Product Description
Wiring
Check type and voltage on nameplate.
Type 200HT (120/240V AC only) single phase shipped at 1/240V wiring
Note: Type 200HT Series ovens are wired at the factory for 120 volts. For 240 volt
use, rewire heating element connections per the 240 volt wiring diagram.
Grounding
Type 200HT Series 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.
Amp Draw
Ovens operating on 120 AC voltage draw 12.5 amps. Those operating on 240 AC
voltage draw 6.3 amps.
Electrode Placement
DryRod® ovens have removable shelves to allow storage of more than one group
of electrodes. It is recommended to store different electrodes in separate ovens to
avoid contamination. Spread the electrodes evenly, allowing space over each shelf
for air circulation required to remove excess moisture. The maximum suggested
layer depth on any shelf is 5 inches.
Temperature Settings
Type 200HT Series oven temperature range is 100°F (38°C) to 660°F (350°C). The
thermostat dial (at front of oven) is calibrated at 120°F (50°C) to 660°F (350°C).
Required oven temperature setting is obtained by rotation of thermostat dial to line
up desired temperature with indicator light in the thermostat housing.
The indicator light illuminates only when voltage is being applied to the heating
elements.
Thermostat is accurate to +/-25°F (14°C) at the sensing bulb; however, temperature
may vary slightly at different areas in the oven chamber as this is a convection type
oven. For applications requiring higher temperature, an electrode rebaking oven is
required.
At the maximum setting, the actual temperature in portions of the oven near the
heating elements may reach approximately 700°F (371°C).
Temperatures over 660°F (350°C) are not recommended. They may cause oven
damage and/or unacceptably high exterior surface temperatures.
Venting
Before placing the oven into service, run the oven at 550°F (255°C) for two hours
with vent hole fully open. This will help to purge the oven of any contaminants.
(Smoke exiting from vent hole is common during burn-off of contaminants.)
For normal holding operation, set easily adjustable vent on the door about ¼ open.
For replacement vents, see Replacement Parts section in this manual.
Guide to Storage
Electrodes should be stored according to electrode supplier recommendations.
In the absence of storage information from your electrode manufacturer, please
reference Phoenix's Guide To Electrode and Flux Stabilization for approximate
temperatures, found at www.dryrod.com/guide.
CAUTION
• To provide continued protection against risk of electrical shock, power
cord must be connected to a properly grounded outlet.
• To avoid damage, never place oven in contact with welding current.
• Store in dry location. Unit not to be exposed to rain or moisture.

Troubleshooting
Oven Fails To Operate: No Heat
1. If the indicator light does not illuminate, check power supply.
2. Check plug at outer end of power cord and run continuity check on compete
power cord. If defective, replace cord assembly.
3. Check indicator light for continuity. See Repair Parts drawing for access
details. If defective, replace indicator light.
4. Check thermostat. If indicator light illuminates, power is being supplied
through thermostat to heating elements. Turn knob from low to high setting
and return. A definite "snap" should be heard at low temperature end, and
indicator light should turn off and on with each "snap" cycle. If "snap" is not
heard and indicator light fails to operate, replace entire thermostat.
5. If thermostat operates satisfactorily, check continuity of dual hairpin style
heating elements at bottom center of oven. Failure of one element will cause
very slow heating.
6. If thermostat operates satisfactorily, recalibrate thermostat. (See Checking
Thermostat Calibration section below.)
Oven Operates: Overheats, Low Heat,
Does Not Heat to Desired Temperature
1. Check power supply to confirm voltage is within acceptable range of 120 or
240 volts AC +/-10%.
2. Check that the variable thermostat is properly set to the desired temperature.
3. Check that enough time has been allowed for heat-up. A cold, fully loaded
oven may take up to four hours to fully heat and stabilize.
4. Check that the variable thermostat is securely mounted. A loosely mounted
thermostat will not properly sense the oven temperature.
Checking Thermostat Calibration
Each thermostat is adjusted at the factory and calibrated on precision instruments
to control temperatures accurately. Adjustment or re-calibration is not needed
unless the thermostat has been mishandled in transit or changed or abused while
in service.
To check calibration:
1. Use a high grade mercury thermometer to check temperature. For griddle
control, use a disc type thermocouple. Put a couple drops of oil on griddle
surface plate and place thermocouple disc flat into the oil.
2. Turn the dial of the thermostat to 300° mark.
3. Allow enough time for temperature to stabilize or until several temperature
readings are identical.
CAUTION
• When replacing heating elements, always replace both elements. Pairing
of one new element with an old element will cause rapid failure of old
element.

Warranty
Wiring
Eliminate expensive rework and protect welding profits!
This guide explains proper storage and oven holding temperatures:
• Recondition/rebake procedures for electrode coatings exposed to moisture are included.
• Remove electrodes from cardboard containers before placing in ovens.
• Electrode coatings should not be exposed to the re-baking temperature without first being reconditioned at a lower temperature. Failure to do so may result
in breakdown of electrode coatings. After re-baking, lower temperature to holding level until reissued.
