Do I really want an arc welder?

I'm new to welding... I've seen what appears to be a good deal on an arc welder (120/230 V 65/95 A) but I'm not sure if its right for me....

I would mostly weld aluminum to aluminum or aluminum to steel (if possible). It would generally involve thinner pieces/tubing or sheet metal and occasionally larger extruded aluminum parts. Is an arc welder what I'm really looking for? I thought so, but upon reading some threads in this forum I'm thinking maybe I'm supposed to get a MIG.... Does it matter for occasional hobby welding?

Robot Guy,

Aluminum cannot be welded to steel, only itself.

A TIG unit is the best unit to weld aluminum, a mig would come in second but may be a better all purpose unit for home use.

You would need a mig that can use shielding gas. You then would need two different gasses, one for steel and one for aluminum along with a liner and roller kit for the softer aluminum wire.
