I recently bought a used Tecna spot welder but iam unsure how to connect the power supply. The ID plate on the machine says its 415V single phase?? It came without the plug attached but has a large 3 core power supply cable. A quick search on the net suggests you can use 2 phases of a 3 phase supply but my electrician has no experience of this method.
Anyone else come across this before?
Thanks.
