I've had it happen a few times, usually when the can pressure is almost gone and i might touch the tip for a split second (were not changing the gas cans/flasks before completely drained and unusable..... Not my decision!) And always rapidly shut off the gas, wait a few seconds and turn it on again to purge and see if the flame has gone out, it usually spits a black cloud and nothing more and then check everything for heat. I've also heard a coworker doing it several times but they never shut off and just continue using it wondering why the flame is weak before i scream at them to shut it off 🤣 When i started in the company the hoses and whole setup didn't have any flame arrestors! Only backflow preventor, i quickly demanded new hoses, gun and flame arrestors when changing the hoses it where completely black inside the acetylene one..

There was no flashback arrestor installed at the cylinder gas regulator.

Awesome Product Sir.
