Dont know about that model.
But I have the 180amp version.
Fantastic piece of kit, have been abusing it for 5 years and still works perfectly.
As said above very smooooth.
I run workshops in the sculpture thing, and have had two customers run off and buy Butters welders.
Reccomended.
Chunko'.
I believe they were made in Europe, they're certainly not British or Chinese.
It's a shame Butters went belly up as they sold decent machines and were a superb company in regards to aftersales.
Another company rose from the ashes but they sell different machines to those ones.
If it's for sale at the right price and is in good, clean condition you certainly won't be disappointed with it.
