Welding Tips and Tricks

Hello, I am getting ready to order a Miller 250 DX Tig machine and there are (2) options for input voltages.

Model 951117 has (3) input voltages : 200v, 230v, 460v

Model 951118 has (3) input voltages : 230v, 460v, 575v

I am in California and the voltage in my shop is 240v - but I could move in the future - staying in the US.

Since they both have 230v and 460v, the difference is the 951117 will do 200v and the 951118 will do 575v. Which of these (2) voltages would be better to have?

Thanks!

Is that an older machine? The Dynasty is a 210 or 280 model. The second setup shows 3-phase power ranges whereas the 210 will also run on 120 in a pinch. 280 is only 240 or greater.

It a new machine - holding off on ordering until I figure out if having 200v or 575v would be a better option to have in the future. They both do 230 and 460 volts. model 951117 and 951118

It is a Syncrowave 250 DX

Thanks, Ken

Ah, right. Forgot about that model

You would be hard pressed to find any place in the US that still has 575v. It was used a lot in the south for large motors in textile mills, but that's sort of gone the way of the goony bird. It was also used on farms for large motors. 208v 3 phase is very common in the US and 200v is sometimes the way it is listed on equipment because that's the utilization voltage rather than the distribution voltage. I'm not sure why a welder wouldn't just list 208 instead of 200, probably historical. So you'd be far better off with the 200v version.

Thanks Mark - I ordered the 200v model. I think the 575v is more for Canada.

Now I just need to get the subpanel installed in the garage..

I've been an electrician in VT for 48 years. I've never seen 575 Volt power supply.

Thanks, yea I have never seen 575v either. I bought the 200/230/460v model. They deliver it tomorrow : )
