    Default mobile TIG

    Would like to run a TIG torch off my Pro 300. Can I tie into my 100' of negative lead without affecting performance? Any suggestions for torch brand? I like a flex head, gas lens, and 1/8 tungsten.

    All you have to do is swap the ground clamp from negative to positive and connect the torch to negative and you are good to go. Your choice for equipment sounds like the same as what I use. I have a Weldcraft flex head I think. It works great for most stuff.

    It works great. I have a feeling long leads may affect Lift-Arc performance. Also, the lift-arc will try to outsmart you if you try to outsmart it. I used to forget the machine had it and would scratch start or if it didn't light off correctly I would immediately stick it and try again and then start a sticking tungsten fight with the machine and the workpiece. Just need to relax, touch it for a moment, pull it off and it fires up great. I run an air-cooled torch through 120 feet each of positive and negative leads. I like the locking swivel head torches over the flex heads. All of the air-cooled torches get stinking hot if you are doing much pipe over 2" Not sure if you really need a gas lens on carbon steel. Can't hurt on stainless.

    Your probably looking for a WP-26FV-25-2, the F is for flex and the V is for valve, the 25 is for 25 foot long cable (you can also get a 12ft or a 50ft) and the last 2 is for a 2 piece cable (power cable and gas hose). If you want a one piece cable then you would replace the 2 with a R but then you need an adapter to hook it up.
