I got a nasty little job. The joker that had the backhoe before me tried to
repair the loose pin by just reaching down inside and welding on the pin. He
did a real shitty job and just made it damn near impossible to repair right.
(BTW, I unbolted the top pin on the same side today, it fell in two pieces,
the pin had stress fractured all the way through. I don't know why the hoe
hadn't already fell off the tractor)
Anyway, I need to cut a 1.5 inch pin in two reaching down inside the hoe
assembly along a crack about 3/4" inch wide. There's not room for the torch.
So, I was talking to "the kid" about how to do this and he reminded me I had
bought an air arc rod holder and air arc rod at an auction years ago.
Anyway, I found a rod holder that also plugs into an airline and blows an
air jet down along side the rod. I also found a few rods labeled "Accate
Jetrod" . its brass color tube about 1/2" diameter O.D. by 3/8" diameter
I.D. with a black filler material. And half a box of solid brass color rod
labeled "Arcair Copperclad". Both rods are very light - I suspect made of
There. that's all I know about air arc cutting. can anybody fill me in on
how to use this to cut my pin? I have an Idealarc 300/300 AC/DC/TIG welder.
