ive been a welder at the same shop for 35 years. i just discovered all the videos online. Some are very informative, some not so much. One thing that im impressed with is the evolution of the power supplies. Ive been using transformer supplies from the 50s.I wish I had a machine that i could adjust like the one he's using here. i was unaware of all of the waves available on the new machines. Pretty cool.
@@mitchstephen5491 OK so this explains why the amount of heat transfert is so much weaker. This should be half for sine as compared to square and even less for triangle...
I am using a brand new Everlast Power Tig 325 EXT and the Advanced Square wave works with your settings but the but the Soft Square Wave acts just like i turned on the pulse (the pulse is off) and can't establish a puddle. I am a welder by trade although my tig experience is with a Miller Dailarc 250 i expect a learning curve because i have been doing stick and fluxcore welding in steel construction for the last 20-years.
I love my Everlast welders, but didn't know you guys had a youtube channel. Awesome content with great quality shots and information. Thank you for taking the time to make these.
Glad to finally understand the triangle and square waves. As I'm not dealing with thin aluminum, a powerpro gives me all I need (actually a little too much) for a thousand less than the EXT
I really appreciate the dual, simultaneous shots of the arc & your torch, filler rod, & viewing angles as you go. As a newbie still figuring out the mechanics of keeping both torch and filler rod stable, I noted your feed hand wrist prop'd on the table - with just enough hand motion to feed rod. Definitely gonna try it this way as looks like good way to improve consistency.
Being stable, and comfortable are about half the battle. Its not always possible to have a hand prop, but it certainly helps when you can. It takes a bit to figure out how much pressure you can apply on your arms and still slide them for longer runs
The triangle waveform has a lower heat input as the RMS value is 0.577 times the peak voltage. For comparison the RMS voltage of a sin wave is 0.707 peak voltage and for the square wave it is the same as the peak voltage. As a result the heat input per half wave is the RMS voltage times the amperage divided by the time (of the half wave in seconds). This is why square wave welders can weld thicker material than the old transformer types, or at least one of the reasons. Great presentation.
Nice explanation of all 4, Jesse. Having been weened on Pure W and a transformer, it's a good one to have for the cast and outside corners. A run home to mama setting for the codge crew.
To me, and this is my personal experience, I think sine wave or soft wave would be the best to start out on. They are a lot more forgiving and provide a wider arc. With triangle wave, you have to be very very precise with your arc length or the arc will cut in and out due to the short time at the peaks of EN/EP. Sine wave, with its longer "roll" into each peak is much more forgiving.
Informative video, however it does not let the user know that using Soft Sq., Triangle or Sine Wave you have to turn your amps up by 50 amps to get the amperage that you may need. Another words when the machine is set at Advanced Square Wave what ever you have the amps set at that is what the machine will put out if push the pedal all the way down. Say 100 amps. If you change to a different wave form you will lose about 50 amps of output. This information was given to me by one of the techs in tech support from Everlast on July 2, 2024
With reduced heat input into the base material, you also have less heat going into the tungsten... So at a higher hz(meaning above the transformer standard of 60hz) sine is really easy on the tungsten as well. Advanced square is actually really hard on the tip due to the sudden and radical shift in polarity which will cause more deformation.
Low frequency pulse settings can reduce your overall heat input into the base metal, much like manually pulsing your pedal, by backing off the amperage for the set time frame in-between pulses. Triangle is kind of doing the same thing in a different way without pulsing. You could combine both, but low frequency pulsing is very annoying on your eyes, mine anyway. Remember higher frequency pulsing, 25-30 pps and up, are going to narrow and focus your arc to a smaller area.... same heat input just to a narrower bead. Great for stable focused arc into filled welds, and it's awesome for outside edge welds or welds close to and edge you don't want to encroach upon or notch into.
2 things are missing from this review. 1) depth of penetration for same machine settings. 2) electrode erosion (balling and wandering and starting) for same machine settings. Then cut and etch. Thanks
i have a question about PowerTIG 255ext it comes with a 5 year warranty is that included free shipping both ways if i need warranty repair ? great video !!
It does not include return shipping. However, more often than not, we can diagnose the problem remotely. If it's a board we can send you the board and walk you through the repair to save time.
@@everlastgenerator So the 5 year warranty is a parts warranty only . what if you a person that is not technical with electronics and they open the unit up and get hurt or burn the equipment .So what does Everlast give a so call marketing 5 year warranty so people don't look at Big Blue or the Red box and they have service centers where you can take it to have service by a pro .This make my decisions made different choices to go with some one else I don't know
@@johnversluis3084 we will service the equipment as well if you don't feel safe doing so. We just don't cover the shipping. We've found in almost all cases that our customers would rather swap a board with our help than wait significantly longer for shipping both ways and time for labor.
The welders come with a 5 year parts and labor warranty. You do pay shipping both ways. However, this is the same statement that Miller and Lincoln and others put in their warranties, and parallels them very similarly. You can look it up and see. Now, the units come with an additional 30 day satisfaction warranty. During that 30 days, if something should happen, Everlast pays shipping. This is the most critical period of time for welders with electronics. If electronics are going to fail, they usually do so within the first 30 days of owner ship. The warranty covers this initial period of time, and gives you plenty of time to get the unit out, fire it up, and put it to good use. After that, if something happens, the shipping is fully on you. The service center is located in TN and has full service capability, far more than your typical regional repair center from other brands. Technicians are factory trained, and fully equipped with programming and factory test equipment. This is far beyond the ability of most "other brand" repair centers. When you add in the savings you get from the purchase price over a dynasty or similar model, you will find that you can ship many times back and forth and ( though you won't need to) still not reach the purchase price of a similarly equipped dynasty or other model. The option to repair at home is carefully weighed with Everlast service technicians (which are available for free to diagnose over the phone and even affect basic repairs) and considered on a case by case basis. It is not a given that a customer will even be allowed to service the unit themselves. The design of the Everlast equipment though has largely gone to fully modular, plug and play design. If you have a screw driver, voltage meter, and can plug and unplug basic electrical connectors, most(but not all) repairs can be done simply by unplugging and dismounting a board. In cases where customers make their own repairs, full diagnosis and repair instructions with both print and pictures usually are involved.
That wasn't a true sine wave sound. I bet it actually is a modified sine wave. You should do a video wherein you show the waveform on an oscilloscope, instead of a drawing.
Edit: the text for the first weld should say "advanced square" not "soft square". Sorry for the error.
I wish you had some kind of conversion box that would intercept my adv square from my everlast 200 dv and let alternate it

Crazy how much less heat you get with the triangle wave. Nice work guys.
Tell me if I'm wrong but would this be due to the fact that the indicated current in AC mode is the peak current and not the root mean square current?
It’s only at it’s peak current for a very short time each cycle.

Good lesson on the different waves.

Thanks so much for explaining each one in great detail.
Keep the videos coming. I really like my everlast 250 ex power tig. Had it over 2 years now. Been thinking about the everlast MTS 275
You won't be disappointed 😉
Thanks for watching!
Great explanation Jesse, I used your frequency video in class today. Keep up the great work 🤘🔥
Seriously? Dude, that is kick ass. That just made my day!
this is a great explanation for sure.
Great vid was wondering how each waveform worked thanks!
Now you know 👍
Thanks for all of the videos!! What is the material thickness you are welding?
Thank-you Jesse; You are excellent at explaining so even a newbie can understand.
pretty work Jesse !
The man has skill
Nice explanation of all 4, Jesse. Having been weened on Pure W and a transformer, it's a good one to have for the cast and outside corners. A run home to mama setting for the codge crew.
Excelente que lo subtitularon en español.
POR FAVOR, ojalá los demás lo hagan tambien, porque habemos mucha gente en Mexico que vemos sus videos.
Love my 255ext 👊🏻👊🏻🔥
Great explanation as usual! Keep em coming, I'm learning a lot!👍🏻👍🏻
Great explanation. Keep them coming 👍
Good job
Awesome explanation
Did you use a gas lens or just a standard cup
I run gas lens, typically an 8
So if you have never tig welded before would you suggest triangle wave to slow things down and allow some extra time to see what’s going on???
To me, and this is my personal experience, I think sine wave or soft wave would be the best to start out on. They are a lot more forgiving and provide a wider arc. With triangle wave, you have to be very very precise with your arc length or the arc will cut in and out due to the short time at the peaks of EN/EP. Sine wave, with its longer "roll" into each peak is much more forgiving.
Felicitaciones muy buen video, sólo una pregunta cuál sería la configuración de la máquina?? , para tener una buena referencia, gracias por comentar.
That’s a nice weld with that soft square.
What machine is being used in this video?
Gracias exelente explicación exitos
Very useful information for a newbie like myself, Thank you...
great job
good afternoon friend i'm brazilian and i would like a lot if you can translate your videos i thank you because i have a lot to learn your tips
Hola Jesse, ¿qué máquinas estas usando?
Most tig welders don’t have a wave adjust feature. What wave form do they mostly use?
Typically inverter welders without waveform options are going to be advanced square or soft wave
Great video. Thank you
Hey, can you set a positive have-wave with square and negative with sine or triangle on this machine?
My 210ext has a special mode which spends more time on DC for thick aluminum. Love to see that included.
Thanks as always for a great example
The advanced AC pulse is definitely on the list
Hey! We posted an advanced AC pulse video a few weeks ago if youre still interested in what it does and how to set it up!
@@jessemccollum I'm on it thanks! I find it interesting this is a fairly obscure feature, which appears to really help!
Thanks!
Thanks

Good job.
It looked like the sine wave was causing less contamination on the electrode. Is that typical or was there another reason for that?
With reduced heat input into the base material, you also have less heat going into the tungsten... So at a higher hz(meaning above the transformer standard of 60hz) sine is really easy on the tungsten as well. Advanced square is actually really hard on the tip due to the sudden and radical shift in polarity which will cause more deformation.
@@jessemccollum Good explanation, thank you.
The Sine wave looks good. It didn't leave any toe line porosity or poc marks as I call them.
So sine and triangle wave are more suitable for thin materials? Can that also be compensated by AC/Pulse frequency?
Low frequency pulse settings can reduce your overall heat input into the base metal, much like manually pulsing your pedal, by backing off the amperage for the set time frame in-between pulses. Triangle is kind of doing the same thing in a different way without pulsing. You could combine both, but low frequency pulsing is very annoying on your eyes, mine anyway.

Can someone pls show how to mig thin sheet metal ( autobody) on a mts welder..both spot welds ..rosette...and stich welding panels etc...
Awesome
Love it!
Thanks for watching
Good jog
Very good
Informe Spanish traducción PLEASE
Video and audio mishap... your saying advanced square wave but video caption says soft square wave... which are we actually seeing?
Audio is correct for the first run, its advanced square wave
Sorry for the confusion. The text should say advanced square
Being an inverter welder this likely a modified sine wave not a true sine wave for but good info

What is your face book page...?
It's a long way from the days when tig was called heliarc .
