Hi all, my dad purchased the above welder many years ago and we are just looking at it. It is currently fitted with a 240V 32A plug (the blue one) but will not work. Can anyone tell me how this welder is converted to run on 240V? There look like the option under the F.A.R.T. (yes that's its genuine name) cover to switch 240 / 440 but this had no effect on the welder (that currently doesn't work) - do I need to move the wires on the visible transformer on top that has 220 / 415 / etc marked on it. Hope you can help me.
