Worst prank EVER
So I broke a wheel off my lawnmower, no big deal, just weld it back on. How was I supposed to know that a wooden stump would break it?
Anyways, since i have a shitty flux core mig welder from Harbor Freight, I decided I'd ask a friend to use their gas mig to fix it. I bring the lawn mower over, bring the welder outside, clamp the wheel bracket back on, and start the weld.
All of a sudden, there's a huge ball of fire all over my mask. I immediately stop welding, and jump backwards.. yelling out, while he sits there on the ground laughing.
He switched the argon with acetylene, at 10psi. Not cool. It was hilarious, but not cool.
