Dynasty Processes-Set Up

[ASKANDY]

It has been requested by a few people to have a dedicated INVERTER thread and stick it.
This will be a thread mainly for Dynasty machines with their multi set up features. Diversions, while Inverters, are pretty basic and don't really belong in this group.
This thread is for specific questions regarding set up, menu features, processes or general experiences that feature the Dynasty type machines.

There also have been a lot of requests for a Dynasty book. Even though this is a GREAT idea and has been looked at, our resources at this time are too thin to take on this exhausting task. It's not as easy as jotting down notes on how the Dynasty welds. It has to follow a progression of features and benefits along with weld samples and practical applications examples.
If and when the economy picks back up and we gain some additional weld engineers, an in depth book on Dynasty functions could be possible.

Until then, this thread should help gather some data to help our advanced inverter users and be a collective area where our weld engineers can browse, time willing, and participate.

This is NOT an area for service issues. I'd like to keep this welding related.

Thanks!
Andy

A super idea; I for one will be looking forward to seeing it. Many thanks

I will watch this thread on a regular basis too.

Hey all,

Like Andy said, we have realized a desire for an advanced TIG welding setup guide for our more complex products like the Dynasty, but unfortunatly his comments about available resources is accurate. I did want to start building this thread with member submitted parameters.

Here is a link to another thread which explains ballance, independant amplitude adjustments and frequency for welding thick aluminum (1/2 and up) with a Dynasty 350.

I hope this helps.

Here's the link to the AC TIG: balance control vs. differential current adjustment thread.

Joe, your post does not connect to a site.

Thanks for the good anwers! I have been trying the "soft" square wave, and the following settings

300 amps EN
150 amps EP
80% balance
(the frequency has varied, depending on the joint configuration).

Oh, by the way, I am mostly welding on 1/2" aluminum. (Sometimes it is as thick as 1" though.)

These parameters have been working pretty well. Thanks again!

Just finished an aluminum sign support for a restaurant.

It is a V shape with 2 pieces of 3/*" thick alum plate welded to a 6" x 6" x 1/2" square alum tube.

Settings for my Dynasty 350 are as follows:

AC frequency - 200 Hz

Waveform - Advanced square wave

Amperage 275
EN - whatever the Dynasty calculated - sorry I didn't think to check until I was done. I can recheck the values.
EP - whatever the Dynasty calculated

Balance - 70%

Tungsten - 1/8" pointed 2% thorium - all I have in 1/8"

Tig wire - 3/32" 4043 alloy.

The job went well even though my beads are sloppy.

I did make sure to clean and clean the metals and this saved me from lots of cussing.

One effect I noticed was that the arc seemed to be very "forceful" for want of a better term. By this I mean that there was a dimple in the center of my arc puddle and the alum seemed to be repelled from the tungsten at the tip.

I got a 1/2" thick piece of scrap and just ran a bead with no filler and had the same effect. I even tried pushing the tungsten into the puddle to see if I could get the tungsten to touch the alum but the puddle just parted like Moses and the water.
Have never seen this effect before but again I haven't done a lot of alum.
Also tried same settings at 100 and 60 Hz with similar results.

So is this normal or am I doing something wrong.?

I have noticed this too on high current settings, I dont have a clue why it does it either, but I dont do much aluminum welding either. I dont seem to have the problem with thinner material.

You are absolutely right. I recieved a very speedy reply from Miller about this, and they said the same thing.
Don't you hate it when stuff becomes obsolete so quick? I was thinking of selling the Dynasty as i have a new (to me) Syncrowave 250, but i might as well keep it, as i won't get much for the "old style".

Are their ways to improve the starts on an old 200DX?
