I've used one a lot. You will like the AC or DC Functions and if you need to weld aluminum or stainless the Econotig will do it as long as it doesn't need more than 150 amps.
The newer Welders have more functions that are really handy if you can utilize them enough to justify the expense.

The Econotig only has fixed frequency HF, no phase shift and not remote amperage control, they are all neat options but I can live without them for the cost difference.

spudsnstuff - The OP is asking about the Econo Twin HF and not the Econotig that you reference. They are two different machines and the Econotig does have remote amperage control whereas the Econo Twin HF does not but only remote HF on/off.

I have had one for about 10 yrs now and i use it almost everyday. I usually use it with 7018 1/8 and 3/32... it welds em like a champ all day. I occasionally use it for alum Sheet metal up to 1/8" and that also does well if you can weld alum without pedal. I have never had any problems with it so far. If the one your looking at is in good condition i would say its well worth 650 because no one makes em to last like that anymore

Jg= 1986

I think the price is a bit high, it is a good maching, but at 150 Amps you will be limited on Al. It is what a 1986 mach, and sold for about $900 if I remember correctly.
