TIG Welding Aluminum: AC Balance Control

[@bjzq8]

These videos are all invaluable resources for pros and amateurs alike. I appreciate you producing and posting them.

[@pedrotorres8901]

man nice beed! my dad taught me . he had his own business.we,put up slot of tank farms.all stainless,and carbon.only well "it" 4;5 times .video was clear and concise! thank you!!!

[@MillerWelders]

+Pedro Torres You're very welcome! We're happy to hear that you liked the video.

[@Andy205ro]

Happy new year welders! May your stick rod reach more penetration from all positions

[@premvee2515]

Thanks to Miller team good information for me

[@MillerWelders]

Miller agrees that it would be nice if there was a standard to make things easier as an industry. Since there isn’t, Miller has chosen to use what we have historically used when discussing what results in an arc when adjusting the AC balance: “%” as it relates to balance control, refers to percentage of DCEN (DC-) versus DCEP (DC+) in an AC arc. When it comes to Miller products, this is consistent for all our AC capable TIG machines when the balance setting is adjustable.

The Dynasty 200 DX is the best machine on the market, light weight, welds great, frequency adjustment to focus the bead. I have a trailblazer 300 and can run my Dynasty off of the Trailblazer. It lets me weld anything anywhere.

[@martinandersson5278]

Its not the best machine that size in the market The EWM Tetrix 230 is far more superior and advance

[@nishantkamble7586]

Nice viedo

[@illestk24civic]

The guy in the background killed me

[@dougankrum3328]

+illestk24civic ...yeah, he's looking at the stuff like...'What is this sheet'.......

[@illestk24civic]

+Doug Ankrum right hahahaha

[@prebaned]

This guy is good, but my Lord, I can't be the only one watching this and being frightened to tears..

[@michaelcomeroski1044]

Brent, you brushed right over the EN & EP settings...

[@spelunkerd]

What would an oscilloscope show when ac balance is adjusted? Is it as simple as adjusting the midpoint of the sine wave, created by adding a baseline negative current on top of a simple sine wave?

[@MillerWelders]

Hi, thank you for the question. We recommend giving our service line a call to talk this through with a tech. The number is 920-734-9821. Thanks.

[@Andy205ro]

@nielsmiller The new model Maxstar STH160, is it made for Europe only ??

[@ExpectRust]

Ah, so you're the guy in the video. You presented the info well, sorry about the eyebrow comment, it really is just a bit distracting. Good luck working @ Miller!

[@svedr]

does that mean i dont need to clean aluminium with a stainless wire brush before i start welding, if i have ac balance setting?

[@jj9739]

Also....very informative!

[@bornat420am]

What about the independent en/ep balance control? If balance is set to 75 can that setting be fined tuned even further

[@MillerWelders]

Thank you for reaching out. Please keep in mind that this video was developed to illustrate a weld position and the specific welding techniques/weld settings used are not necessarily best for all applications. The Specification Sheet from the manufacturer of the filler metal you use is the best tool to determine starting welding parameters. Please let us know if you have any further questions. Thank you.

[@thehegt]

What type of of tungsten in the video ? Red or green ? I’m using red tungsten to use on the ac it work but not too long the tip got mess up .

[@MillerWelders]

Thanks for reaching out. For tungsten recommendations for your specific application, please give our team a call at 92--734-9821.

[@bendoherty7721]

First one with shiny puddle he kept his filler wire in the shield. The second one with pepper in the puddle he kept taking the filler out of the shield, letting the oxygen attack the hot metal of the filler and then shoving it back in the puddle. No matter what the settings, if you do that you will all get pepper

[@cherylandmoaka]

Sorry but that last comment kills me... LMAO!!!

[@محمدراشد-ط3ه]

How much the price of the machine

[@MillerWelders]

Thanks for reaching out. You can find prices for our machines here: www.millerwelds.com/equipment

[@dougankrum3328]

So, maybe I need to up-grade from my 1956 P&H '300' AC/DC TIG welder? Perhaps a newer machine to go along with my 1981 MillerMatic 200 MIG....?

[@MillerWelders]

+Doug Ankrum For information on prices and products available in your area, we recommend reaching out to a local distributor near you. You can find your nearest distributor with the following link: www.millerwelds.com/where-to-buy?buy=1. Let us know if you have any questions.

[@andreasshammas9812]

IF WE SAY 70% balance that means that the electrode is joint with negative pole 7times and 3 times with positive?

[@MillerWelders]

The balance is measuring the percentage of time spent in electrode negative polarity within a single AC cycle. Each AC cycle includes time spent in electrode positive and electrode negative. We hope this helps, let us know if you have any other questions.

[@PaulBrown-my6ts]

I have the same question since my cheap inverter TIG machine doesn't have an adjustment like that nice new Miller....But you really didn't give a clear answer to that question Andreas asked.... My machine and I am assuming his machine as well, has a dial that show 0 at the top center and then negative - counter clockwise and positive + clockwise, so 75% would be the amount of Negative polarity spent?? And would the negative side of the AC wave balance tend to give more cleaning action or more penetration?? Been TIG welding off and on for years, but never with these newer inverter machines. Thanks

[@derekcollins1972]

He has dreamy eyes.I'll take 2 of whetever your selling.

[@Andy205ro]

@marek0086 NO...Giggity Giggity Goo!

[@tboost007]

there really needs to be better international standards for this feature on all AC tig machines.. i find it really irritating that every machine operates differently.. its not rocket science.. and in this video you didnt mention how the % relates to EN or EP for the miller machines. It makes no difference what the brand is, the functional standards should be the same for all brands of machine.

[@RoweroMacka]

And what if i have black spots on puddle and i should make balance down, but at the same time i get my tungsten melting to big ball ? Should i change tungsten ?

[@dougankrum3328]

+RoweroMacka Black spots, usually dirt or touching the tungsten to work....tungsten balling up...go larger on the tungsten, you get up to 5/32", for the larger torches 3/16"...

Pongan subtítulos en español

[@heidibooth2088]

you will always want to clean you rmetal prior to welding :)

[@MillerWelders]

@andy205ro and @marek0086 - If so, lame attempt. Keep it out of the gutter, boys. And yes, have a great new year!

[@AC-yi3qb]

[@jacobjames1171]

There's no need to prep your aluminum prior to welding. Adjust the balance, and you'll be on your way to quality welding. For the real grayed salty looking surfaces you'll want your balance closer to 30%. Good luck with that.
