Damp looking Arc welding rods
locoR1 - 6/4/07 at 07:42 AM

As the title really I have a box of arc welding rods which I haven't used for a good few years they look damp!
I'm sure I've read about putting them in the oven to dry them out is this correct? has anybody tried it?

And the really important thing will they stink the house out, should I wait for SWIMBO to go out?

Thanks in advance Dave...........

quite a normal thing to do and they don't smell. I'd put them in at 100C for an hour or so but if you look on the pack I'd think there would be guide lines.

Yep, I've dried arc welding rods in an oven before.

100 Celsius for an hour or so will do it very well.

100degs is roughly 1/4 i.e 1 quater of a mark - HTH

Gas mark 5 was a good guess then!

A couple of points if i may.

Gas ovens are not ideal as gas gives off water as it burns.
(That's why your Sunday joint doesn't shrink as much in a gas oven.)

100C isn't enough. Most rod boxes suggest at least 200C, even up to 350C.
Murex Nicrex (stainless) are 350C for 2 hours.

Welders tip.
Lay a few rods across the palm of your hand and shake them so they rattle together.
They will make a dull noise.
Now do the same with DRY rods. They will make a higher pitch "ping" noise.

another tip
leave them on top of the boiler, and it keeps them at least dryish, if not properly dry
(at least they dont steam when you use them this way)

I keep mine in the airing cupboard behind the tank. Down at the yard we used to have a box with a permanently lit 60w bulb in it to keep them dry.

Absolutely.

As Dave & Pete says, better to keep them dry, than have to dry them.
