>a quality day working on a SubArc running around 800 amps
Take a coil spring, like in the front of an old car, but 3 feet lonf and 12 inches wide.
Stick it in a heavy wall pipe, and squash it with a 3 ton press.
SubArc weld a circular plate on each end of the pipe.
*Pray* that the machine was set to the correct table hight and overlap
Release the press with the spring trapped in the can.
You just made a nuclear reactor componant
When you hear the *pop* because the plate was held on with slag instead of a weld....
Run like hell!
So, how long did you work at Cat's Cylinder Plant Rusty?
Did an old fart teach you that trick?
Were you still a broom hand when you learned it?
It's OK, you can fess up, CAT pulled SubArc out & scrapped the machines 10 years back and replaced it with spray MIG.
Then they retired all the old SubArc hands, because the young Welding Engidunces said the old farts couldn't handle the new process.
Then they brought in Plasma welding machines to fix the bad MIG welds.
Then new Welding Engidunes came in to solve the rejection rate on cylinders, and all those nasty warranty return cylinders.
They sold the Plasma welders & bought new MIG machines.
Rumor is a couple old SubArc hands have a shop that does nothing other than delouse CAT cylinders.
