Tried my sip130 today, little bag noise from the welder tripped the rcd, reset the rcd and changed the 13amp plug fuse. Switch on welder glows red when switched on but nothing else working, removed sides to check for burnt or loose wires all ok. Recently replace the Finder relay, welder worked perfectly afterwards.
I suspect it may be the high/low power switch?
