I have a half box of 6013 electrodes which got lost in the shed for a
while. Normally I keep electrodes in the house, but as I say, these got
lost so they've spent about 5 years in an unheated shed. I wouldn't
bother with them except that they're 1/16" electrodes, which are handy
for welding 2 mm plate, and the welding shop which used to sell them
locally closed down. They seem to be showing a bit of a powdery white
deposit on the surface of the flux, perhaps something which the damp has
Can these electrodes be dried successfully, or should I get some new
ones? Suggestions would be appreciated.
The white stuff is silicate (binder) that has leached out over time. It
isn't anything to worry about, and can even be wiped off with a slightly
damp rag if needed. Unless rust is present, no need to "dry" the 6013.
Chris, put the electrodes on top of the refrigerator for a week... This
is usually a warm, dry place with heat from the exchanger flowing up
the back of the fridge...
Or, 4 hours in the electric oven set at 250 degrees farenheit...
Or in a cardboard box with a 25 watt electric light bulb - use common
sense so you don't get a fire...
Or, fall is coming and you will be using the heater in the car... If
you are going someplace put them on the floor near the heater outlet...
Or in the house somewhere on the furnace...
On top of the water heater...
