That would be cool. A carbide lamp would be nice too, since we already have calcium carbide lumps:
Maybe we should also have some way to produce oxyacetylene, too? It seems the hardest part of that is getting the calcium carbide. Afterwards, any schmuck can make acetylene gas*, and if you collected it and mixed it with the gas from an oxy tank, it should be good enough to weld with.
* with the caveat that if he’s REALLY a schmuck, he may blow himself up – the reaction is exothermic so you have to be careful not to let it run too fast and get too hot, otherwise it might ignite the acetylene it’s producing and explode!
