Find a metal provider in your area and purchase mild steel materials of the appropriate shape and size and you will be good to go! Jack


Thanks Jack! But, I have seen/heard of folks using bedframes successfully, or so they say. To me it "looks" the same...cuts, grinds, and drills the same, that is.

I hear what you are saying, but I'd recommend that you chat with a certified welder about the issue before you try to weld bed frames. After all, I might be the guy behind you when your s*** tank drops off

Jack is right...forget bed frames for the reasons stated...crystiline metal...aka:...bubbles. Crap metal. You need to mate metal with like metal for reasonable results.

You can even dumpster dive at a LOT of fab shops. Scap is worth ZILCH and I know of several in my area where I can get steel and even some other metals FREEEEE!
The shop I worked in for over a decade throws away any angle, flat bar, round bar... anything shorter than 48" and often pieces that are nearly full length for seemingly no good reason. Worth a shot, for sure man.
I haven't paid for a piece of steel pretty much EVER, I just know where to look.

Yeah, thats the same price as a Hobart 140, and the Hobart is a better machine. I've even seen the 140 on sale before for LESS than $500. Like $479 IIRC. Last time they were on sale a Rural King I think thats what they went for.

For $500, though, you could probably even find a nice lil used Miller.

Well doods, I've heard you all and I do appreciate all of the awesome input! I will review it all again and again.

Thanks also for the intel on dumpster diving those shops. I don't know where you guys are but most dumpsters around me are locked up tight. It's rare that I've found one that likely has what I need that is accessible. But, I will check the local fab shops specifically.

For the budgetary reasons stated above I went with the Lowes purchase of the Lincoln Pro Mig 140. It gets good reviews on multiple sites and will do 5/16" mild steel. I did find a few decent one's on craigslist, Miller and otherwise, mostly otherwise, but since I had that big gift card I had to go there for this purchase. It ended up costing me ~$200 out of pocket. All I need now is some gas!

Check it out!

One question I did think of, which will be painfully obvious to most of you, is whether or not the mig rig I have will be ok for sheet metal. The previous discussion focussed on stick welders, since I brought them up to begin with, which are not ok for sheet metal. Will this mig be too hot for sheet metal?

Cool

According to your trusty Lincoln-Pro-Mig 140 Spec PDF
[ http://www.lincolnelectric.com/asset...480-1/e726.pdf ]

ON the manuals, I don't know which one is yours:
Operators Manuals | Lincoln Electric



you should be alright with welding 24-gauge steel sheet, that is according to some conversion table about 0.025" or 0.635mm - I would hope you have nothing thinner on your BUS!!
[ M E S T E E L ]

Otherwise it is time to break out your trusty OxyAcetylene-equipment OR your TIG-welder!! You don't have either - you better have another gift-certificate for Loewes!!

Please, have a look at your manual according to material and thickness you use different size wire and quality.....

Though it says you DON'T weld 1/4" in one go on gas - have a look at this youtube clip - apparently there is tricks to go with...
[ ]

I wouldn't be surprised if there were some tricks for thinner skin too!!

NOW - it is time to google/youtube/forum your way into the details/mods/tricks of your new toy!!
GO MAD!!

Lincoln itself has at least a weeks worth of stuff for beginners to read up upon!! They have excellent beginners support!

Read/Watch/Listen/TRY - repeat!! ASK/ASK/ASK!!

There is NO stupid questions - (...well, there is ONE - the ONE you DON'T ask!!)....

Learning curve is about 87 steep! Meaning - you should become good in no time!!

HAVE fun!!
