AC Frequency Made Simple: Primeweld TIG 225x Tutorial

New products being added weekly.

To show the affects on AC frequency, I stacked several beads using different frequencies from 40hz to 200hz.
100-120hz is a good all around setting but I like to lower the frequency for thicker metal or when I want a fat bead.

Higher AC frequency settings help focus the arc cone for a pinpointed arc.

Other weld videos are a waste of time! This guy is the real deal! Helped me pass a weld test a few years ago! Thank you for everything you do.

These videos have been spot on recently! My buddy has the same machine and we’re still learning it. I’ve learned a lot from this channel, thanks for the great content!

I have the same machine. And I'm trying to learn and teach myself aluminum welding. This was very helpful and I'm sure I'll be watching many more of your videos. Thank you for the very informative and broken down information.

the other day I welded up a worn through cut in a car air conditioning line and I dialed my 280DX up to 320hz. Worked great

Thank you for providing the best educational videos!

Awesome instruction... I do similar with mig when cladding.

[aurktman]

This is the machine I have, will certainly use this as my how-to!

Saya mulai belajar dengan anda, bagaimana menggunakan mesin las dengan baik serta hasil pengelasannya... terimakasih saudaraku...

Awesome visual explanation of AC Freq. This could also be a good drill for practicing edge welds vs a single pass on the edge of a coupon. It reminds me of your "padding beads" video.

I find this video to be very true based on my personal experience.
my fronius goes up to 2kHz screams like crazy.

Another good, informative video to the point. Thank you

[DeerAssassin]

I agree with many comments, you have explained some settings very well. Where is your video concerning-based current settings? I’ve been searching have been unable to find it.

REALLY APPRECIATE YOUR STRAIGHT FORWARD VIDEOS, YOU ARE REALLY STEADY, KEEP UP THE GOOD WORK.

Can you pulse SMAW with this? Also how do you adjust arc force/ Dig? Thank you!

[cathydoyle]

Could you do a video lesson on welding aluminum pipe, I can go to work for a water pipe company if I can TIG weld al pipe rolled out. I own the Prime weld 225.Thank you

Really enjoy your wideos. Just got primeweld 225 and I am new in tig. I would like to upgrade the cups which came with unit without breaking my wallet. Can you suggest the minimum tip of cups what I should get for aluminum and steinless? Thanks, Milan

[mikerobertson]

Long time viewer and thank you for sharing your obvious wealth of experience of the whole scope of the welding activities. I do however, have a question. Have you ever tried to weld copper?

[alanmony]

This is great info, just what I need. I have this machine and just learning to weld ally. I'm trying to build a custom intake manifold welding .063 6061 round tube to a .375" 6061 thick flange, I'm guessing I'll have to use the pedal to raise and lower the amps. Any advice out there on settings for this project?

[WelderBFamily]

Great info!!! 👨🏾‍🏭💰🤙🏿 Can you do DC next?

I'm having trouble with arc starts on AC with the Primeweld machine. Does anyone know what to adjust the high frequency arc gap to, inside the machine?
