Oh lordy, the states of some stuff.
Understand everyone needs too learn, but bugger me.
I'm (was) coded welder for Alstom, generally borrow a nice little jobby off my mate. Last time I borrowed it, my god the settings were well off.
One of them things you get a 'feeling' for.
Set it up and the numbnuts who had previously borrowed it, had clearly had the wire speed down, and burning the tip. So instead of turning it up, in infinite wisdom of stupidity, they'd just cranked the rollers down.
Some people should not be near a welding set.
Reminds me of my college years, when a stuck up arse teacher from secondry school, came in on open night saw me, and pretty much demanded '5minutes to learn how to weld.'
He promptly got told to sod off.
