I recently hinted that I’ve been working on a micro WK-inspired gasifier through a haze of depression.
Before starting to weld on the actual ammo-can and lower housing 5-gal steel bucket (which I was rightly anxious about, having never welded on anything that thin), I tried practicing on the scraps that I’d cut out of the bucket/ammo-can. Even on minimum settings on my little Hobart AutoArc 120v MIG welder, it was frequently burning-through almost instantly.
I have chunks of 3/16ths aluminium plate, or 1/4 inch steel plate, for heatsink backers, but it didn’t seem to make much difference.
Any suggestions/tips/tricks on how to actually weld up this thing so it’s air-tight without burn-through?
