cheers for that mate what ill do is take some pictures of the liner as to what size etc and if you could point me to the correct one to buy ill purchase a new one mate and thank u for your help .
This info may help https://www.mig-welding.co.uk/sip-wirefeed.htm But note that is for a SIP (hobby type) machine so there is no need to strip the torch handle.
ebay search for "mig welder liner" results. https://www.ebay.co.uk/sch/i.html?_...der+liner.TRS0&_nkw=mig+welder+liner&_sacat=0
You probable need the first one on the lst one type. A liner is just like stiff net curtain wire ! (and some do use curtain wire especially on the smaller hobby machines as they can have a smaller diameter torch lead.
ps if you are new to mig welding then it is worth reading the tutorials on the home page.
