    Default do I need a rod oven?

    Hey guys I have a heated shop,it's all ways right around 70 degrees, and all my 7018s sit on a work bench do u think I should have a rod oven?

    The only time you really need a rod oven is for low-hy code type work. If you are just welding your own stuff in your home shop then no.

    I would say ideally, yes. But a lot of stuff gets welded without one. What are you welding, for whom and how obsessive-compulsive are you? Have you encountered any of the conditions described below? Do I have one? No, but I'd like one cause I can be a little obsessive.---Meltedmetal

    From Lincoln website:
    Storing Low Hydrogen Stick Electrodes
    Low hydrogen stick electrodes must be dry to perform properly. Unopened Lincoln hermetically sealed containers provide excellent protection in good storage conditions. Opened cans should be stored in a cabinet at 250 to 300F (120 to 150C)

    Low hydrogen stick electrode coatings that have picked up moisture may result in hydrogen induced cracking, particularly in steels with a yield strength of 80,000 psi (550 MPa) and higher.

    Moisture resistant electrodes with an "R" suffix in their AWS classification have a high resistance to moisture pickup coating and, if properly stored, will be less susceptible to this problem, regardless of the yield strength of the steel being welded. Specific code requirements may indicate exposure limits different from these guidelines.

    All low hydrogen stick electrodes should be stored properly, even those with an "R" suffix. Standard EXX18 electrodes should be supplied to welders twice per shift. Moisture resistant types may be exposed for up to 9 hours.

    When containers are punctured or opened, low hydrogen electrodes may pick up moisture. Depending upon the amount of moisture, it will damage weld quality in the following ways:

    1. A greater amount of moisture in low hydrogen electrodes may cause porosity. Detection of this condition requires x-ray inspection or destructive testing. If the base metal or weld metal exceeds 80,000 psi (550 MPa) yield strength, this moisture may contribute to under-bead or weld cracking.

    2. A relatively high amount of moisture in low hydrogen electrodes causes visible external porosity in addition to internal porosity. It also may cause excessive slag fluidity, a rough weld surface, difficult slag removal, and cracking.

    3. Severe moisture pickup can cause weld cracks in addition to under-bead cracking, severe porosity, poor appearance and slag problems.

    Just put them in an old fridge with a lightbulb in it
