ive got a lincoln procore 100. it runs off the regular 3 prong current and has a gas upgrade kit that i also have. with the gas upgrade it welds from 24 gauge up 12, which is good enough to do the frame rails on a mustang (14 gauge i believe).

the manual also states that you can weld aluminum and stainless with the correct wire and gun tips, but i haven't tried it yet.

 

If you get something with a gas generator, it will definitely weld a lot cleaner and a lot more.

 

this is a good one and will weld just about anything on that car. http://cgi.ebay.com/Hobart-Handler-1...QQcmdZViewItem

 

hi ive been welding for 4 years so far on a lincon electric mig thats 220, it uses a c25 gas tank and recently ive welded in a floor pan/ frame rail and frame rail extension. a mig isnt really that clean of a welder for anything under 1/8 on an inch. it took me so much time to replace the floor pan because i kept burning right through it. a tig is what you really need but those are more expensive and a lot harder to learn. a mig would do fine if you use small welding wire and turn it down real low. it isnt that hard to learn. its kinda like a hot glue gun.

 

ive welded anywhere from 22ga-4" steel with a mig welder and its all in the settings and the welder you have. for thin metal you should have something in the 130 amp area and for thick metal like 1/4"-3/4" around 240amps and higher for thicker stuff.

 

I have a FARMLAND 115 with variable heat and speed settings. I got it at TSC last year 2004 around Christmas time. I think I paid somewhere around $250 for the setup it came with the gas valves and lines. Gas bottle initially was about another $50-60 and it costs about $8 to have it refilled. It did take awhile to figure out the settings for thin sheet metal and I won't say I am an expert but for in my garage on my project not too awfully bad. I can also tell everytime I get past my next section that it is getting easier and the welds are looking better. For mine the settings are low heat (1) and high speed (8). I use a .30 wire feed. The real trick i learned was to make sure everything was really tight to get the best welds.

 

i have a linclon sp110 i love it but a mig can be verry trickey.
first the area you are going to weld on is free of rust and is verry clean.
second when you are trying it out dont get frustrated with it, welding is somthing that is trickey to learn but once you get the hang of it it is verry easy. when you are looking at a welder go to your local welding shop and talk to them and see what they have and the price they want, i know lowes sells linclon welders the 110 welders are a good little rig for dooing patch work and pannles but a 220 can give you more of power for bigger jobs.
now on the subject of aluminum welding that is verry hard to get the hang of,becayse the puddle of alum does not glow like steel does.
i work for a transportation company whitch uses refrigated trailers they all have alum floors i have replaced a lot of flooring over the past 4 years .
we use a linclon power mig 255 with a prince spool gun,i have tried to run alum wire in my 110 and it is not verry easy because the wire is easy to bend and it gets kinked in the gun, the best way to weld alum is with a spool gun whitch holds a 1 pound spool of wire in back of it and pulls it out ,but i dont think you con put one of them on a little buzz box ltik the 110
have funn welding dont be afrade to learn about welding , pluss be careful when you do get a welder of arc burn it hurts bad feels like someone dumped sand in your eyes, i have welded for ten years now and i have arc burn several times, things white like to reflect the around if you get burned dont wory you can slice a patato into thin slices and put them on your eye lids, i know it sounds funney but i works they do have red and yellow blankets you can put up th help shield the rays away sirry this is a long post but it nice to be informed about certin subjects like this.
if you have any more questions you can email me at fireball580@yahoo.com
