Tig torch...

I personally have a Lincoln sq175 with an air cooled 17 series torch running a gas lense. It does most things I need to do around my garage. When you get the amps up or weld for long it definitely gets hot. The hose/power cable is stiff and can be a pain sometimes, once it gets warm its like a noodle though. I have a Bernard cooler with a series 20 torch I have not hooked up yet. At my work I use a Lincoln Precision Tig 375 that has the Lincoln hoses on a 20 series torch. The hoses are on the pricey side, but they are so comfortable to weld with. I run higher amps and it never gets to hot. I prefer water cooled, but air cooled torches weld thinner stuff great. If you do get a water cooled make sure you never let it over heat. I checked the water level at work a couple weeks ago and when I opened the bottom cabinet the tig cooler pump came unplugged. After a few second of running high amps I had a smoking power cable/cooler line in my lap. That was a $145 cable.
