Default New welder

Just picked this up after shopping for a couple of months. Miller XMT304 300 amp multi process with an S22a Wire feeder and air cooled gun. I already had the water cooled gun and a spool gun to go with it. Now I just need to make a cart to hold everything.

Nice machine! The spool guns make quick work with aluminum, and that machine can handle it!

I'm hoping I can master the spray transfer welds with a spool gun and drop the water cooled TIG process for AL altogether. It has always been a royal PITA. Loose coolant flow for a few minutes, and the TIG power cable just melts down. Not to mention how much I love welding w/ a 220 VAC machine and discovering I'm standing in a puddle of water.

My hope is I can master MIG on AL, do only occasional TIG on steel and do all of it using air cooled processes.

I've migged Al afew times and once you have it setup it works pretty easily. I agree that setting the TIG on nuclear to do Al can be annoying... especially for those of us with air cooled torches.

I honestly only TIG the small steel stuff now, I almost always use my mig if I can. That;s a sweet rig though, I wish I could run 300 amps for aluminum.. it seems like a nice number. My machine goes to 225 and that's barely enough for the thicker stuff.

I am so happy to hear someone else besides me thinks this way... my wire feed won't take a spool gun and it's probably the thing that I regret the most about staying at the level of mig I did. I could never justify the cost of a bigger machine (or find a steal on one) to pull the trigger. I went air cooled on tig strictly because of the torch issue, plus I don't do above 200 on al very often, though I probably would if I had it lol!

good choices all that you've made there, except for the color of the equipment, but hey, to each his own.

I still stick my thick steel by the way, I like the challenge of making smaw looking like tig.

I think we need a weld school pizza party. I got a Ready Welder & haven't had any time to figure out the dang thing. Probably won't either til I get moved in. John & Marco - you up for that?

A weld school would be the shiznit, I've never had a class and it shows. That's why I TIG & MIG, I just don't have the skills to make a stick weld look good. One of my best friends has been welding since he was a kid in his dad's body shop (now 60+ years old) and his stick welds are are work of art. I'd kill to be able to do that.

BTW, I just got a Optima Pulse controller to go with this setup so now have yet another toy to learn this long weekend...

one thing I learned about stick, is that it's all in the thickness of the base material and the prep. oh, and the rod. yeah, then there's that amperage/polarity thing... lol

I did strictly stick welding for about 5 years in an industrial setting. I got OK, but it was all learning through trial and error... I wasn't doing any thing critical, just laying floors in box trucks, building bumpers, and fixing produce racks.

I've never had a formal class though, so all i know for TIG and MIG is from an apprenticeship I had for a while (10 years with an old timer).. it's all probably been taught to me wrong.

I think John would be the better teacher Anybody is welcome to come by and play with my machines though. I don't have a foot pedal or thumb control on my TIG though so it makes learning hard.
