Gentlemen. I recently acquired an old Syncrowave 300 welder at an
auction. It is currently set up for 460 volts single phase. This
setting involves one copper or brass jumper tab that join terminals 3
- 4 of 6.
To change the voltage inputs to 230 volts 3 phase requires 2 jumpers.
One connected to 2 - 3 and another connected to 4 - 5. The normal
protocal is to piggy back two jumpers together when they're not
needed. However, somebody didn't do this and therefore, one jumper is
MIA.
These are simply thin tabs of copper or brass. I'm wondering whether
these are a purpose built Miller item or can be bought from an
electrical house or even custom made.
Anybody have a clue? These are much thinner than the bars used on a
Syncrowave 500. They're just thin sheet material.
TIA
Vernon

Correction. I did not mean to say "3 phase". This is a single phase
welder. It can be set for 208v, 230v, or 460v, and possibly, higher.

there is most likely two jumpers that you see.

Are you 100% sure that they are not, in fact, piggybacked?

Even if they arecustom built, you can likely get one from a Miller
dealer for a few bucks. Or you can make your own.

Easy to get, easy to make, easy to substitute. No problem in any
case.

Just snip off some 10ga wire, strip the ends back, make a loop and put
em under the nuts with a flat washer.

Any welder repair shop will have them on hand.
Every major city has at least one welder repair shop.
