Re: welder opinions
You are going to have a real hard time with penetration above about 3/16" with a 110 VAC unit.
Hobart has a 175 amp Job Handler that comes with regulator, and all the hardware for about $550 now.
(Hobart is owned by Miller, so you get all the Miller goodies inside)
It's a 220 VAC unit, but it does a very good job, and you can do 1/4" on a single pass with 0.035" wire and gas.
The good news is it's still truly portable. It's a hand full, but it's light enough you can move it by your self.
They have a free welder cart that holds the gas bottle going on right now, so you might want to look into it.
Hobart also makes a 135 amp Job Handler that is a 110 VAC unit.
It also comes with gas regulator and all the goodies, and I think they may have the cart thing going with those too. Expect about a $450 price tag though, and you can do 3/16", but not in one pass...
Lincoln 130 amp is the thing for body men that work with thin sheet metal all the time.
They have an infinitely adjustable voltage setting, as where Hobart has the presets on the switch type ('Click, Click').
If you are a body man trying to weld on some if this new high tensile strength steel they put in cars now, you will appreciate the voltage control you can achieve. It's just too easy to ruin that thin metal.
If you are a 'Heavy Duty Inventor'... (like most Jeep guys are) the extra power the Hobart provides is what you are looking for.
So, You can do more tricks with a Lincoln, but the Hobart/ Miller will do more work and be less picky about what it will weld.
