Your videos are incredibly helpful to noobs like me. Instead of just saying "This is better than that" with no rationale, you always say *WHY* "This is better than that *under THESE circumstances* and for job X but not job Y or Z". Rare combination of "Doing it" skills coupled to "Teachin it" skills!

Thank you young man. Have been welding for almost 50 yrs. Started with scratch start and now trying to refine my pedal. Still feel more comfortable with my old machine.

i'm a novice welder. i'm 49 years old and don't want to waste time with traditional classes and i've taught myself so many other skills i figure i can learn this with a little internet help. this video was extremely helpful to allow me to better understand what i want to buy to begin my journey. i will be buying a high frequency welder because the pedal doesn't have to be part of the equation. setting the max amps on the machine would allow me to use the pedal like an on and off switch if i need to in the beginning. it also ensures that i don't forget the gas

Really enjoy your videos, but couldn't actually see your lift arc ,but I got the idea.

@itzcaseykc Жыл бұрын

Nice how the arc didn't hurt your finger, especially when you weren't grounded. I've seen how another welder rerouted the foot pedal controller to a graduating push button near the top of the head which worked out well for him.

Well done on 10,000 🥳🥳🥳. A really easy to follow explanation. I have an ‘old’ Esetti 200 Amp, ac/dc/pulse TRANSFORMER machine ( HF start), that I bought about twenty years ago. I learned to TIG on this machine , and it’s still going strong. Keep up the great vids. 👏👏 Regards, Robert ( Sydney Australia)

On the lift arc demonstration, your hand was blocking the view of the lift arc. Also, some models of multipurpose machines have foot pedals.

Hi, a good post with introduction of the three TIG welding systems 'but' you should have added the added work to re-sharpen the TIG electrode when you stick it to the work or contaminate it. Always an issue with Scratch Start, less of an issue with Lift Start (but still there) and only an issue with High Frequency if you touch the work. So when starting out you are going to spend a lot of time sharpening electrodes, so even with High Frequency start I ended up sharpening three electrodes at a time so that I could just "hot swap" electrodes while at the welding station to save time. bye

🙋 Hi great video. I have the 225 tig , love it, don't know what I'm doing lol Can you do a lot more on the cnc Table, I need help there. Have the same table not up and running, been in the hospital again. Have it 1 yr and still not running. ❤

@stickyfox Жыл бұрын

My Multi Handler's instruction manual says to hold the electrode in contact for 1-2 seconds before lifting. It sounds like it's screaming when I do it. I guess the idea is there's an inductor there that will make a nice big pop when I lift the tungsten, but there's no way a 40-lb welder has a large enough inductor that it needs 1-2 seconds to fully charge up.

What’s the best cheap lift Tig welder to get started with? I want to learn Tig but I don’t want to break the bank to get a decent welder… I would need a 110 welder too. I don’t have access to 220. Thanks for the video, I’ve never even heard of the high frequency Tig… I subscribed to your channel to btw…

@amcustomfab Жыл бұрын

I honestly have only ever used one lift tig before and that's the prime weld MTS 200 but I know there are other ones out there that are more affordable for lift tig specifically

Hi dose the HF start up without gass or dose the gas have something to do with the arc????

@amcustomfab Жыл бұрын

It will start without gas but you will not have good results for a weld

@elvisvwvw Жыл бұрын

isit possible for lift arc to remove the ground and left it on the post flow. just wondering

@amcustomfab Жыл бұрын

I'm sorry I don't understand the question can you rephrase it?

@elvisvwvw Жыл бұрын

@@amcustomfab sorry for my english, if a post flow of argon is a problem(for lift arc, and scratch welding), can you remove a "ground"(positive lead)from a welding table to stop the arc, and continue to have a gas flow to the weld?

@amcustomfab Жыл бұрын

Oh I understand now. I'm honestly not sure I have never tried that most of the time I will break the ark by turning the torch 90° and then tip the cup back towards the weld to allow for post flow

5:34 its hard to appreciate this kind of shot. the only shot that matters to me. i never understand why people don't retake easy shot like this. not a person who pays attention to details i guess. i don't dislike the video since i also learn something from it, but not warrant a like. sorry mate.

Not sure if anyone mentioned it, you can have lift arc and also use a potentiometer [foot pedal/thumb control] which acts just like your High Frequency demonstration... .It may depend on your machine.....I know that when using lift arc, the gas flow starts with arc initiation on my Miller Dynasty welders, so I can not get a gas pre-flow which is very helpful on welding aluminum to avoid any contamination at beginning of arc start... .I have to use High frequency to allow that , or use a gas valve torch and by pass the solenoid in the machine...... that high frequency arc on your finger tip....yoooowwww, that did not sting you......... .I have been bit a few times and it felt like a bee got me..... cheers my friend, Paul 'Paulie Brown' from weld.com keep up the fabulous work......you have lots of great enthusiasm and knowledge to share......

If you pull the ground off you only get the high frequency doesn't bite at all
