Clearing the air on a statement posted on this site in another thread.

[GUNNER]

As everyone here is aware I now own a Dynasty 350 because my 250EXT couldn't be repaired in a timely fashion. I wouldn't hesitate to own another Everlast EXT250 once the issues get straitened out . That's not the purpose for this thread but I feel that should be said before my fan club starts attacking like Cujo !

The purpose of this thread is to clear up statements made about the Dynasty that I have come to discover are completely false and could effect someone's decision about a Dynasty machine.

I have an account on the Miller site and went there to ask a question about something I had noticed my machine doing and I wasn't sure it was right or possibly it had an issue. The result was it's doing exactly what it's designed to do so that wasn't a problem.. While there I inquired about running my machine on the Rotary converter and if it was a problem. I didn't want to say I was running it on one so I posted the question like I was inquiring... What I found out has made me decide to put it back on single phase and leave the converter running my other 3 phase equipment..Here's what I discovered..

As posted here before it has been though that the Dynasty couldn't reach it's full amps on single phase power and in fact Miller's web page is worded in such a way that it appears that in won't reach it's max amps on 3 phase... THIS IS 100% INCORRECT ! This machine will in fact reach it's full AMPs on single phase! The only issue is with duty cycle on single phase! There had been other Dynasty owners that have asked that same question before and they directed me to the threads from the past that covered this question. So I'm here to speak for the Dynasty once more and let it be known that the information posted about it not reaching max amps is false.. I checked this with a clamp meter today just to be 100% sure of the results.

Also it was posted here by another member about a problem with the Dynasty and it's High Freq start cycle.. That information had some weight behind it because the original Dynasty 300's did indeed have some issues that are posted on their site for everyone to read. Miller did address this issue in later updates and it's no longer there. My machine starts like a lightning strike on an old tree stump on top of a mountain!

In another thread posted there I spoke of my experience with Everlast and the 250EXT and it's there for anyone to read. Some might be surprised after reading it. My opinion about the Dynasty is still the same. It does things better and is more refined on every detail. However I have never posted lies on any forum I belong to and I belong to several. I'm Gunner everywhere I post and I'm easy to find. Like here I have fan clubs all over the place because most people can't deal with the truth because in many cases it exposes them in one way or another. Life is short and everyone makes mistakes myself included. I have always owned my mistakes when I discover that I have have made one. I don't make it easy for anyone to prove me wrong and if they do they have done their homework and deserve the victory. However in the case of the Dynasty not producing FULL POWER on single phase I previously agreed with that statement because I couldn't prove other wise until now. With that said sometimes I'm the one that discovers that I WAS WRONG and sets the record strait! I WAS WRONG WHEN I STATED THE Dynasty COULDN'T REACH FULL AMPS ON SINGLE PHASE !! I stand corrected and apologize for passing incorrect information !

[Cippee]

I'm guilty of spreading incorrect information sorry. What is the max pulse rate on the dynasty? I see it has up to 400hz ac frequency. I could only imagine what that sounds like. When I turn my 250ex up to 250hz it screams like a caged chicken. I have only used it that high to mess around and get into a corner once but it screams.

Ok I get the hint.

I don't know that answer to be honest. I haven't seen the need to even check it but I will and post what I find.. I'm sure Ken will post about how my answer is wrong but I'll post it anyway.. The can't be good without evil. There can't be correct information without incorrect information either. So in a way people like that are required so both sides of anything can be seen. The 100% correct and the 100% abstract ! LOL

[Cippee]

Yeah 250hz is really unnecessary so 400hz is just crazy. I bet if you do test 400hz your ears will be screaming at you to stop. 120hz seams the be about right for most of what I do.

Believe it or not I use low setting on many things like outside corners.. It causes the weld to just lay flat and blend into the base metal at the toe of the weld.. I like higher setting for plug welds and fillet welds. I haven't seen the need to go up around 400 but I have went lower than 50 and found some pleasing results on certain things.. I think a guy could spend most of his day adjusting on one of these machines and still never feel like he had got everything it had to offer.. The trick is knowing when to say when and just get the job done.. Understanding what each adjustment does to the weld is key to hitting a good place right out of the gate.

We have a Miller Aerowave at work (no longer made). It actually has way too many features on it and because of it, the machine rarely gets used. Everything is independently adjustable on that thing. It has more knobs then any other machine I have ever seen. I think that is the reason Miller discontinued it. It was a high dollar machine and likely very few actually bought them. I know thie doesn;t have anything to do with a dynasty, but I was looking at it the other day at work and it just popped back in my head when reading this... :-)

Looks like you can buy one of Marcella's un needed welders if you want....check out the manifold on that thread....

On our 250EX's, We weld aluminum most of the time at 40 hertz and a lot of electrode negative, maxed out most of the time and the pulser at 500pps. Tungsten sharp then we grind a flat on the end about .050 in diameter. With a flat, square off tip each drop of filler rod is round and not egg shaped, also leaves much flatter welds for me.

What is the benefit of using 500pps pulse all of the time?

[GUNNER]

Buying a machine Marcella has used would be worth every penny if somehow his talent came with the machine!! He's a GOD in this trade !

[Cippee]

High pulse rates focus the arc. Really 500 hp motorcycle that is nuts!! I have a 500 hp car and can't imagine if I had that power with 3000 less pounds.

The fast pulse keeps the arc from wandering on low frequency's. The lower frequency's give a softer arc and the pulse just keeps it focused without making it harsh like the higher frequency's will, also average temperature of the arc will be reduced, so heat saturation will be less with pulse. The round aluminum parts I weld start with 130 amps and by the time I get all the way around them I am at 50 amps to keep the same bead width where they meet. That's without pulse and with pulse I start at 130 and end at 90 amps to have the same bead width.

What material thickness are you using those setting on? I have found that I like the lower Hrtz setting better myself but most people today on these inverters go the other way. I figured that I was just so old school that I was resisting the change. I also prefer the old sine wave over the other 3 I have at my disposal and I know that's also insane sounding but it's just a lot smoother running to me.. Thanks for sharing that information that's the kind of stuff that actually helps people instead of bitching and crying about piggy backing a damn lamp cord and the warranty BS that becomes a waste of everyone's time..

I'm out to the shop now to use those settings and see what I think..

[srp]

I weld billet end caps to .065 aluminum round tubing and then 1/4 plate mounting tabs to the .065 round tubing. I have found a softer weld similar to like a sine wave machine looks best, but with the inverter I can get that look without the cup glowing and burning off the end of the tungsten.

I tried those setting and they do produce a nice job. I also switched up on the wave form while trying that and discovered the Tri wave really looked sweet set like that... The Dynasty just give a few more tools in the belt to borrow one of Jody's lines from tips and tricks.. Every extra tool helps a guy find something that works best...

That's because the part heats up?

I don't think you can have too many tools.

As aluminum gets hotter and hotter, the weld bead just keeps getting wider unless you back up off of the pedal. And then sometimes its better to just let it cool down some before continuing.

I hate welding small parts for this exact reason. When small pieces need an outside corner weld and an inside fillet weld. If you do both right after each other the one you do second always is so hot you loose the ripples. It looks like one solid weld. I was welding these little stops and it took forever for these things to cool off.
