Tig welders - discuss

I have been TIG welding for years both on the job and at home. I have a Lincoln square wave 175 for the house and it does everything I need it for. Like everything it takes practice, be patient, you will get the hang of it. As far as welding aluminum, it's a completely different beast than mild steel or moly.

I second this. I've had my square wave tig 175 for about 18 years and it has done everything I have wanted to do. My personal experience with welders is you get what you pay for. I've got this and a powermig 255 mig welder. Happy with both. I was able to build a very nice set of headers with the square wave tig 175 machine.
