Lincoln 225/125

Anyone have experience with this welder? I've seen the weld process listed as Stick/Tig on some sites, but the Lincoln site lists it as Stick. It has AC, DCNEG and DCPOS settings, the latter 2 normally used for TIG. I know it is a stick welder, but can it be set up as TIG as well? If not, how thin a material can you weld? Any first hand info greatly appreciated. We had a straight 225 when I was growing up, so I'm curious how much functionality the DC settings add.

What exactly is it?

I have a Lincoln Square Wave 175
it is a stick/Tig with built in high freq on the AC setting
Has foot pedal...I can weld thin sheet to thick (1/4"+) with it on tig setting

Air cooled torch....

I would believe it is a stick / tig machine you have as well

Also...you typically tig AC and DC- (DC straight)

As long as a welder has DC output (+-), you can tig(mild steel, stainless, some titanium)....the cheapest DC Buzz box will let you tig from it, you just need gas and an air cooled torch...that's it.........

Here is a link with the description.

http://www.weldingmart.com/Qstore/p000014.htm

Lowes sells this for under $400.00. I don't know much about TIG welding, but want to learn. If I can TIG with this, it is the one I will buy. The ad lists the processes as Stick and Tig. Lincolns site only lists Stick, but since their Tig machines are much more expensive, they probably don't want this to compete. It has both DC positive and negative output, which would allow me to weld aluminum as well.

if it has dc neg and pos output, you are in the hose...but you can't do aluminum with DC

the only choice with this machine for aluminum is...stick welding it...but the rods are $$ and can't do thin stuff

Thanks hoytheld. I don't need to do aluminum anyway. I do want to learn TIG though, so this will be it. Any suggestions on Tig torch setup. Not sure what I'll need.

Yes...just look for an air cooled torch with hose.

What you will need to do is simply, put the unit on DC STRAIGHT (DC-). Attach the stick welding handle (the handle that holds the rod) to the connector on the tig torch. Run a gas line from the regulator to the torch...I use 1/4" polyflow and put polyflow fittings on the tig line and regulator at the bottle

You will need 100% Argon
you will need fill rod as well...such as 309 stainless (will work for stainless or black iron)

something like this:

It says you can do aluminum with DC+...I know this..but it is hard to control...I said earlier you couldn't because if you have never welded aluminum before (tig)...this wouldn't be the way to start...but then again..if you master this way...AC aluminum welding with high freq would be easy!!

My understaning with DC+ you get good cleaning action but not good penetration. With AC you get cleaning on one cycle and pentration on the next so its a combo thing. I won't need to weld Aluminum, but I may learn for fun.

I've been doing more research and the kit I linked seems to be overkill. It has a plug for household 115 that appears to also let you TIG straight from the outlet. Do I need anything other than a Torch, regulator, Argon and connector fittings to make a quick connect for the Torch and the Stick clamp? And of course consumables.
