OK, thats what I thought, so even if I go gasless for a while I won't be suffering any worse than I was arc welding.
MIG welding question for the experts

I AGREE FULLY! Nakman, tell me your brand and a case of it
will be provided at CM, plus anytime you need welding you just come on by. 
Thanks

So, if I"m following this thread correctly; Nakman's new welder is not heading north from my garage but it heading south to become Randy's old welder...

I have not tried it yet but can I hook up my powertank to run CO2? Special regulator required? I've been running the standard 25/75 mix with my Miller 211 so far.
Randy, what's stopping you from getting a bottle right away?

Nothing, I just wanted to make sure it was really worth it. I'm so used to arc welding with stick I thought welding with flux core wire might be about the same.
got it makes sense. Once you get a bottle I bet you never go without though.

You're probably right. Another question: I got the plasma cutter hooked up and functioning last night. I know when I've used oxy/acet torches in the past to cut you angle the torch slightly into the direction of cut and "push" the puddle forward. Do you do it the same way with the plasma, or do you "drag" the puddle or maybe it doesn't make any difference?
I have a love hate relationship with my plasma cutter. Unless you leave your plasma hooked up all the time, I find it easier to just whip out the oxy/fuel and be done with it. That aside, it depends on amperage/thickness.
On thick stuff, I undercut slightly. On thin, I stay vertical. I always use a drag or pull motion with my arm, never pushing. I find that you get less variations. You can usually drag your tip at less than 30a anyway. you should have little to NO puddle with plasma. If your building a puddle on plasma, your moving too slow or not using the right amperage for that thickness
Big tip: If you have the option, get the "art metal" or "fine" tip, whatever the mfg calls yours. the small kerf makes ALL the difference imho.

I used it today to cut the brake backing plate off of a mini truck axle. Thats fairly thick material and it cut through it like it was a paper. I used the same technique I used with the oxy torch and it worked fine. Thanks for the tips.

Thanks
Randy as long as it's cold I'm happy man.. it's all good looking forward to sharing a few out at BFE again.

Me too, consider it done!
