3 Phase vs 1 Phase TIG

admin

Hello Fellas,Is 3 phase 220v TIG welding that much better than 1 phase?I need to change the plug on my welder and would like to increase my options if it would make a difference. Meaning, changing the primary plug on the welder to the highest volts/amps/phase.  Thinking about 220/20/3phase and fab/add pigtails accordingly.Luckily, have access to 3 phase at times.Plan on welding aluminum and titanium in the near future.How much better can we utilize the potential of the machine in sig if we run it on 3 phase?For those of you that have used both phases on the same machine your input would be greatly appreciated.TIA.Dynasty 200 DXMM 211Spectrum 375 X
Reply:3 phase will help especially on the high end of the machineit will be easier on the machine due to the added phases, can you run on 440volt or higher than 220? this would be the absolute best you could getalmost similar to how you can use a dynasty on a 110 circuit and when you go to 220 your opening both circuits of course most of what makes 110 pretty useless is the fact you can only really get 15 amps or less out of it but if you fed the machine 30 amps at 110 it would be much harder on the machine than 15 amps at 220I dont know what your doing with the machine but it can only do so much..
Reply:Thanks BM.I guess what I'm really asking is will 3 phase help in allowing the advanced squarewave circuitry utilize the increased frequency and improve the weldability over only 1 phase.To me, in theory, it should.  But from you guys in the field with the experience of using both, does it make a difference?Have searched and haven't been able to come up with anything that addresses this.Anyone know?  Thanks in advance.Dynasty 200 DXMM 211Spectrum 375 X
Reply:i think a welder set up for 220  or  440 singel    phase  will  not  work  on  3  . phase .   now  a  welder  set  up for  3  phase  220  or  440  may  run  cheaper  on  elect.  power ..  you  can  get  a  outfit  to  and  convert  3  phase  to  singel  phase for  about   $200.  look  and  see  how  machines  you  haveto  see  witch  works  best  overall . best of  luck  ruffisc
Reply:Your primary advantage would be a smoother and cleaner DC arc presuming the machine employs a 3Ø rectifier behind the transformers.Other advantages, lower power draw (amps) mean less cost of wire to the machine.  Also in a commercial power situation your demand charge would be lower on 3Ø which can be a considerable saving on high amperage.  I'm not conversant with the square wave power supply in the machine so it is difficult to say if you'll be able to see any difference in arc quality.
Reply:Thanks fellas for your replies so far.The welder will take and run on anything up to 460v, 3 phase without relinking the power source.  So it's not an issue of taking the cover off, just an issue of $ and time to put a new plug on and make pigtails.  And you know 220v plugs and connectors aint cheap.($75 per connector).Just want to know if it will pay and make a better weld and was hoping to hear it from someone other than the manufacturer.Thanks.  Hope to hear more.Dynasty 200 DXMM 211Spectrum 375 X

Reply:Did a little more digging today.You are right.  Won't make a better weld.Thanks for all your input.Just going to plug her for convenience.Dynasty 200 DXMM 211Spectrum 375 X
