All About: Independent Amplitude and advanced waveform controls

[7A749]

No worries Allan. You're one of the last guys I view as a pot stirrer.

I just wanted to make sure everyone understood the purpose of the thread. I know once things start to unravel, it can get out of control pretty fast.

[C. Livingstone]

Yeah,

Photos would be good. But a video demo would really be great. You know, maybe just some bead-on-plate with a typical wave form and settings, and then showing the amplitude control being changed, and then some more bead-on-plate, with no other changes. Then a little commentary...

I mean, as of right now, I've only noticed one video on YouTube that touches on the amplitude control topic with only the briefest demo and commentary. And if I recall, it mentions increased travel speed as a benefit, maybe also smaller tungsten size.

Have you guys seen it? It's got a guy named Chris Razor in it.

It seems to be about all there is out there as a visual demonstration of amplitude control, but without any actual parameters, theory, or machine adjustment comparison effects included.

Don't have wave or wave amp control,but much interested in how/ why results.
Oscar your techno gets me to reread your posts and clears up some of my dope slaps

First we had triangle wave welders with Mag-amp control.
Then came the SCR square wave. with advanced wave form we now can pick a basic wave form and then Change frequency and the zero point and balance.
All in attempt to give us the best puddle control they can think up.

I needed this post real bad.Since I started to figure out what my Inverter would do, I have been quite overwhelmed with understanding how I can have a En % of say 70 and an Ep % at 50,which is more than 100%.without coming across as completely stupid, I don't ask the questions,I have many.

I am struggling with the percentages of the En and Ep and how they relate to the balance setting,like having a balance of 60% but En at 70%, and Ep at 50%?

[zank]

Are you using an Invertig 221? If yes, the percentages are based on what you set for max amps. So for easy numbers, if you have your machine ser at 100 amps, en for 70%, and ep for 50%, and then you floor the pedal, you would be at 70 amps en and 50 amps ep. It's not additive.

[zank]

As a follow up, I would make it easy on yourself and leave one setting at 100% and then adjust the other to a lower percentage. I think that is more intuitive. For instance, you may want to try to lower your ep to reduce the heat into your tungsten. Leave the EN at 100% and lower your EP to 80%.

[Insaneride]

How do you figure? If your wave looks like this, it's spending more "time" on one side vs the other side

I dont do much aluminum and dont have fancy waveform adjustments but this is just wrong. The horizontal part of wave is time and it looks to be the same time for the positive part of wave as the negative. I just had to clear that up.

I do have balance control and usually keep it on the side that saves tungsten and turn it up only if the aluminum is really dirty.

Don't worry, I cleared that misconception up in a previous post.

You're lucky I'm on Spring Break vacation. I'll see if I can whip up some crude MS Paint drawings in a bit.

The main thing to realize is (with regards to setting the parameters on the machine):

• Balance control is in the time domain only
• Both Main Welding - and Indep-Amplitude control are in the amperage/current domain only

I understand what you all are talking about, but pictures and setting will tell me a lot more. Or do I just have to play with it and see for my self what it does?

That's like asking: can't I just take an online welding course to learn how to weld, or do I have to actually try to weld to learn how to weld?

[mechanic416]

Ok, I see. Bye.

nmaineron,

hopefully these crude diagrams will help your understanding of some of this stuff.













Of course it is not realistic to depict each an every single possible combination of AC balance together with independent amplitude changes. With three degrees of freedom, there are a multitude of combinations that are attainable.

And then along comes pulse, and I can't even remember my phone number.
Nice informative diagram "Oscar".

[dave powelson]

Thanks Oscar!
That's an excellent basic presentation.

[irnworker433]

Ok, guess I'll have to clarify what this thread is for

IT IS FOR SHARING FEATURES AND CHARACTERISTICS OF WAVE SHAPE AND AMPLITUDE SETTINGS USED ON ADVANCED INVERTER TIGS!!!!

In example: What an individual user has used, tried or experimented with and its related outcome... Basically a thread where ppl can share and exchange ideas regarding machine setup with others so all can benefit from it..

IT WAS NOT CREATED TO ARGUE THEORY, DEFINITIONS AND OPINIONS. IT SURE AS HELL WAS NOT CREATED TO BECOME A DICK SWINGING CONTEST EITHER.

ANY FURTHER POSTS REVERTING TO SUCH WILL BE REMOVED.

THANKS
