need a welder

[68 Satellite]

It looks like I'll be needing a welder to do some patch work on the 68. Years ago I used a Miller and thought it worked great so will probably go will one of there's. I have been looking on ebay and don't know if I need a 140 mig that works on 110 or get a 180 model that takes 220. I have 220 in the shop so thats no problem and they are similar in price but don't know which to buy as I'll mostly be welding sheet metal, any suggestions? what do you guys use? thanks

Whatever welder you decide to get, be sure to use .023" solid wire with a tri-mix gas or straight CO2 gas on sheetmetal. Do NOT use the flux core wire, you'll just end up with a mess that'll take LOTS of time to get right. And, especially for sheetmetal, make sure the metal is squeaky clean before you start welding. You do not want any impurities contaminating your welds or causing pin holes.

For sheetmetal only, a 110v machine will do a decent job. If you ever plan on using it for things like trailer hitches, building small trailers, frame work, or things like that, the 220v machine may suit you better.

I had a Hobart Handler 110v machine that worked VERY well for sheetmetal and small repairs. If you do go with a 110v machine, make sure the circut carrying it in your garage is at least 40 amp rated.

I'll second the Hobart. I had a Hobart 90 years ago and it did everything I needed it to do. I fabbed a boat trailer out of 3/16" rectangular tubing (wasn't my idea to go that thick) and I did it in a couple of passes. 1/8" and under it was perfect. I now have a Miller Dynasty TIG and I love it. Not as quick as a MIG, but for heat control it's great. The TIG doubles as a stick welder and for repairs on somewhat dirty and rusty metal, thin 6013 rod is a good alternative. Like the above post says - clean, clean, clean plus I will add rust free from both sides!

well the 140 110 volt would do for 90 % of what I'll do but will probably go with the 180.I suppose if I have a heavier model I may do some fabrication of some type who knows?
