[updated:LAST EDITED ON Oct-18-03 AT 09:25 PM (CST)]Hi, My dad and I are looking into getting a mig welder. So far, after doing some research, we decided that the Millermatic 135 would work out best for us. We figure that for the minor welding and facricating, the 110v will be just right. When we first started looking, it was either between the Lincoln SP-135 plus and the Millermatic 135. We were told the Millermatic was a better quality welder, and we have friends with Miller welders, so we went with their opinions. Has anyone had any experience with any of these welders and would like to give me some opinions. A question I have about the Mig welders...I am just kind of starting to learn about them: The millermatics amperage range is from 30-135 amps. Now, at first I thought that you adjusted the power of the welder by adjusting the amperage, but after looking at the spec sheet, the miller has a voltage knob, not a amperage knob. Can someone explain to me how this works...this is kind of confusing me. Also, from what i have heard, welding with gas is much better than with the flux cored. The bottle either can be filled with straight argon or with a mix of argon/CO2. Can someone explain the difference in welding with the straight or mixed? Thanks for all the help
RE: MIG Welding Questions After doing research for a welder I too settled on Miller and purchased the Millermatic 210 a year and a half ago. Very happy with the price and performance, an all around great machine. As far as voltage / amperage, if you increase voltage through the same resistance doesn't amperage increase? Then if you increase voltage the amperage is increasing. As far as gas I am using the argon / co2 mix and am happy with the results. Pure argon is more expensive, provides deeper penetration and can cause undercutting on steel. Adding the c02 causes the metal to flow better, reduces metal splatter and arc stabilization. I would recommend the mix for welding on old trucks. Good luck with your projects.
