Mehhhh,.....You build enough stuff that you should consider Raggedy's suggestion. I have the version of that Lotos Tig that is AC, and only welds steel, only mine is made by a different Chinee company (Longevity).
I've probably already said it here, but for the price of the Chinee piece VS a reputable US brand, you cannot afford
not to get the bigger machine. I've had my machine since 08, It welds and cuts steel up to 1/2" thick, and I paid a little over 500.00 for it.
The 220v Lotos Mig has a spool gun, and it's what I use to weld aluminum. 1/8" thick aluminum can be done nicely in a fraction of the time that it takes to TIG that junk. It doesn't look as beautiful as a tigged joint, but it's passable, and I'm always about getting stuff to the 80% "passing by Mike's standard". The spool gun hits that mark for the once in a blue moon I weld aluminum.
The way the Chinee machines start the arc is different than a typical DC sq wave TIG. It's more abrupt, and not as "soft" of a start, but you adapt fairly quickly. I have found that it's better to have that thing sitting around rarely used, that not having it and needing it one time.
You really need to go out in your back yard and look under some rocks........You'll be kicking yourself when you buy the basic "TIG only" box for 300.00 when you needed this, and it only costs 162.00 more:

This is the Lotos version of what I've had sitting in my garage for almost 10 years now.
