How many amps

[Jim-TX]

I just don’t want to run out of knob to the right.....because what ever that is I will get out my credit card if that is what it is going to take

Based on virtually no information as per needs, get out the credit card.

On another note bigger is not always better. Connecting our Spool-o-matic 1 with .030 Al wire to the big MP 65E isn't a good thing. Can't turn it down far enough. So we use the gun on a different machine where the low range is more adjustable and user friendly for the gun. Face it welding 10ga steel guards with the 65E and .045 wire isn't very pretty and in this case a smaller machine would work quite well for appearance and in cost.

Keep in mind, MP-65E is a LOT more than a bit bigger, it is about as big as it gets for manual welding. When we say a "bigger machine" something like a Millermatic 212, 252 or even 350 is more along the lines of this particular discussion.

Is it safe to assume the MP 65E is a bigger version of the MP 30 E? We've got a couple of these at work and they are amazing when you can get them running right. (Broken gauges, crappy feeders, knob loose, and so on. Fan died in one, now it sounds like a constapated wookie and just isn't the same anymore. )

200 amps will put you in the ballpark of what a stick welder can do. I have a MM185 and it does okay, but I still fire up the trailblazer for thicker than 1/4" when you really need good penetration. So with that information, I would say 185 amps is just shy of good burning power. I would like to upgrade a wee bit and would like to have the MM251 but I am sure the 210 is a fine machine as well.

Hey Steve do you ever worry about the flammability factor of a fart while welding, especially while wearing coveralls? I know I do. Haven’t blown up yet but it is a real worry, at least I think it is. Any way you make a very valid point about the need for MIG at all. Used to be the exception to use MIG now it seems to be the rule. I like the isolation of having the hood down. Tried wearing it around the house, my wife didn’t think it was a good idea. Sorry a bit off topic.

The Flamability factor of a fart???,,,, Elevendyfour?? You guys are cracken me up!

I hope farts aren't too flammable, or a couple of kids at school are going to end up in emergency severe blast related injuries! (At least I've got a respirator, and there's a big fan in the back room)

Ehhh..hoooo.lay

Tacmig, Here is a good example of what you said. For 6 years I had to repair Al fuel tanks with the spool-o-matic 1 with the 65E. It was a pain in the but. Since my previous job was welding Al with Lincoln 300 Square wave Everyone wondered why I was complaining. Finally the Boss jumped at the Lincoln Square wave 175 for me to use. At 3 bucks per gallon for used tanks I recouped the cost plus in about 3 weeks. Now it takes longer to prep the tanks for welding than the actual welding. Sad news? You bet. They brought me a 1/2 thick Al truck frame part wanting me to tig it with the "new" welder.(135 amp max AC @ 20% duty cycle). Sometimes you can't win. I used Martha and 1/8 Al sticks.

I suck at Al and it's a good thing I hired someone that cranks it out like a machine! In the unfortunate event I do Al (usually grab rail stuff on-site) I use my MM175 with the SM3035 and it turns out pretty darn good. Not like our tigs but pretty good. If you're wondering why I don't tig it, it's because even on a good day I would have to improve just to suck at tig. I'm a mig'er and stick'er

About the farts!

Farts are no laughing matter! The mere thought of someone producing an "air-biscuit" while using O/A is indeed frightening. It is in my opinion that a fart regardless of it's yield should be classified as an IED (improvised explosive device). Hence, providing federal protection in and around ones shop! It is also in my opinion that anyone who knowingly engages in the act or practice of methane production be immediately terminated, reported to homeland security and severely gang slapped!

Just for grins I signed on to check the boards and I saw your post (s) bearing videos of the human posterior blow torches. My God, where is the humanity man? Imagine the aroma? And no back flow preventors! These devices need to be outlawed now!

Ya, when we all have chili for lunch I tell the guys not to fart just anywhere but use the empty cetylene tanks in back. Gas is expensive. I don't remember farting while welding. It would be the third thing. Can only talk and weld, that's two. Can't do three. Welds start downhile when I try. I would think the MP 30E would be 300 amps at 100%. The Mp 65E is 650 amps at 100%. Would have to look that one up to be sure.
