Welding on a soda blaster
« on: June 11, 2021, 12:22:34 AM »
I just bought a soda blaster. Its the local version of harbour freight, and you have to take the entire feed line out of the tank to fill it.
newer versions have a threaded bung on the side for filling.
I want to weld a bung on, but I cant fin any info about about welding and bicarbonate of soda. Do I just blow out all the powder and weld away?

If drying it is possible, I'd wash it out. Old grist mills would routinely blow up due to the dust in the air and stray sparks.

i'd wash it out first. soda dissolves in water pretty easily. and anyway, if you're going to drill it to weld a flange to it your going to have to wash it out anyway  :haw:
cheers, gil.
