- From www.kevincaron.com - Artist Kevin Caron explains TIG welding lift start, high frequency start, and even scratch start ....
A new TIG welder asked, "What is the difference between high frequency and lift start?"
High frequency start is what most TIG welders use except when they are welding on a car, around computers or electronics. Then you want to use lift start. Around a car, for instance, if you want to fix a hole in the exhaust pipe by welding a patch on it, high frequency start can affect the computers vehicles have today. Around electronics or computers, you also should only use lift start, as high frequency start can affect them.
With high frequency start, you can just get close to your metal - 1/8" to 1/4" - click your trigger or step on your foot pedal, and the high frequency start in the machine will jump from the tungsten to the metal to start your arc so you can weld. Once your arc is started, the high frequency function is turned off until you are ready to start the arc again.
With lift start, you still use your trigger or foot pedal, but you don't have an arc jump between the tip of the tungsten and the metal. Instead, you put your cup down on the metal, click your trigger or push down on your foot pedal. You then roll your torch upright so that the tungsten touches the metal as you lift up the torch in a smooth little move.
Caron is showing this rolling away, but when he is welding, he rolls it toward himself.
Machines can offer high frequency or lift start or both, like the welder he is using, the Everlast PowerTIG 255EXT. "This one is actually kind of special," Caron explains. It has an electronic high frequency component, so there are no points. On most cheaper TIG welders with high frequency, you have to occasionally adjust those points.
There is a cost difference. A machine with high frequency is going to cost a little more than one that just has lift start.
And then there are even cheaper TIG welders that use scratch start. With TIG scratch start, the minute you turn on the machine, the tungsten is hot electrically. So you literally tap or scratch the tungsten to start it, like an arc welder (stick welder) or a match to get the arc started. To break the arc, you simply pull the torch away from the metal.
So which one should you get? If Caron were going to buy a new machine, he'd look for a TIG welder with both high frequency and lift start. Preferably, like this TIG welder, he'd choose one with electronic high frequency so there are no points to adjust or wear out.

This guy has a straightforward simple way of explaining things i really like.
I'm small farmer by, no means expert. I build what I cant afford, hay grapples, welding tables, turned a disk chisel into a ripper. Thanks for your videos. Both entertaining and informational and have helped me become more proficient.
Right on! Thank you for watching and posting.
Great point you made about the difference in the HF vs LIFT, the HF can seriously damage the vehicle electronics, that helped immensely, Thank You!
Thank you for watching and posting.
No matter how smart I think I am, I’m not really that smart. I’ve just started welding after a 13 year lapse. Never used DC TIG before, and lift start has beaten me too many times, with me welding the tip to the metal. At least it forced me to design and build a good, fast tungsten grinder. LOL! Now, I know what I was doing wrong, thanks to this short video Kevin. It’s really appreciated. In fact, all of your videos are interesting and useful. I wish I could afford your work, and have somewhere to put it.
Don't forget to look at my 3d printed work. You can see it on my website.

Thank you for watching, been a fun ride getting to here and just wanted to share.
It’s great stuff.
with the growing popularity of TIG, this is valuable information for many people. thanks guys!
I've got lift start on my everlast welder. I've never used that feature but now I'm going to give it a try.
It has it uses but I don't use it that often.
Thanks for watching.
I am glad you told me about the HF on a car or truck, I am wanting a good tig for my gagrage and had been reading about the scratch start n lift tig. I always read before I buy anything n was looking into a 3 in 1 machine. With Tig, stick , and mig. But I have only found ones with the lift tig or Hf start. I didn't know they was that much difference in Tig with low pulse,high pulse, Hf start and so forth. Thanks for doin this video cause I hadn't read any where not to use HF on a car..
Thanks for watching and posting Dale! Great to have you in the club.
Oh man, thank the welding gods for CZcams, learning so much, thanks mate.
WOW ...five minutes of talking and actually NOT explain "lift start" properly. EVERYONE ...look at the other explanations of "lift start" on CZcams. The best one I found stated and showed ... put the tungsten on the material where you are going to start welding, and as soon as you lift (break contact with the material), the arc is initiated. STOP WITH ALL THE OTHER MUMBO JUMBO WORDS!!!!! Go to czcams.com/video/7Tv4H2RNssE/video.html and then to 3:15 for a very simple explanation that ends at 3:45 ....so this takes 30 SECONDS. Of course there is the different demos and OTHER discussions that contribute to understanding what's going on ....but I could not find this simple explanation in any "other" CZcams "tutorial". Don't forget, these "tutorials" are done by people with and without knowledge and experience. They are driven by their own personalities and/or quest to make some money, either on their own or by promoting equipment. ------- Learn to identify the people who are capable of providing good solid information ...as opposed to a "SHAM-WOW" entertainer.
Of all the videos on this subject Kevin does the best job. The other guys are all hot shots. Look at me is all they brag about. Keep up the good work Kevin. Snd thsnk you.
Wow, thank you! Always nice to hear for the guys on the other end of the internet. Thank you for watching and posting.
I spied your Pine Bluff anvil. Jim Linzy was well thought of in the Farrier trade, may he RIP.
It is a great anvil! Was very lucky to get this one.
Kevin Caron, Artist. I just ordered my first Everlast. Learning a lot from your videos. Good stuff!
Thanks for watching!
For some reason your sound is only recording mono and most of your videos I have to go behind unplug my speaker and find the other wiring plug it in because I only have one currently so just a heads up
Sounds like it's on your end.
But thanks for the heads up.
Will give it a listen.
With HF start can the cup touch the material you’re about to weld?
Yes, just don't touch the tungsten to the metal.
@@KevincaronSculpture ok, thank you 🙏🏼
Is it possible to have a torch switch with a lift start machine with no foot pedal capability such as my Everlast power arc 200 ST?
Sure ,just have to wire it up.
Thanks for the explanation, Kevin!
If anyone is looking for Kevin's FB page the one in description is no longer. This is current one as of date of this posting facebook.com/kevincaronart
Thanks for keeping track of me Maggie. So many things to keep in mind now days!
@@KevincaronSculpture Cheers!
Great info Kevin.
2 questions. When I try 2 lift start, using a pedal, the tungsten sticks 2 the base metal when I lift up. Any thoughts on why? Also, when using HF I notice my lights dim slightly when I push the pedal. Any thoughts on a cause?
Probably just a heavy hand on your part. Would love to watch you to get a better sense of what you are doing. As to the lights dimming, you are on too small of a circuit for power. If you can switch to a 30 amp line you would be better.
Thank u.
Thanks for the useful information again. Not sure if I am the only one but I only hear audio from the left channel and the audio sounds low.
Ed Chin Yes, I experienced the same thing. I was hoping it was a record edit issue and not on my end.
Ed Chin I think I tend to sound like that by days end!! Sorry, think the mic was not plugged in all the way... My fault.
Kevin Caron, Artist No worries. Still excellent information. Thanks!
A question here from a non TIG weldor. I thought dipping the tungsten in the puddle was a no-no in TIG, how do you avoid this with lift or scratch start?
dahveed284 Low starting amps for this type of start.
Supposed to keep the tungsten from getting contaminated.
Always comes down to practice,

Does using scratch or lift start require you to grind the tungsten more often, due to contamination? Or is that more from dipping in the puddle, and less an issue when starting weld? Or possibly "yes, more often, but not unreasonably so"?
mlindholm Yes, especially with scratch start where you have to "break off" your arc you also put arc strikes across your job.

I will call you when I get back from archery elk hunting in a week.
That's why you GROUND your machine to earth.. Disconnect the batts before you weld on any car or truck. No matter of the year. Short out welding will fry any motor.
sdjb111 well, I’ll tell you something. You really have to be careful with the word “ground”, as it isn’t what you think it is in welding. Every type of electrical and electronics uses the theory of current going from negative to positive. But welding uses the theory of current moving from positive to negative.
What that means is that the supposed “ground” clamp isn’t really the ground you think it is. If you have a piece of equipment that is grounded, and turn it off without disconnecting it from the power source, when you weld, you’ll get a circuit formed. With a mig welder, for example, the mig wire will complete the circuit even when you’re not welding, if you push the button, and the mig wire will act as a heater, and could melt, and damage the machine.
we call that scratch start ,So he's a question to explain to you veuves we use oxford bantam ac oil welders in Blity , & use a t ac /dc buzretifier 15 quid to convert the for Tig welding , so check that out i suppose you will not have a Oil cooled welder so you will have to use a Sander Air cooled welder most uninitiated tend to use , do them a favor & exspan how they can cover there ac welder to a tig . kit to weld that car sill on . LOL go for it son . .
Have to look into that. Thanks for watching and posting .
looked like it was HOT while filming!
Something happened with the audio on this video - its REALLY bad.
