OVEN TYPE DESCRIPTION
Wiring
Check type and voltage on nameplate.
Types 50B 120/240V AC only models utilize a tamperproof
sealed thermostat, providing a 300°F average stabilized load
temperature.
Type 50C/120V AC/CD (Non-Thermostat model), utilizes
constant heat input, providing a 300°F average stabilized
load temperature.
Note: All current 50B ovens rated at 120 volts have a Model
1 designation, 240 volt ovens have Model 2 designation.
Grounding
1. The 120 volt ovens have a three blade plug cap with
grounding prong (NEMA 5-15P) attached to a 10 foot power
supply cord. When used with a grounded receptacle, these
ovens meet all local electrical code requirements and are
U.L. Listed.
2. The 240 volt ovens have a 10 foot power supply cord.
When used with a grounding plug cap and a grounded
receptacle, these ovens meet all local code requirements.
Electrode Holding
1. Open lid of oven and allow approximately 20 minutes
warm-up time to drive out any retained moisture.
2. Place only dry electrodes within oven. Keep lid closed but
unlatched while plugged into power receptacle.
Electrode Storage
These ovens are not to be used for rebaking or recondition-
ing contaminated electrodes. They are designed to accept
electrodes in 100% useable condition and to maintain that
condition until consumed at the job site. For optimum stabi-
lization, oven should be hot when loaded and kept "on line"
as long as electrodes are being stored.
Type 50 series ovens are not airtight and electrodes stored
within will start absorbing ambient moisture as soon as the
oven cools. We recommend removal of electrodes at shift
end and storage of same consumables in suitable larger
holding ovens until reissued.
Guide to Storage
In the absence of detailed storage information from your
electrode manufacturer, the "Revised Guide To Electrode
Storage" (available from Phoenix International, Inc.) may be
used as an indication of approximate temperatures for use
of the oven. For Specific information involving critical oper-
ations be sure to contact your electrode manufacturer for
complete information.
