Reply:I don't know. My Case backhoe has the words cast in several places DO NOT WELD. I have a friend who doesn't read. He welded his with a Lincoln buzz box AC tombstone welder. It is a crude looking weld that has held up years without crack.An optimist is usually wrong, and when the unexpected happens is unprepared. A pessimist is usually right, when wrong, is delighted, and well prepared.
Reply:Where's the guy with the thread asking how to weld the Case backhoe boom that was broke all to hell?  I still have never seen one that bad. I can say with absolute confidence er70-6 is a no go. Even on kill mode. But hey, when your desperate (really bad desperate) it's worth a try and looks great. For about 20 minutes. "You can't out puke a buzzard"

Reply:For ductile iron piece parts the "do not weld" basically means you will void any warranty if you do .. But once it is past warranty and broke or wore out you're choices are weld it or buy new so you're in a situation where welding is worth a shot. Try it and if it works it works, if it doesn't then replace it. For a "corroded surface" I dunno, it depends is the answer."The things that will destroy America are prosperity at any price, peace at any price, safety first instead of duty first, the love of soft living and the get rich quick theory of life." -Theodore Roosevelt
Reply:Originally Posted by Willie BMy friend from the city has a vacation place near me. He loves running machinery, and though not very good at it, rents frequently. I learned a long time ago I'd be better off paying for a rental to loan him, than loan him mine. Stuff gets broke. One rainy night he called. "I broke the shiny thing on the front of the excavator"I went to investigate. The bucket cylinder rod was indeed broken. It was first bent at about a 30 degree angle. Upon closer inspection in dark, and rain I discovered the dipper was also broken, hanging on by the now bent leading face. The break surface was fresh. Next morning he called again to say he chained everything up so he wouldn't damage anything else. "How are you going to damage anything else?" "I'm using it for a bulldozer."An hour later he called again wanting to know where to get hydraulic hoses made. His blade full of boulders was too tall. One tumbled over the top of the blade.
Reply:I've had to come to a hard decision. Some people aren't allowed to borrow. It must be recognized that even a skilled operator on worn equipment will have breakage. The cycle goes A. use it, B. break it, C. seek the skill to fix it, D. seek the parts to fix it, E. crawl under it in mud on a rainy day to discover the part is wrong. F. repeat part C,D,E, G. fix it. Repeat steps A thru F. Step A never takes long, B through F take time. During this time I can't use my machine. None of the borrowers I've met are interested in participating in the steps following A. This same friend understands he is incredibly inept. He once borrowed my old tractor to bush hog his meadow. As it had a loader, he decided to drive down the highway a few miles to get a marble block to use as a door step. Instead of putting it in the loader bucket, he hung it from a long chain. It seems the entire trip he drove with it swinging, banging into the grill like a wrecking ball.Like my kids, I don't disown him for acts of stupidity. I do however try to learn from bad experiences. Hence the rented excavator. He once rented both a track loader, and excavator, he was digging boulders out of his meadow. After breaking the excavator he discovered that one fork on the CTL worked reasonably well as a giant crow bar to pry boulders out of the ground.An optimist is usually wrong, and when the unexpected happens is unprepared.

Reply:many a back hoe welding job is somebody borrowed it, broke something and has it welded before returning it..obviously somebody spending $200. to weld it is to save spending $2000. for a new part to replace broken one.
