lazarus,
I live in a converted water mill, say no more.....
in my MIG welder I fitted a bulb holder (Bulkhead fitting type) it runs 24x7 with an 11watt
curleywhirley bulb fitted just under the mig wire roll...........
never had a problem since......I use the big heavy reels and got sick of them rusting up....
all other wedding consumables on a shelf above the house boiler....perfek....

How about bagging them up with those dessicant pouches ?
