Not very good, he was running it to hot for 14 ga.to much under cut not uniform. should have welded a little faster. Keep practicing, you'll get it.

@Mokdo68

Thanks for your tip and advice.

Here's a dirty little secret-This application can be easily MIG welded! All you need is a simple, economical, easy to use CV power source, Ar + 2%CO2 shielding gas, and a 1mm 308L or 347L wire!

In fact, TIG is much less desirable, due to the unbelievably slow speed, excessive heat input, and high operator skill required. Good MIG parameters are 350 inches per minute, 17-18 volts. (I'm not sure how that converts to meters or centimeters per minute. )

Also the parameters do you recommend, 350 inches per minute (8.9 meters per minute) is not possible use in the joint 14 Ga. (1.9 mm), which I am welding in my video. This blend Ar + 2% CO2, have a poor bead contour.

Thank you for watching my videos

Greetings from Brazil to you.

I think I was rude in my reply to you because all the welding processes are important, depending on the base material, weld joint, number of parts, welding position. TIG / MIG / SMAW / Oxiacetilene Welding, Torch Brazing may be the best choice. Thanks

Hi, u need get a pulsed mig for stainless if ya wana do it quick i could do this same piece in seconds with the pulsed mig + argon 2 percent CO2 mix, 1mm 316 wire,no spatter just a quick wire brushing after n its bling, plus nice and uniform.

@hybelkan1nen no it depends on your welding speed not the amps,greater amps means you have to faster with your hands

[BrazilWelds]

@hybelkan1nen Hello friend! The stainless steel need approximately 80% of the Amps that are used for mild steel. For example: MILD STEEL. BUTT JOINT, METAL THICKNESS = 1/16" (1.59MM), TUNGSTEN ELECTRODE 1/16" (1.59MM), FILLER ROD (If required) = 1/16" (1.59mm) - SETTING 60 - 70 AMPS. For the same situation but, in the STAINLESS STEEL MATERIAL, SETTING = 40 - 60 AMPS.

I believe that Ar/2%CO2 is a "low energy" gas mix. The lack of reactive gas reduces the weld current for any given wire feed speed. The poor bead contour quite simply is results from the lower heat input compared to more reactive mixes. BUT, for something as thin as 12Ga, lack of weld energy is not usually a problem. To compensate simply increase WFS, volts, and travel speed. It is my understanding that it's not advisable to MIG stainless with more than 5-6% CO2 due to carbon pickup.....

[TSorovanMHael]

@BrazilWelds Yeah, you're right. If weld appearance is of vital importance, also lack of spatter TIG is definitely the way to go. It wasn't clear to me in the video that appearance was the reason you are using TIG.
