Re: Help me understand AC Waveform? Adjusting EN & EP independantly on a Dynasty 700

There is a good sticky post about this, which I hope this one gets merged to to keep all the info in a concise way.

The sticky addresses your question about how independent amplitude affects balance, which the short answer is: it doesn't.

The waveform selections control the shape and ramp rates of the arc current. A good base point is to not adjust it and leave it equal amplitude until you learn what adjusting it does. It is not necessary to adjust them.

The manual for the 700 has pretty good explanations for the waveform types.

The HTP invertig will do that too. Ya gotta scratch your balls in a counterclockwise motion to get into the menu. Jeff told me, don't screw with it for now. lol

Miller's forum also has a (very large) sticky on Dynasty setup, well worth reading.

 

Re: Help me understand AC Waveform? Adjusting EN & EP independantly on a Dynasty 700

I had an everlast welder that I have been using for a few years now and got a deal on a Miller Dynasty 700. The machine is complete overkill for me, but I got a good deal on it so I couldn't pass it up.

The question I have is regarding the AC waveform adjustments.

On my everlast I could adjust ac balance and ac frequency, but on the miller I now have an option for En & Ep independently.

So I guess my question is where is a good "base point" to start so I can start making adjustments from there?

Also how do they affect each other? If I have ac balance set at 60 how do the En & Ep affect that?

Also what are the differences between:

Advanced Squarewave
Soft Squarewave
Sine wave
Triangular wave

Thanks!

The way I see it is that at 60% balance EN, you are left with 40% EP duration. With that you could go equal or even an EP that is lower than the EN.

If you up the balance to say 80% EN duration, then you are left with 20% EP duration and have less cleaning. You could counteract that with increasing the EP amperage to say 150% or the EN to get a stronger(yet less duration) burst of cleaning.

So less EP duration in the balance setting will require more EP amperage to achieve a similar cleaning. The advantage that Zank found was the tungsten benefited by having less time to overheat and melt the tungsten regardless of amperage.

Took me a while to reason that out.
