Miller Dynasty 200 DX Question

[minus32]

I am looking at purchasing a Miller Dynasty DX but before I do that I would like to know what my limitations to certain types of welding. I will be using 110 out of my one car residential garage and would like to know what that limits me to such as for welding aluminum. Some say the most I would be able to weld is .25 in thick before the 20amp breaker goes. Can anyone help with this?

Thanks
Jim

minus32,

WELCOME TO THE FORUM AND GOOD QUESTION.

Your expectation for .250" is the maximum this machine is capable of on a 220 VAC circuit running argon for a shielding gas. The addition of 25%-75% helium will boost your welding capacity on aluminum, but .250" is realistically pushing the Dynasty 200DX. It will do 3/16" and down with no trouble at all on a 220 VAC 30 amp circuit.

You may get as much as .188 or steel on aluminum with 120 VAC 20 amp circuit. Several forum members have reported 180 amps + running on a 120 VAC input supply circuit.

The actual factory ratings are closer to 100 amps at 100% duty cyle with a 120 VAC 20 amp circuit which will weld .125" plate no problem with a slightly lesser duty cycle. There is also a factory rating for 140 amps at 40% duty cycle with 120 VAC input on a 30 amp circuit.

An unpublished factory number is 190 VAC is required to push the machine to full ouput potential. I have personally seen a Dynasty 200 run 200 amps on a 120 VAC input circuit. However, this is the exception rather than the rule. The input circuit was a leg pulled from a 60 amp 240 VAC circuit on 6 gauge hard copper wire at a run distance of less than 75'.

With all this being said I believe you can realistically expect 150 amps on 120 VAC 20 circuit. Keep in mind these ratings are for TIG welding not STICK welding. The output on stick will be considerably less without a 220 VAC circuit.

i believe blownS-10 ran his on 120V for a wile and may still be. i'm shoure he will give you some ideals of what to expect . if i remember right he read 190A on his 120V circiuit.
you might look into the option of runing an extention cord off youre dryer plug if the laundry room is close enough to your garage.

Thanks alot for you input guys, I appeiciate the time to reply. All this will go into what I purchase.
Just trying to get all the facts before I spend 3grand.

minus32,

If you what a TIG/SMAW welder that rocks on 120 VAC with a 20 amp circuit the Dynsty 200DX is as good as it gets. You can take a look at the Thermal Arc 190 and see what you think. I believe you will find the Dynasty suits your needs better.

I'm with Hawk on the Dynasty! I have run mine on 120 and have been as happy with the performance as if it were on 220. The ability to taylor the arc to your needs can make up for some upper end issues if you spend a lot of time up there. Good Luck, JEFF

HAWK is right. i test ran mine on a 120v 20a dryer outlet, 6' away from the breaker box. i got it to 179a dc, i held it there for about 20 seconds or so. no welding was done, just a good arc on a heavy metal part. it melted it REAL good. i have done no aluminum testing such as this. currently, i am running it on 240v. the other day i welded a 1" solid aluminum bar, on the end of a 3/4" flat bar with relative easy. not full penetration, but it wasn't needed. just good solid strong beads. so, when it is said that it will not weld over .250", what they mean is, it will not get "full" penetration much beyond that. but IT WILL weld larger than that together.

nearly every time i use this machine, i grow more & more HAPPY that i bought it

[minus32]

Hawk and all you guys thanks for all the info. Everything you guys tell me is helping my decision and making me more knowledgeable. You can bet your butt when I get this welder soon there will be many more questions to follow.

Thanks again for your time guys.

atached are some pic's
you can e-mail me at [email protected]

ya that about sucks with the heater and all. Well I have a pretty good deal at a local dealer for the contractor kit with the foot pedal but I have not purchased it yet.(trying to get the $$$$ for all of it) so what would you want for all of it and what type of torch and accessories are they?

[HAWK]

fun4now,

I am very sorry to hear about your heater. That is a very nice looking set up for the Dynasty. Send me an email on what you want for it and I'll pass the word around. You might want to start a new thread lsiting your equipment and email address in addition to posting it here. [email protected]
