    Starting out

    Thanks Hank; at least I feel that I can get a start and perhaps develop some technique. I have a welding class after the 1st of the year and I want to be able to practice. Your certainly right about cost, I got Argon the other day and a tank about the size of a dive tank was $100 for the tank and $13 for the gas. I had hoped to get going for under $500. but I don't think so now . Even with the cheaper welder it looks closer to $800. It cost me $100 just to run a 220v circuit to the shop. It's like everything else if you can't pay, you can't play.

    Cap'n B.,

    You probably won't have much luck on aluminim thicker than .125", but that machine will get you broken-in on mild steel just fine. It'll do well on sheet goods, and using multi-pass technique, will be adequate on .250 steel with proper joint prep.

    Now, you need all the acutrements: shelding gas (or gasses, depending), grinders, helmet, et. al. I'd recommend 100% CO2 for your steel work. It's cheap, and it provides better penetration than C-25. For aluminum, you'll need 100% argon. By the time you are ready to go, you'll have more bucks tied up in gas bottles and regulators/flowmeters than you do in the welder!

    Good luck, and enjoy.

    Hank

    New to MIG welding, chapter 2

    New ball game now. Taking your comments as much to heart as I could afford to, I was able to trade up without any extra cost to a Dual MIG 151T. Basically the same as the last machine except it is 120amp / 230v so we increased the power to what everyone seemed to say was really needed. I still could not afford to get up to the Miller or Hobart machines but I hope this Harbor machine will perform well enough to at least get me started in MIG welding.
