why bother with 7018 if yuu cannot keep in oven.

storeman · Sep 9, 2014

Our welding school uses only 7018 and 2 open cans sit in a file storage cabinet. Welding certs are done from the same stock.

My grandpa was a pipeline welder, and used an old non working refrigerator with a 100 watt light bulb in it. It was always so hot in that fridge when you opened it. It made a great rod oven

Add a 1/4" fitting with a schrader valve to your rod holders and use an a/c vacuum pump to remove moisture. :laugh::laugh::laugh:

How would a ice chest with a hundred watt bulb work? Or would it get too hot for the plastic?

Too hot.

Someone who ran his own welding supply company specializing in welding rod told me that most modern low hydrogen rod produced today has a sealer in the flux that reduces moisture pickup. He told me that technically the rods didn't need to be baked. To conform to code however they must be stored in a proper heated oven.
With all the rod I have used that was stored in in questionable circumstances I have never had failures from hydrogen entrapment. Of course I am a belt and suspenders kind of guy and use preheat religiously on heavier material.
I have done a crude hydrogen test using glycerin. I was doing this for welding students in a class so it was a crude experiment. I easily could get hydrogen bubbles showing if I soaked a cellulose rod in water before welding the sample. I had absolutely no luck with getting any visible bubbles with low hydrogen rods so I soaked one and still didn't get bubbles. It leads me to think that that guy might have been telling the truth.

There are moisture resistant 7018 electrodes.Lincoln for example has Jet 7018 MR and Excalibur 7018 MR.

I wish I had a dollar for every pound of 7018 I've run in the pouring down rain.

X2!! Been there, done that, CEP.

Bake or Not to Bake ?

Remember Supposed Too and Does are two different things.

I seen some 7018 MR's today. Box said "magnesium" so I figured it had something to do with that. I guess the "MR" means "moisture resistant" then?

I saw some too, on the floorboards of my truck! 20 more lbs of 5/32 for an excavator thumb install. Yep, MR is Moisture Resistant.

I think some of the newer members here are so afraid of screwin' up they're not getting anything done. Get outside that box and burn some 7018 even w/o an oven!!

That's what I did. I tried them years ago, but had bad luck with them. Bad box maybe. Got some more last week and am loving the 7018

I have my rods in an old metal ice chest with one of these new flourescent 60w bulbs, stays warm, am I doing any good you think?

CEP · Sep 9, 2014

I used an old smoker than was given to me, before I found a rod oven at a good price.

That's a great idea! I have a cabinet about that size that is designed to hang on the wall. Once I find it a home inside my garage I'll have to fit it with a bulb an start storing my rods in it. How much heat do you think the standard plastic rod containers can handle?

CEP · Sep 9, 2014

I don't know. But don't go with a heat lamp like is shown in the picture

! Just use a regular light bulb. It doesn't take much to heat up that small of cubic inches. And it's not like the door is opened every few minutes either.

Yeah, I thought about that. My uncle has a cabinet for his electrodes with a 100 watt bulb and it stays plenty hot.

3/32 7018 sitting in a bucket for the last 2 years run with a maxstar 150 120v

sent while goofing off at work

Welding rods are probably a better desiccant than many desiccants. Silica gel is not so great. Calcium chloride is. Non-dairy coffee creamer is supposedly good.

why bother with 7018 if yuu cannot keep in oven.
