I'm looking for a used mig welder and compressor. If anyone knows of one for sale, email me. 110 is what I need, but may take a 220 if price is right. Also, who else besides AirLiquide and Praxair sells them.
Besides those two companies, im not sure. I DO know that Canadian tire sells small stick welders for $100, and Lincoln Electric MIG's for $200 something. My father bought me a 110V Lincoln Electric stick welder from AirLiquide for $100 something. I have been having fun with it. It doesnt do too well with the real thin stuff like a MIG does, but I have been surprised with how well it welds the thick stuff. I just did some work today on my fathers bush-hog. Its pretty thick metal but the little bugger did the job so far.
As you said, sticks don't work on thin stock. The cheapest "good" welder is 800$ for a Miller 135 or Lincoln 135. I'm looking for one like that, a Pac 10 - 135 type. I have seen fellas selling used ones, when they up grade. There is CTC and Hub city, but they sell retails not company level. Yes I take a Pac 10 a retail level one, until I can buy a better one. The Pac 10, SP100, Miller 90s, etc are made with ceramic and copper coils. SP 135s and up are made with Alum and Steel inners. They will last longer for the money.
Same goes for the compressor, I could pay 1000$ to replace 2 rocers and a side panel. And get nothing out of it. Or I could pay 500-1000 for both and get the job and the tools.
NAPA can get welders in. We had them on special but I don't think they are any more, you'd have to call and ask for Justin, he would know. The Lincoln 135T we had just sold two days ago, with a $100 cart for $750.
