Welding Tips and Tricks

At my brother-in-laws for the weekend, he works for a cattle rancher in the middle of building a newer feedlot. The rancher uses all rusty oilfield stem pipes and 1” sucker rods for the fencing and it is the rustiest crud I’ve ever seen. He bought a brand new MP210 for this, threw it into a milk tank along with some C25 and pulls a generator behind the tank. Typical rancher.

This kind of workmanship bugs the heck out of me. He uses 70-S6 solid wire, I’m guessing Innershield might work a lot better for him. Or should I recommend 6011 instead?

Either gasless flux core or 6011 would work. The porosity is likely from the C25 shielding gas being blown away by the wind. So technically ER70-S6 solid wire will work, it's just tougher to utilize properly in the outdoors.

A new MP210 comes with a small roll of flux core and the knurled rollers. So I’ll set it up for him to try, I’m sure it’ll work a heck of a lot better than solid wire with gas in the middle of a windy field.

must have a generator of some type along for the ride. clean up the rust a bit and purty up the welds with flux core.
AND just what the sam hill is that white crap in the background??

Yep, he hooks the genny cart to the back of the tank cart, chucks the welder in the tank, hook the whole train up to the side by side and off he goes. Guess there’s more than one way to skin a cat

White stuff is what rain looks like in Canada for half the year.

No, but I can imagine. As for the welding, needs a wire buffing and stick or gasless flux. It can be rusty, but not flakey...

yes. i would not even bother stuffing around with a mig on a job like that, even fluxcore.

Well I feel like a kid who just realized he had a depraved childhood. I’ve fiddled around with an old roll of ss flux core off and on, but the last couple days I decided to really get into it. I never even had a knurled drive roller for it. So I picked one up, switched out my little MillerMatic 175 and dove into and mine I am pretty darn impressed. The amount of metal i could lay down with a little machine like that was pretty eye opening. Can only imagine what some 1/16 wire in my PowerMig 300 will do. I’m still struggling with welding anything uphill with mig and stick but with this it was easy, it works like a dream out of position.

I’ve only welded 20-30 mins with the stuff so the welds aren’t Instagram worthy but I’m pretty stoked. Will definetly make some future projects a heck of a lot easier.

Looks good Jay

Jesus, Those are some rough looking MIG welds, flux core is the ticket for sure, 6011 would do just fine, but anyone that would default to c25 MIG welding isn't the type of person that ought to be stick welding uphill.
