Machines | Farm Welding Repair: Rebuilding a Trailer Hitch
videos | at work | information | view | construction
Miller Product Manager Ben Romenesko performs a Flux-Cored weld repair of a broken trailer hitch at the Johnson Farm in Northern Illinois. Ben uses the new Multimatic 200 powered by the Bobcat 250 and describes proper settings in this application. Please note at the 2:05 mark: The machine should be switched to straight polarity (electrode negative), not reverse polarity. Ben's next statement -- that the drive should be in the negative and work lead in the positive -- is correct.

@2:05 My students caught it when he says you need to switch to reverse polarity and then sets it up correctly with straight polarity (electrode negative) for self-shield. Whoops... glad my students are so well trained though!

I weld farm equipment.
it's never a deal where you got a bunch of time to do what you would really like to do.
it's not a job for the welding snob. the welding snob won't lay under a county snow plow in slushy wet snow at midnight to get the job done.
that same snob and his book of safety stuff would crap their pants from likely broken rules watching me cut, bend, and plate a combine head in a dry corn field. -
@ 2:36, I know that I saw a Bic lighter and you prolly used that for light the torch. So being an OSHA/MSHA inspector I feel it is required to give a fine of $ 1,000,000. that should make every thing safe.

The center world looks kill crap. It is incomplete, has a hole near the top and is not wrapped on the ends. As a journeyman you would be told to fix it and if poor workmanship occurred again, you would be fired from any job shop I have ever worked for.

come to our barn and weld rusty gat and other rusty thing that is real farm welding
-
A genuine miller disgrace....
Ridiculous to use $6000 of welding equipment to do a simple repair like that!!!
Poorly welded, but what do you expect from a "product" manager.... He can't weld!!
Lincolns from here on out!!! -
I liked the video. It basically is what a "real" farmer would do and NOT a professional weldor! Some people are just way too critical here in this project. Those welds could have used a second cap pass, yes. However, I'm betting that repair job will "stick" and stay put for what it's used for. People need to step-off and not be so dang critical all the time.
-
sorry.. but if that was the best welding I could do ,,I wouldn"t weld..
-
Some of that needed a second pass...
-
flux core is ALL 71 series electrode. 70k psi steel whether 7018 or 71 flux core. in brief, you really are performing EXACTLY the same weld joint as far as chemistry, strength, and serviceability is concerned, just with the speed and convenience of wire feed. the only caveat to that is if you are working to an engineering spec for a particular process/electrode combo. then a variation without authorization is a "technical no-go", even if the particular joint meets load handling spec.
-
also how would he connect it as well to the tube? since i saw both plates were welded directly to the tube....
-
For something high stress i would have definitely used 7018 that plate has to put up with ALOT of stress.
-
I would cut the plate to length tack one side on use the torch that was used to prep the piece heat the middle and beat it around the piece. But hey either works fine I do believe I would have ran a weave over those beads just to cover my ass
-
Thanks for showing me around yet I still know how to weld with my machine. . . I was introduce to a farm bureau and currently working on my real estate license in the state of California . . .

Salesman welding?
-
hey really like the miller kit but to be fair if that pin sleeve came out before it prob will again with those welds! Believe me if its being used by a farmer it needs to be stronger than that!! Maybe miller should get weldingtipsandtricks to do the demo's at least he can weld!
-
continuation, and just a few welding electrode, surely you must be having enough tools in your truck.
-
You will need some tools to bend, however it seems the plate thickness is hardly 3 to 4 mm. I dont now inside your truck you have a the tools to hold one side of plate, if you have then just using two wrench spanners big size, you you can bend the plate. or if you have gas welding equipment in your truck , heat the middle section and bend it. there can be numerous way to bend that thin plate , you need to have tools in your car. I dont think inside your truck is just welding machine and cont.
-
Good suggestion. So how would you bend a plate that thick to match the angle needed here?
apt representation of miller products!
