Having looked into the technology behind PUK and Orion welders, they broadly seem to be sophisticated 'capacitive discharge welders' and cost more than most hobby jewellers (like me) can afford.
However, there are similar (not the same level of technology, but the same principle) machines available on Ebay sourced from China for around £250. http://www.ebay.co.uk/itm/3011373359...84.m1423.l2649
Has anyone been tempted and tried one of these machines?
