You can use any HF box for your machine. Will need a TIG torch, consumables, Power cable adaptor, Argon gas and a Regulator-flometer. John

it will be a sinewave, and not the preferred squarewave. you can weld with it, but results may not be completely satisfactory todd
Adding the HF to any stick welder would give you the capability of welding with AC for tig BUT even for an experianced tig welder it would not be easy. You would not have a remote current control and would need to compensate for the change in heat buildup with travel speed alone and you would not be able to properly fill the crator (puddle) at the end of the weld.

The HF box that is meant for your welder is the best you can get. Use AC current on the aluminum. With a Lanthanum tungsten.

Face it. A HF box is a HF box, they all will work. Miller makes a goods one also. John
