Sync 275

[seanpk]

Hi chaps, got his Syncrowave 275, Miller tells me it was made in Italy but did provide me with a limited manual, want to connect the unit to a single phase supply (yes I do have my reasons and know the issues), I'm having trouble locating the voltage switching/jumpers mentioned for other welders in this unit, I can't see anything that looks like the jumpers in images of similiar plants on the web. I have some photos of the internals here - https://www.flickr.com/photos/266963...57672725141922 - can anyone give any pointers? is this like any other standard miller unit? Cheers, Sean

That machine appears to be a single voltage unit - 380v.

No other voltages listed on the name plate.

Are you in Italy and have 50HZ power, cause without changing the primary transformers., its basically a boat anchor.

I'm in the uk, so if Ed is right then the only way to run it on single phase is some sort of phase converter like these - http://stores.ebay.co.uk/drivesdirec...i.html?_fsub=4 ?

I"m not familiar with European electrical symbols, but, the name plate seems to indicate single phase. No convertor would be needed.
