A friend of mine wants to restore an old car that has a lot of body rust and asked me about the best type of welder to use. I told him I didn't have a clue, but knew lots of people (who know what they are doing) that I could ask.
Keep in mind, he has never welded before (but is very determined and picks up things quickly) and will be doing mainly body (sheet metal) welding. Any suggestions on brands of welders and the best places to buy would be welcome as well. Thanks in advance for your help. -Don |

The enemy of a good weld is oxygen. When the inert gas flows out of the welding nozzle it creates a curtain of oxygen free gas that allows a strong weld. You can use a MIG machine that uses "flux wire" with out inert gas shielding. These machines are usually a bit cheaper but they do not work all that great. A true Mixed Gas Arc Welder does a much better job.

Don't be tempted to buy a cheap MIG as that's all you are getting,the wire feeder and electronics (burn back control ) usually crap out quickly . Anyone can learn to use these but often forgotten is the need to have good clean steel and only tack large sections in bit by bit to reduce heat build- up and distortion. All brands mentioned are great,the Hobart is good value,I used a european ASAB on a restore but not sure if you can them in the US. When I was shop engineering we had the larger Millers ,if well maintained they seemed to go for ever,great parts backup too. |
