Ive said it before and Ill say it again...a welding machine is NOT an area you can cut corners!!! If youre going to buy one, save yourself a lotta headaches and buy a good one. If you cant afford a good one right now, then dont buy one until you CAN afford a good one. You can find a decent machine for $500-700 to do anything automotive, but if you try to save a few bucks by buying a cheap one, youll just be asking for problems down the road.
