    need help with buying a good multiprocess welder

    Hello..

    I need help selecting which welder to buy. I will be mostly mig ,spray, pulse welding anything from 18 gauge to 1/2 material thickness..Materials being mostly steel and stainless but also bit of aluminum. So I need a good welder I think. I would rather have 1 good machine than 2 or 3. I already own a tig welder but wouldn't mind if the one I buy is also capable of tig. I don't want to spend more than $15,000. Any suggestions? A friend suggested Fronius but I have never even seen one.

    If you want to do aluminum Mig you should have a push/pull gun. The Miller XMT 350 is a proven machine and if you get the MPa version has even more features. Here's a brochure that also mentions 70 series and XR-Aluma feed wire feeders.

    IMO, to "do" aluminum can mean two things. Repair vs fabrication work. Repair work spool gun might be better option. If you rats-nest with a push-pull and in your in a tough location, you then have to have access the machine, so if you have to climb in-n-out of an area that might slow you down. With a spool gun doing repair work, you can fix issues right then and there, such as burn-backs and things like that. For fabrication perhaps a push-pull gun would be better. I don't do either just FYI, but from conversing with others who do, this seems to be a recurring scenario.

    It does depend on how much aluminum is being done and the type of jobs. By the post I was figuring it's for production welding rather than repair or occasional welding. I think there's a typo in the sentence below, maybe meant to say stick welder that was capable of Tig?

    "I do have a tig welder but wouldn't mind if it was also capable of tig."

    I already own a Tig welder but if the welder I buy is capable of tig I would be cool with that.

    I like my MIller XMT.

    You could probably find a used one with a wire feeder AND a push pull cabinet for aluminum and still have enough money for a small car with your $15K budget.

    Personally I would want multiple machines that were optimized for the particular welding function needed. I really like my Trailblazer Pro 350D for stick welding and thick steel MIG welding, but I darn sure wouldn’t want to use it for sheet metal welding or simple projects.

    Of the machines that I currently have, if I could only have one it would be the Syncrowave 250. I’d still prefer multiple ones though.

    With his budget he could easily have 3-4 machines dedicated to separate welding processes. Ask me how I know, LOL.

    Jakedasnake, get yourself two HTP Pro Pulse 300's with water coolers. One Set up for aluminum with a water cooled 501D 500A MIG gun/spool-gun/push-pull gun, the other a regular set-up for solid & cored wire with another 501D water cooled MIG gun. I dont see how you could possibly need more than that, as both would also be 300A stick welders and DC lift-arc TIG. Unless youre like me and need a 400A TIG.

    Re: need help with buying a good multiprocess welder

    So I was building a round liquid tank for a farmer and had to join steel to stainless 12gauge. I tried pulse welding it but couldn't get a good weld with the older 352 Miller invision I used. The puddle was very unstable and ran all over the place but yet I had trouble penetrating. I need a good welder for situations like that. My company is allowing me 15000 to purchase a welder. We already have an older Esab , an older Dynasty Tig, and also a portable trailblazer to clear things up. A lot of the work involves steel up to 1/2 thick but also thin stainless sheetmetals that need to be water tight. Like 35 foot long welds .Too long for tig. So we need a really good pulse,spray machine.

    Re: need help with buying a good multiprocess welder

    Any DC stick machine can do Tig on steel or stainless. Engine drives with a Tig torch are used a lot in the field. 15K could likely buy a couple machines. If I had a 15K budget I'd look at top end machines with lots of local support for them. It's funny because when someone is looking for a good machine to start out with, a common response is buy the best machine you can afford in your budget. Sometimes a used higher end machine is better than a new machine. With 15K you should be able to get high end new with full warranty. See if Miller or Lincoln will send a product specialist to come to your shop to discuss your requirements.

    With the budget the OP has, that is good advice.

    Say no more. Listen to the smoothness (of the arc) and absence of spatter.

    And that is just the 200A machine. The Pro Pulse 300 is a real beast. Peak pulse amps ≈600A on some of the synergic programs. Penetration is not a problem. Just saying.

    I like the idea of a new XMT 350 or 450, with multiple wire feeders and all the bells and whistles.
