Re: Patch panel welding advice needed
your burning thru the base metal because it is thin from rust
even if you get the metal to fill it will be very thin and rust out if the back side is exposed to water
a couple of choices:
cut out more metal until you get to thicker material
cover it with a layer of short strand filler like duraglass
backer material to suck up the heat
i'd get it to the second pic and cover it with duraglass
duraglass is waterproof vs regular filler will pass moisture thru
