First you can t open the door from inside many old refrigerators so any curious kid prowling around the job site can climb in and suffocate.
Drying welding rods in kitchen oven.
Different rods sometimes need different temperatures for example lo hy 7018 rods should be baked at around 250 for best results.
Another myth is that you can put a light bulb in an old refrigerator and store your welding electrodes in it.
An oven that s too hot will remove the flux coating and an oven that s not hot enough won t adequately dry the rods.
For drying remove the electrodes from the container and spread them out in the furnace because each stick electrode must reach the drying temperature.
Low hydrogen electrodes like the commonly used e7018 must be dry to perform adequately once the original package has been opened they must be stored in an electrode oven at 250f 300f.
Filthy rich will teach you how to save your welding electrodes if they have collected moisture after not being stored properly.
The rods should be placed in the rod oven at a temperature of 180 220 degrees fahrenheit for one to two hours and then they can dry properly at their normal temperature for one hour.
If someone s told you that you can dry wet welding rods in your oven or put rods in a freezer if they are old you ve heard two welding myths.
I don t see why you couldn t use a home oven for this although you do raise a good point about.
Ideally you want your welding rod ovens to be between 250 350f for optimal performance.
Proper storage methods or re drying procedures must be applied.
Preheating rods dries them and minimizes cracking and stress risers during welding.
