PLATE
The Model 350 and the Model 350A are 350 Lbs. (159 kg) capacity electrode
stabilizing ovens used to maintain welding electrodes in their dry state or to dry 
electrode which have absorbed moisture. The Model 350 operated on single phase 
power with heat being supplied by a single element. The Model 350A connects to three 
phase power with heat being supplied by two elements. The ovens are normally located 
in a central storage area. They are complete with recessed controls, removable shelves, 
full insulation pilot light and a heating system incorporating low watt density elements. 
Temperature is thermostatically controlled. Nesting feet and sockets ensure safe, easy 
stacking of up to four ovens. 
 
Ensure adequate free space is provided around the ovens for safe loading and
unloading of the electrodes. Users should exercise caution when loading and unloading 
the oven. Certain parts of the oven and the electrodes may reach temperatures 
exceeding 550º F (288°C). All exposed body parts must be protected against accidental 
contact with hot materials. Safety glasses, gloves, overalls, and protective footwear 
must be worn when using the over. Hot electrodes must be unloaded into a suitable 
container capable of withstanding the heat and of containing the load safely. 
 
To minimize the risk of electrical shock the Model 350 and Model 350A
should not be exposed to rain or placed in a wet location. Liquids should not be placed 
in the oven. The oven should be connected to a suitable, fused power supply using a 
recognised connector. The oven must be properly earth grounded. Before performing 
ensure it cannot be restored. To minimise the risk of fire do not place food, beverages 
or other combustible items in the oven. 
USING THE OVEN 
 
The oven is loaded and unloaded via the front door. Avoid contact with hot
surfaces during this operating. The load should be distributing securely and evenly 
within the oven to ensure even heating. The shelves may be removed to accommodate 
larger loads if required.
