From the horses mouth:

This is a good to excellent condition Lincoln Square Wave TIG-355 heliarc welder. This welder runs off of 220V single phase power and requires a 100A circuit. Also includes torch, torch cooler, and pedal. No helmets or tanks are included. XS Engineering recently upgraded to all Miller welding equipment and no longer has a need for this heliarc machine. This machine can handle aluminum, steel, stainless steel, titanium, or anything else you can throw a rod at. AC/DC output with pulsed output and has all the bells and whistles. This machine has not been used in 2 years and was only used for light fabrication before this. It seriously works as good as new. This machine was over $8000 brand new without accessories back in 1999, but it's yours today for only $2500 plus shipping. Obviously this welder must be shipped by truck freight.
