Your TIG Pulsing Capabilities

admin

for those who have TIG with pulsing, can you tell me how you can adjust freq and duty-cycle of the pulse, and what the freq range is.
Reply:No clue.Because...I..Don't...Need....Pulse....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.

Reply:exactly, looking for your machine make/model and how it pulses. do you have PWM control over the pulsing?? if so, what freq range and duty cycle?

Reply:Pulse with your foot if you want to be proficient as a welder when you need to. I used a pulse setting on a machine once, and it was so easy it was a friggin joke. It really gives people a false positive on being a good welder. Learn to do it manually. Different story if you're a mass production shop hiring cheap labor and needing to pump out a product that calls for it. Other than that.....manual with your foot.I hate being bi-polar it's awsomeMy Heroes Have Always Been Cowboys

Reply:Originally Posted by shovelonWhat is PWM?  Don't know if duty cycle has any bearing on what I do with pulse.

Reply:No flame war guys, just my point. Not every machine has a pulse feature, so its good to be well rounded and ready. Alot of guys these days just shoot for easy quality and then get tripped up at crunch time.I hate being bi-polar it's awsomeMy Heroes Have Always Been Cowboys

Reply:Originally Posted by Mikel_24I don't even TIG but as far as I know, PWM stands for Pulse Width Modulation (Telecomms background). The wider the pulse, the higher the heat input (that's what I have been told).To the OP, search for Jody (WeldingTipsAndTricks) videos regarding pulse settings... As I said, I don't even TIG but I watch them anyway and I think he does a great job explaining the fundamentals as well as some specific settings for certain materials and situations.Mikel

Reply:My current machine does not have pulse. I was able to spend some time on a dynasty a few weeks back and came away really impressed. I was welding some thin steel tubing (0.024" - 0.032" wall) at 200-250 PPS (40% peak time and 25% background current) and was really excited about the control. I weld the same material every day with my machine and no pulse, so it's not as if it allowed me to do something I couldn't do before. But I did notice a significant difference in how tight the arc was and I could move faster because nothing got squirrelly. Hey, I'm just one data point. I'm saving for a dynasty. I really want to try some thin titanium at high pulse rates to see if it narrows up the area above 600F. It would be fun to see the results with say a #8 cup and small gas lens.

Reply:The Pulse and sequencer boards were extra on my Syncrowave  250I love both options...  either one has their place...Sequencer comes in handy with a momentary switch...and the pulse has many applications... Stainless Steel is probably where I "NEED" it...Other places are a luxury option...If you ain't used it...  you don't know what your missing...By the way....  200 pulse per sec ????  WTF   what's the use ?I like the tennis shoe and coffee comments  HAAAAAAAAA !.Gotta Fly....

Reply:I'm using pulse when welding 12mm (1/2 inch) titanium to prevent overheating it. 200/80 (hi/lo current), 2,5 pps, 50/50 time. It realy helps with discoloration, all of my welds are silver with #6 cup used, I dab the filler at every pulse.Using it for 0,6-1mm stainless - 100pps, 150/70 hi/lo, 50/50 time. It focuses the arc and simply make it easier to weld. And also using it for welding gaps in steel or SS with 35pps and 60 on time. That prevents keyholing.We have OTC 300amp tig, which have memory function, so I saved my settings for different stuff that I weld and it takes me 5sec to recal these settings. You can do it all without the pulse but some things are easier to with it.

Reply:Depends on the machine if you can adjust the pulse duty or some call it the pulse width.Torchmate 2x2 CNC with Flashcut CNC controlsHypertherm Powermax45 Esab ET220i Razorweld 195 MigRazorweld 200ac/dc TigTormach 770, Tormach xstechRazorweld, Vipercut/Vipermig, SSC Foot Pedal Dealer
Reply:It's usually called Peak Time (as a percentage of the period duration). And then there's background current (as a percentage of welding current called for by the pedal or panel knob). The 3rd setting is of course frequency.Welding/Fab Pics: www.UtahWeld.com
