get a used one at a pawn shop the biggest one you can get as long as it looks like new and its a miller or lincoln 110's are fine but a 220v will last longer and do anything you'll ever need out of it... a good used one runs 800.00 and a 110 ,400.00 with every thing plus gas in the tank......no gas no buy ....just saw one the other day looked brand new... plug it in and weld ...complete...400.00 listen to these guys and dont ever weld a frame with a 110v welder it'll even give a pro trouble no pros will waste thier time doing it ...yes ...it can be done ...but they wont.. they know...betterk.c. said:What would be smallest amperage Mig welder for the garage?

Henry Highrise said:A good welder will last a lifetime and will be used for many different things after you get one, so it seems rather silly to me to even think about getting a smaller machine and then be limited to what you can do.
NEW INTERIORS said:Yes!!! Your right, it can be done...But who want's to be pre-heating a frame butt to 400* ... ain:That will sure do a frame some good... ain: If you do pre-heat,''make sure you weld the frame to a very good jig''... :mwink:
So if they go out in buy a 110 unit,They also need to by a torch to go with it..oldred said:Exactly my point, it can be done BUT is it worth the effort? If all someone has is a 110, and this does happen occasionally, then there really is no limit to how thick a weld can be made with a 110 but the question is how practical would it be? With proper preheat there is no real problem with the actual weld made by the 110 machine but as was pointed out just how practical is it to preheat and maintain heat when welding a frame? The problem only gets worse as the metal gets thicker. Add to that the time spent waiting on the machine to cool to prevent exceeding the duty cycle and the advantage of the 220 is all too clear. For the occasional heavy (comparatively heavy anyway) weld then a 110 machine can be used but the extra procedure required makes it impractical for anything major.
Ahhhh....penitration, the more the better i say :mwink: but I'm listining to what the big red one has to say he's the pimp here.you need a hot rod for good penitration. not a quick lick.1meancuda said:I have a 110v unit for sheetmetal and a 220v arc for anything 1/4" and up. My point was simply this. If you can use the 110v unit and get good penetration on 7ga, then why can't you use it on a frame that is 7ga? Does the metal care what it's being welded with? Please don't take my initial post as advocating using the wrong tool, I am simply asking a question as a beginning welder.
