What is the difference between the two models? What does the DX mean?

The 280dx is more feature-rich when it comes to aluminum TIG welding. ► Click here ◄ to download the 280 Series specification sheet from the Miller website.HTP Invertig221 D.V. Water-cooled

OK thanks. Guess I'm getting antsy waiting to see what that 400 amp HTP unit is all about.
Also I've been going over the specs for the Lincoln Aspect 375.Comment

Little birdie that flew by told me the new Invertig 400 will be cheaper than a 280dx. Which makes sense since they need (want) to sell you an American Rotary phase converter with it to get maximum potential. Put an 80/20 Ar/He mix behind it and watch out aluminum of the world!Originally posted by Ferrucci-fabrications View Post
Probably still less expensive than a Dynasty 400 with the phase converter. I'll let you know when mine gets here.
You can get a decent idea by looking at the Stel TIG 453H S.Last edited by OscarJr; 07-20-2019, 01:15 PM.HTP Invertig221 D.V. Water-cooled

Those specs were not on the Stel page last time I looked. Wow! If I read that correctly 350 amps on 1-phase?
400 on 3-phase? Automatically works on 200-575 volts input 1 or 3 phase. Hope it is soon.Last edited by Ferrucci-fabrications; 07-20-2019, 01:44 PM.Comment

Yea, but the little birdie told me the 1-phase power will be limited/de-rated to 300A. Why, I'm not sure. The birdie flew away before I could find out.Originally posted by Ferrucci-fabrications View PostHTP Invertig221 D.V. Water-cooled

No complaints here with my DXComment

The DX has a slot for a chip so you can expand into new programs.
There is also one that you can mig weld with too now. (CC/CV)
I have the DX and we use it the most in our shop. They weld fantastic.

The Miller specs list amp draw a rated outputs but not what it would be at max output.
What size breaker should the Dynasty 280 be fed with on single phase? What breaker or fuse size for 3 phase?
If I were to get one I would probably plug it into 3 phase but nice to know what single phase power would be needed if I took it out to use elsewhere.Comment

The aspect 375 cuts itself off on single phase like the Stel machine does. My dynasty 400 is still a 400 amp machine on single phase where the others are not. I think the duty cycle is like 10% at 400 amps but its still there if you need it. Just have to take your time. I am curious if the HTP will cut itself off on single phass as well?Originally posted by Ferrucci-fabrications View PostDynasty 400 Wireless
