When it comes to mig or tig it doesn’t matter if you’re going up or downhill, there’s no flux to get in the way and that molten metal don’t care if it’s going up or down
Pretty dope my dude. I had to see it to believe it. And its wild to me. Open Roots all day can be done with short circuit mig . But its wild to me, seeing thicker plate not have lack of fusion in the side wall. I know folks have procedures out there in the wild . But its just so hard for folks to get GMAW-S to weld repeatedly over and over and over with out failures in thicker bits , after an open root. Very rad my dudes, I have failed a lot GMAW-S welds that where in thick plate . It was super rad to see one passed. Now I am going to have to go try one after this outage I am working .
Great video, I just spent 16 weeks at local MIG school and cert'd on spray transfer. Nice to see the results on short circuit up and down hill. Always learning....good stuff!
I feel like this channel has gotten a long way away from where it was when Bob was doing the presentations. It felt organic, simplistic, and got the point across without any filler. The videos now all feel so flashy and fast paced with all of the jump cuts and edits.
Austin, you never mention wire diameter , at least up to 7:38.....We think that may be helpful for your viewers..... otherwise, great information here......hope to see you at Fabtech......cheers from Orlando, Paul 'Paulie' Brown
Hi bro I am also fabricator mig welder spray painting sand blaster last 21 years experience in india gulf country Saudi Arabia Abu Dhabi Iraq so I need job europe country please help me I am waiting for your response 🙏
Man I work in a production shop we run mig and flux in everything from 2 1/2 inch all the way up until 14 inch and then we do mig and sub arc all down hill beads and pass cray everytime
9:43 he mentions bumping up the heat a little bit by raising the voltage from 18.5 to 19 volts, and then bumping up the wire to match the voltage, I thought amps were the heat input in welding, like stick or tig, and the voltage was the force behind the arc to jump the gap ? does mig not consider amps to be the heat ? or am I missing something......thanks in advance, Robert
@@dotark the amps are not the same as wire speed, due to the different thickness of wires.....only .045 wire is a direct translation, 100 ipm equals 100 amps.... .045 at 100 ipm divided by 1 = 100 amps .023 ipm is divided by 3.5, .030 ipm is divided by 2 .035 ipm is divided by 1.6 [160 ipm = 100 amps]
@atomichydrogenweld2823 thank you for the fix my comment was poorly worded and I kept it to simple. What I should have said was wire speed correlates with amps. More amps more wire ( and a colder weld because to much filler to fast. Not the best way to cool a weld but it can) this is why even on the name brands like Miller and Lincoln you will see some wire feeders use wps for wire speed and some are labeled as amps
In 2010 I welded a 150x150x10mm square tube frame with a 200 amp cheap mig welder, which houses 6 water pumps and filters and has two cooling towers with fans. It ran and vibrated 24/7 for thirteen years till the factory upgraded. All welded downhill and no welds ever failed. I only welded it downhill because every time I tried uphill I ended up have wire feed and burnback issues, so I set the welder to maximum and did it all downhill moving fast to stay ahead of the puddle.
Uphill or downhill, either works great. In 34 years of mig welding in a pipe fabrication shop, never had a problem running downhill on roots.
1000 percent
Thanks. Great content and the proof was in the pudding! Just as good when done correctly👍🇬🇧
Thanks for watching!
Both are good,but downhill is harder to master. Cold weld is a real problem with downhill
@@ReBeksonn it's quicker and easier imo when you getbthe hang of it
I would say downhill is easier, you aren't working against gravity.
Depends on thickness, as long as you get adequate....... yea.
As a non-professional welder, this is a really good explanation of up hill and down hill. Hope you both are coming to Fab-Tech. Great job gentlemen.
We both will!

Biggest issue is carrying to much metal. As long as you watch it. Like you say, all is fine

New to Mig welding informative video,i just bought a Mig welder it only has voltage and Amperage knob how do i know my wire speed?

great video guys,,,,,,loved seeing those bends....
I was surprised at the low voltage. Good to know, i will definitely try that.
Give us a real test not just bend test. Make a lab test
Don't even wave to watch, the answer is no, but yes.
Now bend the roots without any other welding done.
Thanks for sharing! 👌👍
great video! great work!
Uphill makes some sense visually, but minimal difference if any in strength of the weld.
Same wire and same basement, same strength.
No, but yes
9:43 he mentions bumping up the heat a little bit by raising the voltage from 18.5 to 19 volts,
and then bumping up the wire to match the voltage,
I thought amps were the heat input in welding, like stick or tig, and the voltage was the force
behind the arc to jump the gap ?
does mig not consider amps to be the heat ? or am I missing something......thanks in advance, Robert
no with mig and flux your amps is same as wire speed

Learned to never weld downhill bc it wont hold
You just watched it. Just can’t carry as much metal
