Greetings from the Napa Valley. What a great video. Love the great detail provided. I'm retired from the bay area oil refinery's and still like to tinker with my wire machine .My old standby is knowing the difference between a new born baby and a welder ANSWER the new born baby will eventually stop crying. Anxious to try my brand new Esab emp 210 three in one machine. May need to stick something or mig nothing of a large scale but would be handy for small tinker jobs. My eyesight isn't good enough for tig im now 79 going on 80 .32 years as stick pipe welder. I look back and remember being under pressure to keep my certs up every year a lot of stress. Got COPD from not being aware of dangers from asbestos. Pleas us all your safety gear so when you get older you will have a better quality of life during retirement. Thanks

Interesting and well done. We always adjust values to get the best profile, but in this case you didn't. This is good information for today's market when they ask, "Where can we cut costs, and with what result" A shop with 15-20 welders pushing out garbage/recycle bins are looking to cut cost at every turn. Someone creating items that have a higher visual appeal may not only choose the more costly gases but even a different process.
For my little garage shop, it's Flux core, Co2, or stick for ferrous metals, and sometimes its a combination of them depending on position, root pass, fill, or cap. For example 7018 root, MiG fill, 7024 cap.

If you used the same settings for both, one was not run optimally. My machine recommends to run higher voltages and wire feeds for CO2. The beads will lay flat with a little oscillation. Look up the door chart for a Lincoln 180T

Thanks, as a hobbyist I needed someone to show me why I can use 100% CO2 instead of C25.

Top notch content, you do a great job breaking down pros and cons!

[Welder]

Voltage setting will typically decrease with the introduction of argon....co2 will need higher voltage to run as you pointed out spatter is a negative biproduct of co2 for sure along with narrow profile.

Great to see this after reading articles about welding gas theory (and opinion).

Great video. I am learning English and how to weld. Thanks to you I can learn two things at once. Thanks dude. 👍🏼👍🏼

Did MAG/MIG welding course for work many years ago, we just just used argon Co2 mix for steel but instructor said Co2 can give little more penetration with right settings . We obviously used just argon for alloy and was surprised how easy alloy was once you got rig set up correctly, did have go with pure argon on steel, got great looking weld with bugger all penetration though

Very good video. Now I know what connector to use from my Co2 tank to the Argon gauge. Thanks a lot.

Appreciate the tutorial 101…. Was on market for mig welder. Been arc welder for years. Realized mig might be better way go to build things.

Great video as always. One advice- turn off autofocus on your arc camera. Your camera, or any camera for that matter, has hard time focusing through the dark glass. Pre-focus it manually before striking the ark.

First of all; this video was well done and i watched the whole thing. But your CTWD and work angle will have much more affect than the change in gas. All that needs to be constant during the test - like robot constant. What i can share is argon has a lower ionization voltage, and therefore lower power input. Further, more argon will allow spray transfer at lower amperage. So you can expect better bead appearance with argon, because of finer droplets all thru the range 👍 the richer you run the argon the higher your wire feed can be. More C02 will help you in out of position welding

Awesome video, very informative as far as the information I was looking for. Thanks pal!

[randomschittz]

Damn, glad I clicked in this video or I never would’ve learned from all the professionals in the comments

[davidjanuszewski]

I like the welder shield, sure gonna lengthen the life of the plastic parts, those UV-rays are a killer.

[Marilynthepigeon]

Greetings from Germany, great video and advice. 😊

[davidhoover]

Damn Dude, You weld like a robot. Nice job!

[moemoes]

that nice arc shots, I could actually see the technique that you were using.

Make sure to use the right respirator cartridges Alway but Especially when you are putting acid on something hot.
