(I'm studying welding and steel fabrication in a training program for the unemployed. And I love it!) Anyway.
These are full length 3.2mm OK48.00 rods (450mm long) rods, that have been ignited once to bridge then discarded. (They cost about 40€ a packets of 124). Sometimes if I am too lazy to sign out a fresh packet I just go to the waste bin and gather about a bucketful of these and return to my booth. They are perfectly functional and dry, to ignite perfectly without issues! And everyone gets taught the first lesson how to reignite and burn these to a stump (I can personally do down to 30mm). And the supervising teachers get really annoyed about this waste, but no matter how much the yell to their teams it doesn't seem to stop. This doesn't affect my life in anyway, but the waste still annoys me greatly. Well at least they get sent to recycling but still... most of the students in the school just don't give a single fuck.
But positive development has happened since they last time had a moment to yell to everyone, they stopped bending the rods before discarding them so they could be used. *This seems to be the only thing some people know how to do there, but I won't go in to that with much detail.
