Don’t want to state the obvious but the relay is in the wrong side off the board

Yes, I did see that! There are only 4 connections - 2 for the coil, and 2 for the On/Off switch contacts, so I don't think it matters that the relay is upside-down!
However, regarding the "always-on" overheat warning light: this implies that the mains wiring has been messed with.
The warning light must have been wrongly connected across the switched AC mains instead of across the thermal cutout.
Post #17 in this thread shows two wire push-on tags at pin CN4, but the photo in Post #11 of this other thread:
shows two push-on tags at pin CN3 not CN4, so something is not correct there....No arc from 'new' Power Craft welder
Hi all, I'm new to the forum, I have a Power Craft combination gas / no gas MIG welder 30-135A.... I bought it possibly 10 years ago but embarrassingly haven't attempted to use it until now (life got in the way of my welding plans, but now I finally have a worthy project!). It's been stored dry...www.mig-welding.co.uk
You will have to trace all the black wires from the mains input cable, through the double-pole On/Off switch, and on to the internal components, including the three push-on tags on the board. Unplug the machine, cut the cable ties that are in the way, and follow the wiring diagram in Post #1 of this thread:

If you click on the diagram it will enlarge. At the top left of the diagram, Live goes from one side the On/Off switch to the rotary power selector switch. It also goes down to the overtemp warning lamp and the overtemp cutout switch. The other ends of both the warning lamp and the cutout switch go to push-on tag CN2.
The diagram shows another component across the mains - it may be the power-on light, or the fan.
Neutral from the main On/Off switch goes to CN3.
The switched output from the relay exits the board at CN4 and goes directly to the lower end of the main
This little beauty, mates got one ,swears by it. I've used his a few times so fits with what I do.
Sealey would be my last choice for me - Clarke would be my choice
