Push vs Pull: Metal Core Edition
Вставка
- Опубліковано 7 лют 2025
- We tested spray arc MIG. We tested gas shielded flux core. Now we're testing metal core for the trifecta! Once again we are running a push vs pull on a robotic system to take any human error out of the equation and doing a cut and etch.

Such an under-rated episode. This is some super valuable information... Thank you.
In deep bevels I have used a pull method for the root and then switch back to push once the groove gets wider and the wetting action of the metal core gives better deposition
Passed many many x-ray and ultra sonic welds using this method where others have failed on the same joint using only push
This series was a great controlled exercise loaded with need to know info and if we didn't learn something it's our fault. You are doing one hell of a bang up job and have push your channel to the top, along with Jody's tipsntricks, of all the welding channels out there. GOOD JOB!
Lee Barnhart thanks for your support. We have a lot more good stuff coming out soon.
Great timing for this video. Tomorrow I'm using Blue Demon hard facing wire on my FEL bucket and would have dragged it since it is metal core with gas. I presumed metal core was similar to flux core and should not be pushed. Now I know to not drag it and I like the wider bead profile which will improve the function of the hard facing.
Brian G C if you’re doing some hard facing check out Select Arcs Wire. They have some really smooth running stuff for hard facing.
This is superb information!
rlund3 thanks for watching.
Great demonstration! Very informative!
This was a great series 👍
Beach&BoardFan thanks for watching. We’re glad you enjoyed it.
Would you guys do a metal core vs flux core video? I'm curious as to why and when you would use one over the other?
Beach&BoardFan we’ll add it to the list. Thank you for watching.
loving these new episodes, upping the ante buddy!
Great stuff , hoping yall do an episode of standard short arc with a push or pull travel angle!

In the late '70's, about all we were taught with wire was the push technique. We also didn't use backing plates for our test coupons back then either....
Awesome video!!
Jim Miller thank you sir.
Couple of things, would have liked to have seen robotic welding with sine weave on this wire test. Also this wire is awesome for speed and productivity, but really tough on liners and tips. The outer skin of the wire is much harder material have to be careful on the amount of tension you use on drive rollers. You can get it out of round with excessive pressure and have premature wear out of tips and gun liners.
Michael Rust maybe we could do that in a future episode. We just wanted to show the difference in technique for the average user doing a handheld application.
This confirms my theory of pushing when Mig/mag welding
Only on metal core wire.
Been using metal core wire for 30 years. You will never run hard wire again if you use 1 spool of metal core. You’ll kick rocks at hardwire. Seems like it’s taken a couple of decades for some companies to see, understand the benefits of using metal cored wires. I know some places are stubborn and want to stick with what they know. Unless you’re going vertical up at a hot voltage setting like you would with some flux core, a metal core wire isn’t equaled. And I know this is for educational purposes but only time I’ve ever seen someone drag a mig is when they had no clue what they were doing. Push it real good
I noticed that the contact tip was about 1/8 "out. Normally, when we weld in spray mode, the tip contact should be inside the nozzle.
Why is he so much out?
Does this falsify the data as the terminal length (Electrical stick out) is shorter, the amperage is automatically higher. So the penetration will be higher too. Why does the contact tip come out of the nozzle?
Peter Welder with this wire at .045 a 1/2”-1” cttwd is what’s recommended. We were right around 5/8” of an inch on both push and pull so that the amperage would not differ between the techniques. This type of nozzle is pretty common, it’s just user preference. There are several types of nozzles available for different applications such as flush, recessed, exposed, slip on, tapered etc. it all depends on what you like. With the appropriate shielding gas flow it shouldn’t have much of an effect. ESO isn’t as important as Contact tip to Work Distance because that is what ultimately will cause fluctuations in amperage.
@@GodslilRedneck23 Can you make a video concerning different types of nozzle ?
Peter Welder I can make sure it gets added to our list for sure man.
@@GodslilRedneck23 thank you. i follow you. :)
Peter Welder thanks man, I really appreciate all the fans, followers and subscribers. You all are the reason we do what we do.
Goog work
Which shielding gas mixture did you use? Ar-CO2 or Ar-O2? Nevermind, I saw it in the comments, but I was initially looking for it in the video info. Great videos as always.
So would this be for industrial uses or can say Harry home owner/ part time fabrication dude use this on his small shop?
madcap magician Harry could definitely use it, but for the average hobbyist I’d stick to solid wire. The metal core is great for production welding as it yields faster travel speeds and greater deposition compared to solid wire. It’s a bit more expensive compared to solid wire so not much benefit to the hobbyist. But due to increase in productivity the benefits would offset the cost for a company.
@@GodslilRedneck23 ok thanks for the info 😁👍
Another wire? Damn it, now I have to try it........😂
So where is the Push vs Pull using the most common wire ? Solid Mig Wire ?
Good series, , can you mig weld double pulse with metal core wire ?? 👍👍
FlashTechEngineering you mean pulse on pulse?
Yes pulse on pulse mig welding..cheers David
FlashTechEngineering I honestly don’t know man. I’ve never been in a situation to try it. I do know that it is used in the automotive industry with robotic applications. I don’t see why it couldn’t be used in pulse on pulse. I know it can be used in a pulse spray applications so I would imagine it would work.
Okay thanks for the reply, I'll do some research 👍👍
Was was thinking that guy has the steadiest hand I’ve ever seen, then I saw the robot. Haha great tips! Can metalcore be ran in hardwire mig machines, or is this a specialty rig?
KTC Garage typically want to run it in pulse mode.
Me too! Figured it HAD to be a robot and then it was confirmed. I was ready to give up if that was welded by a human!🤣
id like to know which gas mix you used for your test with metal cored wire
Peter Welder for this one we used 75/25 but you can use 85/15 and 90/10 as well.
Ok I'm confused, no gas? Or flux??? How does this work?
Not sure why they forgot to include that info. Yes it uses a gas shield. Run this type of wire at work on robot and manual welding. 90-10 gas 25-30 cm is what the mixer is set at. Another great benefit is very little splatter. Easy cleanup for our Slager crew.
@@michaelrust7614 thanx for the info👍
madcap magician for this we used 75/25 Argon/CO2 gas. The inner core is made up of 95A% iron powder, it doesn’t produce slag.
@@GodslilRedneck23 ok thanks for the info 😁👍
Gonna make sure my everlast gun is pushing whenever possible for metal core now
PHHH ff Run some .68 all day on tar coated fuel line! Ahhhww Spray Arc loved the heat! ..?345 amps .035 roots..s7 soild
where bob ?
We use 1 and a 16th wire and its really annyoing to use.
What's the most dangerous animal in the world? A robot loaded with Metalcore.
But a robot is not an animal.
Robotic welders (not an animal) are only as dangerous as the programmer and operator (both animals) who run them.
House cats are
Slinky corn ....Hahahahaha! I stand corrected. I've got one of those beasts in my house too. Don't know how I overlooked that! lol
nice!! 💪 👷🏻
Where is Old bob Moffat?
