I am about to buy a '93 Mack CH613 tractor with an aluminum dump trailer. The trailer will need relining soon. The seller estimates it will cost about $1,000 to have the welding done. He already has the sheet aluminum. I am considering buying a Lincoln SP-175 MIG welder to do the work instead of having it done. There are two versions, the SP-175T and the SP175+. Anyone have experience with this machine? Is the more expensive version worth it? (It has continuous voltage control, but adds about $80 to the price.) Both machines require a $45.00 kit to push the aluminum wire. I have MIG welded steel, but not aluminum. Is it all that hard to learn? Is there a better place to buy than:
The welder plus the consumables will be about the same money as having the welding done, but I get a new (tax deductible) toy! On the plus side, this seller will ship this machine for $7.50! I called to verify this, because it sounded too good to be true. I originally found this welder on Ebay, but this dealer is cheaper, and buying from the dealer guarantees the three year warrantee. Oh, and I already have a spare oxygen bottle that can be swapped for the bottle needed for the MIG. All opinions welcome. Thanks,
