I've been a professional welder for 40 years, miller are top notch. I'm mainly a tig welder, I've done oil exploration ballast tanks for submarines recently, all aluminium, I'm now making bespoke 304 food industry equipment, all hand made, look up Gough engineering UK. That machine is excellent, but uphill should be slow and patient, with the torch pointing slightly north. The backwards Z trick is to watch it sink on the left corner, let it rise then move right, same again, then z up to the left to create the second part of the weave on the left and so on. It creates a double bead, with full penetration. I used to weld cut and stretch wagon chassis like this, with hiabs on.

Another great video, thanks, Jody!
Just to chime in with over 45 years of MIG experience on the "Push vs Pull" technique w/ gas shielding.
From back in the day, in the Navy and Oil Tanker shipyards working w/ Steel and other shipyards MIG welding all Aluminum Tuna Boats w/ "CobraMatics", we were ALWAYS required to Push a wire feed whenever possible for a number of reasons having to do with penetration and porosity.
This is because as the nozzle is angled slightly in the direction of the weld, the shielding gas is pushing the atmosphere away from where the puddle is going to be created.
It was determined that a "Pull" technique, with the nozzle aimed back towards the puddle, opposite the direction of travel actually placed little gas coverage in front of the puddle and the weld force tended to "suck" more atmosphere directly into the formation of the puddle as the angled nozzle moves away from the weld.
I know it's Po-TAY-toe vs Po-TAH-toe, but except for real thin material or difficult circumstances, I still "Push" when ever possible based on 45 years of experience punching the clock in the yards and later, owning my own fabrication business.
And Jody, Thanks again for ALL you do for the fabrication community!!!

Jody the metal god !.. I bought this machine trusting your honest review.. And I could not be happier with my purchase .. thank you so much for your invaluable time !

Thanks Jody, awesome video. I just ran into this same issue and now have a much better understanding!
The “Mig Knuckle” works, it’s awesome!!!
So just an update, I am about at the 2yr mark on watching all your videos! Just love them. Be Blessed!!!

Got to check out that mig knuckle, i was actually just using my tig finger xl not to prop but to shield the heat from mig welding my trailer. Funny how things work out. I guess all us welders experience the same things. Burnt knuckles, and holy boots.

I just recently purchased a millermatic 255. While trying to familureize myself to the new welder
Did the push then pull then the vert down and then vert up with the auto settings for size of steel, gas and wire. I got even an uglier vert up. Now i know how to correct that. Thank you Jodi for sharing your welding expertise. I have Been welding 55 years plus. Age has deminished the eyesight and i no longer want to weld out of position. I' m to stiff and feel like i have fallen and cant get up. But as long as i can move im going to continue to go to the shop and enjoy the challenge. Still fun to learn and perfect what i think i know. My dad had a mobile welding service till he was 80. And lived to go weld something. His mistake, he retired.

Super instructional video Mr. Collier. We appreciate all the information and time you dedicate to us all.

[fredalmond]

Cripes just realized how much I've learned from Jody and his videos. Making super good use of my everlast welders and enjoying every minute of it because of this gentleman.

[godlyintellect]

insane movement precision, love the technique. thanks a lot, great video as always

[harleyryder]

Jody...you're a great teacher...love watching your videos ...I've been welding for 20 years...and still fascinated by the craft

[tylergordon]

I love how your products are no bs, simple designs that fix problems.

[liammiller]

You are a true craftsman and wonderful teacher. My skills with my everlast welder are so much better since watching your videos.

[antoniobello]

Your technique is very good is the first time I see someone who explains it well.

[richardsmart]

So much knowledge and so willing to share. I love this channel. I see that Miller is trying to catch up to some Everlast innovations. Very interesting to watch the technology mature in welders.

[cameronnerdin]

I LOVE THE IDEA OF A KNUCKLE PROTECTOR!! I will have to buy one. I use to cut up fiberglass protection tarps, now you solved it for me.

[grumpyone]

Thanks so much for all your welding tips. I’ve always struggled with vertical up with ugly looking welds. Probably because I never turned the power down thinking it wouldn’t get in there as much. Turns out that’s what I should have been doing all along. I’m going to practice some more to try and nail this technique once and for all. An appreciative UK viewer.

[mxdev]

Thanks Jody, I've been having issues with uphill on my MM211 at home, and hadn't had a chance to read up on proper setup yet. This gives me something to try and get uphill figured out.

[joesminis]

I am learning to weld and have watched all your videos - even some multiple times. Very, very helpful.

[idriwzrd]

So much good info packed into an easy-to-follow video. Thank you, Jody.

Got to try that technique out. Just bought a Miller Multimatic 255 a few weeks ago. What an amazing machine! Replaced my Lincoln 180. That Pulse Mig is freakin awesome!!! Really excited to try this vertical uphill tomorrow. I’ll try it on short arc mig and pulse mig. Pulse mig seems to work better on everything I’ve tried so far.
