Introducing the New Water-Cooled Dynasty® 280 and Maxstar® 280!

[Miller Welders]

We are pleased to introduce the new Dynasty and Maxstar 280 water-cooled models and complete packages. The Dynasty 280 is an AC/DC TIG and Stick power source capable of welding up to 3/8” steel and 3/8” aluminum. The Maxstar 280 is a DC TIG and Stick power source capable of welding up to 3/8” steel. The Dynasty and Maxstar 280 are positioned to fill the gap between the 200A and 350A machines and are an encouraged replacement for the Syncrowave® 250.


All water-cooled models feature an integrated dedicated-use Cooler Power™ receptacle (Cooler Power Supply (CPS)) designed to power and operate the Coolmate™ 1.3. The power switch on the Dynasty and Maxstar activates the receptacle and helps prevent torch failure. Without the CPS, the Coolmate 1.3 would be required to plug into facility 115V power. For a water-cooled solution, TIGRunner™ and complete packages are available for purchase as well as the stand-alone machine.

So from a technical view point there is really nothing special about this CPS, its just a standard 115 VAC receptacle that we'd find on most every welder. Its not simply activated in tig mode, instead its just on when the machine is turned on correct? So we could be stick welding away and the coolmate is turned on.

I would rather have a simple on and off when the machine is turned on. So if I chose to arc weld, I could have my exhaust fan plugged in and working.

cruizer,
Per the request of many industrial customers, we used another fairly common receptacle instead of a standard duplex receptacle (often referred to as a wall outlet). Doing so will help eliminate misuse of the power provided out of the machine. At this time the Cooler is set to run as long as the power-source is turned on. This is to prevent torch failure if someone is switching back and forth between a GTAW (TIG) and a SMAW (Stick) process.

Still not sure why the cooler power supply is more complicated than it should be, why there is a special name for the simple molex " Special" plug to run it, and why its not ran off tig mode instead of all the time cooler (ATTC).

These are some of the questions I get asked.

[Miller Welders]

In the past Miller referred to welders with a receptacle as having "auxiliary power." Because it is designed specifically to power the cooler, we decided upon "CPS." Because the receptacle is able to be controlled through software we wanted to leave the name open for future improvements if we develop a proven method to turn it off when not welding and still prevent torch overheating or failure.

Yeah, that is a problem for me, unless I can override the software. I just want full time power when the machine is turned on. I realize the sleep mode can be adjusted to 1 hour. I just want that water cooler to do the same.

In an earlier post, you said that adapters would be available for my Coolmate 3. Is that still the case?

[cruizer]

Its funny though why the Miller Engineers can't come up with a proper system. Your main competitor, actually competitors have been using a more satisfactory cooler solution for many years. Everybody examines thier competitors machines. Why not come up with something simular. You have a new machine out there, Why step backwards in Technology, oh well, I haven't had the chance to tear into one yet. I usually get a new machine from one of the LWS's and disassemble it to the frame to see what will likely go wrong.

It's pretty clear to me, Cruiser. Since this machine is designed to run off either three phase or single phase 240, with no neutral, the single phase 120 needs to be created internally. Probably limited amperage, just enough to run a circulation motor. Special plug so some idiot doesn't plug a high amp grinder into it, and fry all the electronics.

These same questions have remained largely unanswered since the 280 rollout thread

http://www.millerwelds.com/resources/communities/mboard/showthread.php?32098-Is-the-Miller-Dynasty-280-DX-Available-Now&highlight=280dx

Could we please have somebody with intimate knowledge of this machine answer our questions...?? preferably somebody from the Dyn/Max 280 TECHNICAL Team..
(I had made this request on the old thread to no avail)

it is always murder when nontechnical folks try to address some of these things..
beginning to get frustrating...

A few of us are starting to feel that we are being fed pablum when we are looking at paying for steak...

Never had a problem plugging my high amp grinder into any other tig machine, say for instance my Dynasty350.

[JSFAB]

So, for instance, why don't you buy one of those great machines?

[cruizer]

I get asked questions as to why something works the way it does, and what function does what. What machine I like or don't like. Sort of a independent advisor.. since I've been repairing machines for more than 20 years. If someone wanted a machine and called Miller, well that machine will be the best, same with Lincoln, Victor, ESAB Excetera..... I do know the ones that won't last and why, I know which engine drives to buy and ones to stay away from.

Socket abuse..?????????????????

The Coolmate 1.3 draws 15 amps…. So… would it be safe to assume that the “Cooler Power” outlet can provide at least 15 amps..??

How many amps is it fused for..??

Even if it is powered by an aux inverter to provide the 120vac…. Why would it care what was plugged into it as long as it was below the fused limit..??

Why would it care if it were a grinder, exhaust fan or lamp??

And if I understood the post properly.. the “Cooler Power” outlet is hot any time the welder is turned on… is that correct… ??

You lost me when we got to the part about the outlet being controlled by software..??? Explanation???

it is presently hardwired?? or otherwise coupled to input power by firmware??...
is it dynamicly PC adressable through a port??

Whoops The Coolmate 1.3 draws (6) amp on 115Vac.
There is limited protection with a 10 amp breaker, unsure why Miller wants 15 amps available on a 10 amp breaker

And if I understood the post properly.. the “Cooler Power” outlet is hot any time the welder is turned on… is that correct… ?? Yes

You lost me when we got to the part about the outlet being controlled by software..??? Explanation??? Eventually they are saying as some point they will figure out a better way to control the cooler. They use a sim card for updating and such. most others use ethernet and a laptop, but a sim card is ok.
