for $11 - cheaper than you can buy the casters.
