Not sure what that means?Polarity error?

Yes - gas is coming through fine.This^
All the advice given is good advice, but none of it is helping you diagnose the problem. Hold the gun next to your nose an press the trigger - do you get a woosh of gas???
Once the wire has been opened it's exposed to the air. After ten years it's bound to have some rust. Good luck.Thanks - will do - It is ten years old but I have only used it once?
Yes, exactly that. 50v DC range, one probe on the tip, the other on the return clamp. The data plate will tell you what range of voltages to expect.What is the procedure for measuring voltage without welding your meter to the bench?
Gas off, feed off and just probe between tip and earth?
<edit> also what would happen if there was a break or ultra thin wear in the liner and the wire is shorted out before it gets to the tip?
Not on the TE unless it's been butchered, they're gas only machines.Polarity error?
Some liners are plastic, or steel with a thin plastic sleeve. Others are all-steel ( "curtain-wire" ). Either way, there is nothing in the torch umbilical that the MIG wire could short to. This would have to be the other side of the main DC welding power output, and that does not go to the torch assembly, it goes to the work return cable & clamp.also what would happen if there was a break or ultra thin wear in the liner and the wire is shorted out before it gets to the tip?
Polarity refers to the MIG torch being positive with respect to the work clamp for solid wire with shielding gas, and negative when a machine is configured for use with gasless flux-core wire. However, even if your welder had this option and it was set incorrectly, it would not cause the effect you are seeing.Not sure what that means?

dirt on the wire so will cause slipping if you havent used it in a whileI have this issue with mine but only when I’ve been using the welder for a while at first it’s ok then it will start burning back to the tip even though the settings are all the same, weird.
