Has Miller EVER made a Maxtron 450 that didn't support single phase power?
Thanks, W

I've run a MM252 a good bit and thing it's a great machine. Might have the opertunity to buy a MM251.

Can some one point me to a reference of the differences between the two? If not, can some on tell me if the MM251 has "fan on demand" like the 252? e.i. is is silent when...

On my first pass I missed the link. Thanks. W...

Denny,
Thanks for the link. Just what I was looking for! If any one has any tips they want to share (other than use AC w/ HF), I'm all ears.

Can some one point me towards a resource to learn about DCEN tig welding of Aluminum with He shielding. I've bene a little surprised at how hard information is to come by. Cheers, W

Don't have anything to add to the enima stories but hemochromatosis:
You don't get it from exposure to irion. It's a genetic dissorder that causes your liver to retain feretin (iron) at toxically high levels. Takes years for the iron to build up. Symptoms are joint pain, lethargy and irratability....

If you've got the input amps it's very hard to beat the price/ value/ performance of a big old Sync. I'm in the Boston MA area and was able to screw this together off Craigs List and Ebay for less than $1K:
Sync 300 with pulse and post flow
Bernard SS cooler
foot pedal

Yeah fred, I could take or leave a desert truck but you're right about the pics. The fab is out of control. It must be fun to spend your days TIGing pieces fresh of the CNC w/ perfect fit up. Very cool web cite.

dyn88,
that's about what I was thinking as far as the HAZ and diffusing stress over a larger area.

SS is difinately right, what ever they are doing is working because these things see take a beating like you've never seen.

I'm going drop these guys an email because...

thanks bill. I can see now that it's clearly one pass. As for the fit up, this pic looks pretty good:

This is for a desert truck. While I have a good understanding of 4130 properies, aside from the...

The above pic is of 0.120 wall 4130. The shop seems to have the skill and equipment to get really good fit up. Could some one explain the double pass. Why would you want to do this? Isn't more heat bad?...

Pete,
Thanks for the advice. I'll make sure to keep the inner guide stationary. Based on the credetials ofthe previous owner (fabbed for Curtis Craft in the 50-60s, chassis raced at Indy...) I think it's set up right. The key word is "think". While I'm comfortable messing with most...
