everlast "advanced tig pulse" anyone actually use it?

admin

Ok,  there are a lot of positive descriptions of Everlasts "advanced tig pulse" where the positive half of the pulse is AC and the negative half is DC.  I'd like to get some observations from someone that has actually used it.  This is of interest to me because the Everlast machines WITHOUT "advanced tig pulse" have AC frequency adjust as well as AC balance and also "regular" pulse and regular square wave and are $800 cheaper.   I weld 2mm aluminum, is the extra price worth it?J.P.s. I have been using a diversion 180, need a second machine as two of us work together.
Reply:The advanced pulse offers greater penetration on heavy metal, and better bead profile and quick freezing on thinner metals.  Wave form control is one of the highlights of this machine which also improves the arc characteristics for each job, in particular the triangular wave form helps on thinner metal.There is no comparison between the machine you have and the capabilities of this unit. I've used the 210 and the 255.  Both units perform excellently.  I work for the company yes.  But I try to give advice based off what I've experienced and used personally, and the wave form is as important as the advanced pulse.  Having digital control also improves the unit overall.Esab Migmaster 250Lincoln SA 200Lincoln Ranger 8Smith Oxy Fuel setupEverlast PowerPlasma 80Everlast Power iMIG 160Everlast Power iMIG 205 Everlast Power iMIG 140EEverlast PowerARC 300Everlast PowerARC 140STEverlast PowerTIG 255EXT

Reply:Originally Posted by soutthpawDon't suppose you have a graph that shows exactly what the waveform is doing in this "advanced AC " pulse.   Is it like a split amplitude to put more current on one side of the sine way than the other?
Reply:I don't have a chart to show you right now that I can get my hands on.  The biggest thing is that most people don't understand basic pulse to begin with and think it is just modifying the AC amplitude, and it's not.  We have a couple of videos up showing it in use, in fact one of the latest ones posted to the youtube channel.  In the advanced pulse, you have two specific parts of the pulse cycle.  The first is the "Peak" amperage stage which is the highest point of amperage that the pulse achieves.  On the Advanced pulse that is assigned to the AC part of the pulse.  The other part of the pulse is the base or "back ground" part of the pulse, which is the lowest amperage the pulse achieves.  This stage is assigned to DC.  The pulse is simply cycling between AC and DC operation.   Along with the information already posted, I think that is about as good as it can be explained .  Esab Migmaster 250Lincoln SA 200Lincoln Ranger 8Smith Oxy Fuel setupEverlast PowerPlasma 80Everlast Power iMIG 160Everlast Power iMIG 205 Everlast Power iMIG 140EEverlast PowerARC 300Everlast PowerARC 140STEverlast PowerTIG 255EXT
Reply:I watched the video and read the description.It seems the advanced pulse is like Kemppi's Mix tig in which the current alternates between AC and DC.In Kemppi's mix tig (don't know about the Everlast) you can set independently all the parameters, so apart from the usual settings for AC (balance, frequency & waveform) you set the percentage of the time the unit works in AC and the cycle time of the DC pulse.Aluminum oxide takes a few seconds to form and in that time the machine switches to DC increasing penetration and minimizing the heat that goes onto the tungsten, before the oxide forms it switches back to AC and the cycle starts again.It is a very convenient feature that allows you to use it for many different applications such as welding different thicknesses, increasing penetration in thick pieces etc.
Reply:Yes. Taz.  That sums it up.  But it also works nicely on thin gauge materials creating a fast freeze nicely contoured bead if adjusted for it.Esab Migmaster 250Lincoln SA 200Lincoln Ranger 8Smith Oxy Fuel setupEverlast PowerPlasma 80Everlast Power iMIG 160Everlast Power iMIG 205 Everlast Power iMIG 140EEverlast PowerARC 300Everlast PowerARC 140STEverlast PowerTIG 255EXT
Reply:Wow,  thanks for the feedback! I just ordered the 210ext from Everlast. I'm sure it will be a step up. It seems like it has the features of a $6000 miller dynasty at less than a third of the price.  Everlast actually created the sales opportunity because I would have purchased nothing rather than pay $6000k for (more) miller equipment, and I probably would not have bought cheaper Chinese equipment as I've had some bad luck with that in the past.  The 5 year warranty was what convinced me it was worth a try. If this machine does well I see more Everlast equipment ahead. The only concern I still have about it is fan noise as it doesn't have a fan-on-demand feature.  I'm probably going to operate the machine on thin aluminum 95% of the time around 125 amps  which should be easy for this machine and not require 100% fan speed.  But I think the machine fan runs at full speed all the time anyway. Not sure.  Anyway, I'm excited to get it.Joe
Reply:Would this advanced AC work well for welding through Anodized aluminum.    In another thread, bump welding Anodized was discussed wether high current pulses with the pedal would burn through the anodizing.   Assuming this pulse feature would let you run a much higher than normal current for the thickness of the aluminium being welded it seems it would lend itself to such an application.    Anyone have one that wants to give this a try? Probably with the lowest Hz setting, 1hz? Maybe.Tiger Sales:  AHP Distributor    www.tigersalesco.comAHP200x; AHP 160ST; MM350P,  Spoolmatic 30A; Everlast PowerTig 185; Thermal Dynamics 60i plasma.  For Sale:  Cobra Mig 250 w/ Push-pull gun.  Lincoln Wirematic 250
Reply:I believe Jody had a video about advanced tig welding control, might try and look it up. Ill look for a link in the meantime, saw it surfing youtube on my xbox last night.
