Some of you may not know that Mr. TIG passed in 2022, many thanks for all the help over the years!

Rest in peace to a true legend of the welding world. This man taught millions of people very valuable things. He always had such a great attitude and integrity, I bet his coworkers loved him in the shop. Thanks for everything Mr. Tig, you’ll forever live on in my world and many others.

Scratch start: position the tungsten really close to the work piece without touching then drag your filler rod making contact with the work piece and tungsten this will initiate the arc without leaving any tungsten inclusion in the work piece. Passed plenty of X-Ray pipe welds using this method.

+Haz Mat I couldn't respond directly to your comment for some reason, but the torch we are using is a CK 9F with a superflex cable. You can get one on the Weld.com store here:

Great video and badly needed to explain simply the 3 different start systems - Thank you for taking the time to do this.

[thePrson]

I was taught to run my filler over the tungsten and make the connection there vs trying to scratch the material with the tungsten so as not to leave the top in material

[marioep]

I have learned so much with you and now let's say I'm a good welder and that is helping me a lot in my job, what else can I say, just a big thank you from me and everyone here for sharing us your knowledge. once again thank you Mr tig.

Joe,     Certainly you can use high frequency start and a foot control for walking the cup methods.  One of the reasons we demonstrate scratch starting and no foot control is because of "field" welding.  Most welders in the field have a generator which is capable of stick welding and can tig  but only have scratch start available. High frequency is an expensive add-on so it is easy to see how this technique developed.  good luck Mister tig

[chuckgilbert]

As a beginner I started out trying to scratch start, I watched this video then looked at my machine and see it as lift start and HF start settings, wow I can not wait to get back to my shop and try HF start

[markallen]

Just a suggestion or request.  Maybe include a window inset in the corner of the screen while you are welding so we can see what your foot is doing at the same time you are making a motion with your welder. 

[alexrowdy]

Perfectly explained, thanks ! Now I understand why is this bulky valve on my torch.

[madaxe]

I’m not a welder, but the last year pr so I’ve been working with pressure welders, and they all just use basic “scratchies” in the field. So When I wanted to learn to Tig, I asked them what I should buy, they all said, “but a scratchy, if you can lay good welds with that, you can lay good welds with anything else”... so I did, but I keep ending up with filler rod material on my tungsten, I use the filler rod scratch method the tubies taught me.

[fredwilliam]

My everlast tig welder supports both lift start and hf start. It is nice to know when it is appropriate to use each so thank you for the explanation.

[vstm]

very informative and very simple in the way it was explained. thank you Sir, cheers from Poland

[eugenecosentino]

On scratch start you can also start the arc with a filler rod then do your weld lengthen the arc then snap out of the weld not to leave any fish eyes or tungsten in the weld if it is going to be x-rayed.

[bradthurkle]

Great video thanks. Ya live and learn. Just a welder with the scratch start. I didn’t know there was any difference until the Chappy told in the shop. Are well I’ll make it work.

[renaissanceman]

Thanks for the valuable information Mr. Tig and Rest In Peace. You will be missed. 4-17-22

[ClandestineWoodwork]

The exact video I needed at the exact time. It's been 20+ years since I've Tig welded, and that was apparently an HF starting unit. My current Tig is a lift start. I didn't know that.

[silverssonyoutube]

HF with button start control on the torch handle is the way to go it's more fast and higher accuracy of control. Scratch start is messy contamination of the tungsten happens . Lift start would be better than having scratch.

[xler]

There's also touch HF start, combo of HF and lift arc the Fronius has this feature !!!!
