As far as heavy Tig goes Im pretty much sorted. Only bigger machines I'm wanting to acquire in the future are Dynasty 400s and 800s. My question though is I want to leave my 350LX setup for Tig welding. Im considering looking for something of equally high or higher amperage that I can set up for running Stick and air arc gouging. Im a little stumped on what machines to look for. My only preference is them being 3 phase power at 400volt. I would also like a bigger Mig setup but I am not a fabricator really so unless a demand suddenly opens up in my area for flood welding I am less bother about that as there are so many Mig options. Im in no rush and its not even a budget priority right now. But just thought I would ask what machines people have seen used out there in the world like I have described?Gear: Esab power compact 205 with tbi industries torch BOC Smootharc 185dc tig Miller Syncrowave 350LX
Reply:I'm actually going to buy a 3-Φ/400V stick/gouging machine, but it is not at the power level you're looking for. It's brand new machine from Stel in Italy. The vast majority of their larger machines are 3-Φ/400V.Last edited by Oscar; 06-05-2021 at 11:32 PM.

Reply:Why would somebody buy a 3-phase 400V inerter?Seriously. I think I'd sooner buy a manure-fired, steam-powered, fart-propelled submarine hydraulic chainsaw sharpener from HFT.
You'll definitely be the first on your block, Oscar! You can rig it with your water-cooled stick stinger!Last edited by Kelvin; 06-06-2021 at 06:41 AM.

Reply:I hope that STEL machine is either really special or a really good deal. Transformers can be pretty costly andwill suck up the power savings of inverter machines.Are you going to run this on a rotary phase converter?Miller a/c-d/c Thunderbolt XLMillermatic 180 Purox O/ASmith Littletorch O/AHobart Champion Elite

Reply:Not sure I understand buying a machine, no matter how good it is, that support will probably be hard to get here in the states, but many of the STEL machines come in either a single input power model, 3 phase 400V, or multi voltage models which would not require a transformer to operate in the states.Mike

Reply:I used a 300 amp Hobart for stick and air arc gouging. The welder could run on 240, 400 and 480 volts. The machine did weigh over 200 pounds. Work great . The only problem was arc gouging would start fires 50 foot away. Dave

Reply:My choice would be the Miller XMT 350 multiprocess. 15-450 amps, single phase or three phase power, 208-575 volt input. It will do stick, carbon arc gouging (up to 5/16ths carbons), DC TIG, MIG, Pulse MIG, and flux core (the last three with the addition of a separate wire feeder). It ticks all the boxes for you and it is also blue to match your Syncrowave.
Reply:And if the XMT isn't big enough, step up to a Miller Dimension 650. 15–815 A, 400v/3 phase power. The only thing it lacks is the ability to pulse. I am not sure there is much need for pulse above 300 amps though.
Reply:I don't think gouging with an inverter power supply is a good idea. This stick unit from Lincoln does gouge with impunity. But it is a single phase monster. https://www.lincolnelectric.com/en/products/K1285-16?
Weld like a "WELDOR", not a wel-"DERR"

Reply:Dynasty should not have a problem with air carbon arc gouging. 400 is rated to burn up to 1/4" rod.

Reply:A dedicated gouging machine is less than a circuit board repair for an inverter machine.
Reply:I would think if you are going to gouge with an inverter machine you’ll want be with a warranty. Otherwise look for a used industrial machine the 330 or the Miller deltaweld or shopmate seriesMillermatic 252millermatic 175miller 300 Thunderboltlincoln ranger 250smith torcheslots of bfh'sIf it dont fit get a bigger hammer

Reply:I've seen gouging done with a couple of Miller XMTs daisy-chained up to give 600A ... seemed to work OK, but you couldn't pay me to do that with my equipment.(Then again, not much chance of me owning an inerter, either!)
