Hi, I recently bought a powcon 300ss arc welder which came with a 16a 5 pin 3 phase plug on it. My workshop only has a 32a socket so I swapped a 32a plug onto the machine. It powers up but when trying to strike an arc it trips the breaker on the wall. Any ideas how to fix this? Do I need some kind of 16a to 32a adaptor? or is it more likely the fault lies with the machine itself.
