Miller Dynasty 200 DX - What will it do?

admin

I need a stick/tig welder but only have 100 amp service at my older house. Given that, it looks like an inverter may be the way to go. My question is what size material will the Dynasty 200 DX weld in steel and aluminum.  I'm confused by what rated output means: the 200 DX rated output for stick is 130 A at 25.2 V. 60% duty cycle on single phase 230, but shows 200 A for three phase. Does this mean I can't weld up to 200 A on single phase?Thanks, Ren
Reply:Where are you getting your numbers?  My copy of Miller's specifications sheet for the Dynasty 200 Series shows an amperage range in GTAW of 1 - 150A from a 115V input, 1 - 105A for SMAW.  Single-phase 200V - 460V input will provide the full amperage range of 1 - 200A, with the same duty cycle as a 3-phase input.Ignore rated outputs.  They are just to provide a standard base line for comparing different units' outputs, inputs, and duty cycles.  Look at the amperage range available for its capabilities.Last edited by MAC702; 07-16-2006 at 02:20 AM.
Reply:Yup, I've run mine at 200 Amps welding current powered from a 220 Volt single phase supply.Patrick
Reply:Thanks for clearing that up for me. I have another question. Besides using the Dynasty 200 at my house I will need to use it at my farm to weld some 2 3/8 pipe top corral fence around my barn. I know I should probably have a generator/welder but that isn't in the cards so was wondering two things: will the Dynasty stick weld as good or easy as a Bobcat 225 and how far is it practicable to run it on an homemade 230 extension cord?  And does this make sense at all or should I be looking at something else to buy?
Reply:It will be far superior for stick welding than the Bobcat 225.At 100% duty cycle (not likely needed) you can run it with 57 feet of a #10 extension cord.  At 60% duty cycle (still a lot) you can run it from 79 feet of #12.  So for each of those, if you go up a size in wire, you can go a LOT further.Since you will likely not be welding at a 100% duty cycle, make it out of #10 and run in from quite a ways when necessary.  You may want to make a shorter one also, though, for when you don't need to be as far away.  No need to run the current through all that wire when you don't need to, not to mention having to coil it all back up again (NEVER leave it in a coil while in use, of course.)
Reply:I had occasion to weld test: Miller 200,300 Dynasty's, new 200 Syncrowave and the Lincoln Precision Tig 185. Aside from spec sheets I found the Miller machines with their computer based programs all with hidden menues behind the push buttons an operating obstacle and question the usefullness of all the options they have. (Be prepared to do a lot of operating manual reading)The Syncrowave Tig welded Aluminum better right out of the box and Arc started better than the Dynasty (could have been I missed something in the op manuals).  Overall the Lincoln Precision 185 performed as good if not better than the Millers and much much simpler to operate....it does good even with stick 6010. Hey you can always rent a generator for those times when you are out back. Anyway, good luck and recommend getting the rig for the type of welding you will be mostly doing ....possibly rent a unit and try it out first!
