Looking for a better connector for welders in the shop , currently they are nema 6-50s. The extension cords for them are a recept in a 4square with raised covers , the boxes constantly fall apart from rough handling , looking for go twist lock , but don't want to use the temp cord style ones , the welders only use 3 wire cords , but other equipment uses the temp cord style cord caps. Someone using the wrong cord would cause a issue of course , any ideas for a twist lock ?

Haha no. Sorry I didn't read your post close enough.

All of our welders over 30 amps are stationary and direct wired off a sidearm disconnect.

Funny thing is the units come with 6-50s on 10 or 12 gauge cords

One possibility is Arrow-Hart (I think....) makes 6-50 cord connectors and straight plugs.

Yes, they're plastic, but they seem to hold up better than 4 sq.s with recepts.

The 50 amp temp cord twistlocks can be used for 240 volt single phase welders; just use the two hots for the welder plugs.

Is changing out the cord on the welder an option or is it really drawing that much current?

The temp. Cord caps can't be used for our welders , they are already in use for the roving plasma cutters , they require a neutral , wouldn't work well for some dipahit to connect the plasma to the welder cord. Without a noodle been down that road once

Also trying to get away from the right angle ness of the 6-50 s. Had a rocket scientist let a finger slip over the edge of the plug and touched a blade , he said it hurt :laughing:

The A/H 6-50s are straight blade. They look like a giant standard household 15 amp 125 volt connector and plug.

Also, the 50 amp twistlock cords would have neutrals, but the plug attached to the welder cord would have only the two hots and the ground. This way, the neutral is always present, but it's not used when a welder is plugged in.

I'll have to check out the arrow hart ones. , the current welder extension cords are only 3 wire

The 50A locking devices are made in other then the 125/250V California standard, but I suspect they do not come cheap.
