Hello all! I'm a long time welder, first time poster, although I've used the site before for tips etc. I've had a bit of a look through the old posts and as this is such a common problem I realise I am likely to have missed a relevant post, so I apologise if I'm in old ground! I have an SIP 130T MIG welder with a wire feed issue, no surprises there by the looks of it! I have already added a reinforcing plate a long time ago to help the roller stay vaguely in line, although I'm now wondering if it would help to replace the rollers themselves or if this akin to putting an elasto-plast on a broken arm? I have found these on ebay and wondered if anyone had found that they make a difference? - http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=290841614484 Ideally I would obviously replace the welder I know, but £11 is a lot more manageable than £500+, but even then I don't want to spend money without good cause if it will mean changing the rollers and making 0% difference! I curse 'Practical Classics' for recommending that we all buy SIP 130's all those years ago!
