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.
