Last year I bought a Lincoln 240 amp arc welder at an auction. I dont know how to weld but it looked like a good deal so I bought it. I got the welder, face mask, wires, and 20 welding sticks all for $250. Last fall my neighbor borrowed it and welded his kids swing set, and it worked good. Last weekend I asked the neighbor to come over and weld my fence gate hinge that someone hit with a car, and weld the hitch on my trailer that broke off when the trailer tipped over. My neighbor used to weld for a living, and he welded trucks and bridges, so I thought he knew what he was doing. He welded the gate and the trailer for me. On the trailer he added some angel iron to make the hitch solid. It looked great when he finished. The next morning I came outside and found the fence gate hanging, and the trailer hitch laying on the ground with the angel iron pieces laying in a pile on the ground. I was really pissed. He spent over 4 hours welding, sent me to get more sticks from the hardware store, which cost me almost $20 for 10 lbs of them, and he used half of them.
I am really mad about this. I expected this to be done right. I took the welder to a Lincoln dealer and they said it was working fine. I went to the hardware store and complained about those welding sticks, and he said they have never had a complaint about them. He did tell me that the guy probably did not use enough hardener in his welding job, and did not let the weld dry long enough.
So, who do I blame. This guy is supposed to be a professional welder. He is retired now, but I would have expected he knew how much hardener to use and how long to let things dry. His swing set worked fine, but not my stuff. I am very frustrated about this, and have been too angry to talk to him about it.
Before I talk to him, I want to know how long a welding job should dry, and how much hardener should be used? I never saw him using anything besides the sticks, so I wonder if he never used any hardener. Can anyone help.
Thanks
