I am new to welding and to this forum. I have acquired a rather old Sealey Supermig 150-5v1. It has been working reasonably OK and my practice skills are improving, except that today the wire speed has stopped being controllable and only runs at (I estimate) the lowest speed.
I have checked the fuse on the PCB and that is OK. I have checked the continuity of the various wires from the connector plug on the PCB.
Any suggestions would be very welcome.
