Help needed!! just brought a Murex tradesmig 235 at a sale untested, having put it all together earth lead, gas etc, I tried it, motor starts stops ok no overrun on wire feed etc then came to try on some 4mm plate, as I started welding there wasn't much power or penetration on the higher settings and couldn't have the wire feed above setting 2.
I've checked all earth connections, looked inside but couldn't see much that stud out.
I checked the voltage between earth and gun tip and got around 17v on setting 1 and this increased by around 2 volts on the rest of the settings,
I am after a bit of advice on what to check next was going to clean contactor contacts and check voltage across them and check the diodes out but this is about my limit without help, its got new 0.8 wire and a new tip.
It may be a simple board fault it has the W10E PCB fitted, is there anyone out there who can lead me in the right direction or fix this at a good price please PM me any contacts.
