outlets, plugs and connectors for Syncrowave 250 welder


Hi, I was wondering about wiring up my new Syncrowave 250 when I came across Stubbie's article from way back in 2007:

http://www.diychatroom.com/f18/mille...allation-15306

It was excellent info on almost all I needed to know but I have and one additional requirement: I would like to be able routinely plug/unplug the welder and move it to a construction site.

So, I would need an outlet in both my garage and at the site. I would need a plug at the end of the welder input power, then I would need one plug and one "connector" at the ends of a 6/2 extension cord.

I've been accustomed to just using twist-lock type components for things like this, but they only go up to 50A. I beleive I need components that can take 120A. Or am I mistaken? So what parts am I looking for? Or is this a dream for only the wealthy?

(P.S. Although the welder output can go up to 310A, I will probably never set it to more than 160A at the site. In the garage I will probably never go over 210A.)

Your welder should have a manufacturers tags stating the power requirements.

I have to use #6 wire protected by a 125A breaker. I'm assuming the plugs and receptacles need not handle any more current than the #6 wire, but I can't find any twist-locks that go up that high.

Take a look at Meltric Decontactor connectors. They are specifically intended for these types of applications. They're great. They're also insanely expensive.

Another option is to use Camlock connectors. These are single-pole connectors that are similar to standard welding cable connectors, but are intended for line voltage use. They are common in theatrical lighting and sound work.

Meltric is the clue I needed. Ebay has nearly 200 offerings. Thanks MPoulton.
