this is one of the only times I saw him wear the mask; most of the time they just weld with their eyes closed. The dust from the flux burns, so there was a dropper with saline in it in the shop.
Before I left, I left about $1000 to buy new safety gear (helmets, aprons, gloves, safety glasses), but unfortunately somewhere between the check being delivered to the school and the shop, the money disappeared.
Bright arc lights, flying embers and no health & safety. Great for photos and not bad welds for first time welders!

This welding process, also known as welding a group of processes that uses heat released by a exothermic reaction to enable welding.
The exotherm of the reduction of a metal oxide is used as a source of energy for welding.
The oxides used are those that have a low heat of formation, while the reducing agents are those that have high heat formation.
The ends of the components to be soldered are placed
Inside a mold, specially constructed for the parts to be
welded.
In the case of welding cables or electrical connections, a Carbon-bonded graphite crucible; In the crucible that interconnects with the mold is placed the metal oxide (which will be reduced to pure element) and aluminum which is the reducing agent.
Steel produced in a refractory crucible, the
temperatures above 2000 ° C, is carried to the tops of
Rails, dissolving them and joining them homogeneously.
After 4 to 5 minutes the formers are removed and the surplus material is deburred. after the the weld is ground to reproduce the rail profile.
We managed to get the lid cut off a barrel and weld a old tire rim
onto the bottom of the drum. You can't get enough footage of all this.
