Well whilst welding up some plant supports this afternoon the earth clamp parted company with the cable, right at the bolt. Original clamp, I guess it's had a good innings. If I'm reconnecting it is it worth swapping it for something like this https://www.ebay.co.uk/itm/400a-400...-Plasma-New-/321749179766?hash=item4ae9bedd76 ?? Also after having a few feed issues and a bit of searching on here I bought a length of curtain wire to replace the liner. The old one's been in there donkey years. Any advice as far as changing the liner goes? Not something I've attempted before.
