Question re: operation of pulse mode on PowerTig 200DX

[Tantalum711]

Thanks for the response. I've been to weldingtipsandtricks.com many many times now (I wouldn't have an Everlast now if I hadn't) and have probably viewed most of the videos--the TIG related ones quite a few times and learned an incredible amount from them. What you say about the pulser not functioning at low amperage makes sense. I'm not sure how familar you are with the differences in the controls of the 200DX versus the 250EX, but I suspect that it would take some experimenting to get the same results on the 200DX that you could more easily dial in on the 250EX. There's a pot on the foot pedal of the 200DX to control the max current--the knob next to the LED display doesn't do anything with the foot pedal plugged in and the pulser off (it just teases you). I've found it difficult to dial in the exact current range I want on the pedal. It's supposed to be that 0-10 on the pot corresponds to 0-200A on the welder, but it seems like anything under about 7 (supposedly 140A) even when hammered to the floor can't punch a hole in .06 wall SS tubing, whereas anything over about 8.5 is enough to melt that same tubing like a stick of 1/16" filler rod. It may be a while before I start my razor blade welding side business with this model.

We just had a very long discussion about the pulse operation on this welder on the forum, just a few days and several times before.

But to sum it up:
The pulse amp knob is controlling the high stage of the pulse cycle. The knob on the foot pedal, controls the main amp level with pulse on or off, doesn't matter. For use with pulse the foot pedal controls ONLY the low end amps. The pulse amps are set on the panel. That means you are only adjusting one amp value when you press the pedal. The closer you press the pedal to the amp level, the less pulse action is observed. IF your max amp setting is above the pulse amp level, the pulse will effectively shut off. This is for 200DX only. I am not sure which manual you read, but the foot pedal doesn't act as an on/off switch only. Can you tell me where you think it is stating it? I'd like to review it.

I appreciate your reply. I just saw the 3 page exchange regarding this issue today and felt like an idiot for posting. Somehow that exchange didn't come up when I did a search the first time. It's hard enough making sure customers have correct information without people like me trying to confuse the issue with poorly researched posts.
My understanding of how the pulser worked was wrong. It was probably just an assumption on my part that the pedal functioned as an on/off switch with the pulser turned on. I doubt now that it was stated or implied by the manual. I was confused by the results I was getting using the foot pedal in conjuction with the pulser and just assumed that all the control for the pulser was fixed on the main panel with no real input from the pedal itself.
Once again, I am continually impressed by how dedicated the support staff is in making sure customers get the most out of the welders they've purchased. It can't be easy having to answer the same questions over and over again to people of various levels of experience. Thanks, Mark.

Don't beat yourself up too much, repeat threads are just the nature of forums. Otherwise this would just be a list of FAQs. --Ian

don't feel bad, I watched all the tig welding inverter settings videos several times. I finally took some notes, because I could not remember them. When I wrote them down I figured out I had the AC balance set opposite of what it should have been.
