Yes the very one.Can't be much attached to the fuse if it's a 400Ma !
Can you follow the wires that go to/from the fuse holder and post as to where they attach (pcb connector ?)
Is it the fuse indicated in this pic ?
Could well be, the wire feed motor has that 208 number on it as well.24 volts for the wire feed motor ?
Thanks MikeWell I did think weld splatter but could not think how it would get in there !
Transformer should not be an issue to get. Main thing is getting one with same voltage and same rating (VA or wattage) You can go more on the VA/wattage but should have same voltage (AC voltage, 24V ?)
It's doing a similar job to the ones that go on Sips or Clarke machines where theirs are mounted on the pcb
Make sure you mark the wires you disconnect. There will be a pair of wires (one of which comes from the fuse) that are the mains IN to the primary side of transformer and the other pair that are the secondary OUTPUT. it won't matter which way round the IN's go or the OUT's go so long as you don't mix up and in for an out !
