Dynasty Processes-Set Up

Can the pulse feature be used on AC tig process, and is it effective? This is on a dynasty200 DX

Pulse on AC is good for getting a nice consistent lap weld, especially on 1/8" and thinner aluminum. Keeps the heat input lower and the arc nice and focused. I usually run 300 pps, 33% background, 33% peak time and 225 HZ. Welds very nicely.

As a newer user to the Dynasty lineup and newer to TIG welding overall I've found the pulse settings extremely helpful with heat control. I use it with new materials that are thin as the guys stated above, pps range from 1 to 30, sometimes up to 50, but I havent found much benefit for me above 50, 33% across the board for the rest with freq from 125-225 depending on how wide or deep I'm wanting to go with it, however when using thicker materials I end up around 50% ontime and 40% background, freq from 95-225 depending, I've done a lot of repair on older Aluminum snowmobile trailers, when you can't clean inside the tube your welding its hard to not end up with porosity as you pound in the heat, it'll leach the junk through from the inside if you get it too hot. Even with the pulse it's a battle on these, a lot of people won't touch them for this reason, but with pulse I've have great success and happy customers. When doing fusion welds I found that between 1-6 PPS with slightly higher than 33% worked best for me and gave me the best look to the welds with filler rod in use I'd be more in the 15-30 pps and the percentages mentioned above.

I love my Dynasty 350, I wouldn't give it up for anything, I just got a push pull for my MM 252 so I'm anxious to give that a try and see how it works, but my dynasty is a beast with AL.

i am looking for a new air torch for a dynasty 200 - i have conflicting info about whether the weldcraft ls1712r is compatible with the dynasty 200.

I can't find any specific info on the weldcraft site so maybe this torch model is discontinued.

Does anyone have any relevant information as to whether this torch will work or not?

Thanks in advance.

i ended up with your problem about this and i went ahead and bought 1st one and couldnt get the plug in to work on my new dynasty so i sent it back for another and had same problem, so i looked it over real good and noticed the grove in the head was offset to much and if i forced it surely would have bent pins si i took and small points file and opened it up a touch , cause all you really need is for pins to match, it works fine now, if i can be of any other let me know , i hope this helps anyone else before buying this torch. I might have just got a bad batch, beenabean

What current does your Dynasty display when using the pulse feature? I generally set the current higher than necessary and use the pedal to adjust it. I don't often look at the panel display . . . it doesn't display long enough . . . but I wanted to set the max current on a project and use a full pedal to make a consistent bead.

Setup:

Dynasty 300 DX
DC
panel - 100 amps
full pedal
frequency - 40 Hz
peak current time - 40%
background current - 40%

Machine displays 64 amps . . . so it displays average current.

40% x 100 amps = 40
60% x 40 amps = 24
total = 64
