    Welcome to the forum, one of the most popular methods for replacing liners is to use the steel curtain wire and just cut it to the length of the old liner.

    I am no expert on mig's but as far as I know the basic machines are, I have used curtain wire on two of mine and also done friends machines for them.

    I pulled the old nylon black liner out tonight and its diameter is 4 mm with a hole big enough to take .8 and .6 wire.
    I have put a length of curtain plastic coated wire in as a replacement. Thè dimensions were the same.the wire is now in and the feed is running perfectly.
    All i need now is a regulator and a kit to change over to 4mm gas feed. Then i can get the 180 going.and do some welding.

    After getting the machine set up with gas.i switched it on . The power light was flickering and then went out then i switched it back on again and power light stayed on ..so pulled the trigger to weld gas was coming through.but the wire feed roller stopped spinning completely .could the problem be the curtain wire liner i fitted might be causing a short circuit .? Im baffled because yesterday the wire feed was good. Any advice would be gratefully received

    The liner should not be the cause. Does the machine have a Euro type torch (one that can be disconnected from the machine ) see image at bottom of this page http://www.weldequip.com/mig-type15-torch.htm. If it does then you can cut weld wire just before the feed rollers. Keep hold of the end of wire to stop it unspooling from the reel and secure it to spool. Now remove torch and set aside. With machine turned on short the two small holes on the torch SOCKET using a paper clip or length of wire. This should make the machine run the feed motor. If it runs ok then there is an issue with your torch. If it still does not run the feed roller then the fault is internal to the machine (maybe the relay n pcb) All this only applies if t is a Euro torch.
    If not a Euro torch then the "fixed" type torch fitted mry have an issue with the trigger / wiring inside torch. You would need a meter to check operation. If the trigger is feeding a signal into the machine then issue could be the pcb (relay on it). post pics of pcb to allow further guidance.
