Models 10A20 and 10B20 portable Electrode Stabilizing Ovens are capable of maintaining electrodes in a dry
state once removed from their storage site. They are intended for use by the welder while at the site and not
for permanent storage of rods. With normal duty cycle usage (opening & closing of the oven to access the
electrodes) the Model 10A20 maintains an average internal temperature of approximately 275°F (135°C). If
left energized and unopened for an extended period of time, the Model 10A20 will reach higher internal
temperatures. The temperature of Model 10B20 oven is regulated by a thermostat to maintain constant
internal temperature, whether rods are regularly removed or not. The temperature control on the Model
10B20 is recessed for protection from physical damage. The Model 10A20 and 10B20 incorporate a pilot light
to indicate oven operation.
Care must be taken when loading and unloading electrodes from the oven. The electrodes and the rod lifter
handle may be hot and it is essential that any user of this equipment wear protective gloves and protective
eye wear.
To minimize the risk of electrical shock the Model 10A20 and 10B20 ovens should not be exposed to rain or
placed in water. Do not touch an oven that has been exposed to rain or fallen into water until the power cord
has been disconnected from the power supply. Do not use the oven if the power cord or plug is damaged.
Wrap the power cord around the brackets on the side of the oven when not in use to prevent damage to the
cord and plug. This equipment must be connected to a suitable power supply using a recognized connector
or fused switch. This equipment must be properly earth grounded. Before any attempt is made to remove the
bottom cover, the power supply must be isolated and precautions taken to ensure that it cannot be restored
while the unit is being worked on.
USING THE OVEN
The oven is loaded and unloaded from the top using the rod lifter. The rod lifter handle may be hot
and gloves should be worn to prevent burns. The rod lifter should be pulled up and secured in the
raised position using one of the two rests on the rod lifter. Electrodes may then be loaded or
unloaded. When finished, the rod lifter should immediately be returned to the closed position.
To adjust the temperature setting of the Model 10B20 oven place the oven on its side on a bench or
other raised surface. Rotate the thermostat shaft using a slot screw driver, clockwise to increase the
temperature.
