I have a pico 140 invertor, I got it second hand a good few years back. It came with welding leads that were thick enough to be heavy, so I assumed it was a decent welder, not a toy.
I pulled it out after not using it for a while (I got a mig welder, and I've been using that), but now the Arc welder seems to be running at close to the top of it's range.
I turned it all the way down to 5 amps and it still ran a 3mm rod, and burned through 2mm thick bar (I know that 2mm is thin, but at 5 amps I would not have expected to be able to run _any_ arc, that should just be for the lift tig.)
It was set on Arc, not on Tig.
Any thoughts? Is this likely to be just the knob, and a simple fix, or has anyone heard of anything similar?
Thanks
Dave
