Welding Positioner

[Chewy]

Excellent! Have put it on to-do list. I have wanted something like that for years.

That is a professional job sir.

I think some one else asked it... @jbolt how do you mitigate the juice traveling to ground from the welder? I have all the parts to build one, but I'm afraid the amps from the TIG will blow something.

The welder ground is connected directly to the ground lug on the positioner housing. The ground strap inside makes a direct connection from the turntable shaft to the housing. This also keeps full current from traveling through the roller bearings and damaging them. The chassis of the speed controller and power supply are grounded to the housing through the mounting screws. The electronics are unaffected by the welder.

You need a rocker foot pedal for fwd/rev.

The speed controller has a fwd/rev switch. The foot pedal is on/off only.
