2 INTRODUCTION
2.1 Oven use and purpose
The SDE-250 oven model is designed to dry and store stick welding electrodes at a desired
temperature to remove moisture. Desired temperature can be set, based on the recommendation from
the electrode manufacturer to achieve correct drying, ensuring the moisture content and for storage.
This oven should only be used for its recommended setting and usage.

Check the voltage, frequency information and check that there is no fault that will affect the
operation of the product.
4.1 Operation
WARNING!
When the oven is not in use, turn the power knob to “O” position and remove power cord plug
from electrical outlet.
• Connect oven power cord plug to a power outlet as recommended in the technical
information. Make sure the power outlet socket matches the oven power plug type.
• Load electrodes onto oven shelfs (trays). Do not place anything else (packaging
material, etc. as high temperature can burn it and cause fire inside the oven) besides
electrodes on these metal trays. Do not overfill trays and make sure the door can be
latched properly.
• Lock the door.
• On the oven control panel, to turn on the oven change power knob to “I” position.

• Once the power is turned on, depending upon the type of your oven i.e 1Φ one green
lamp will glow or 3Φ three green pilot lamps will glow. If the lamps or not glowing,
then check the power connection. Refer the below image.
• Setting the desired temperature
○ When the unit is turned on the controller display will show the current
temperature and set value.
○ Press and hold the SET button for 2 seconds to set a different
temperature. Use up and down keys to reach the desired set
temperature. Once the controller read out shows the desired
temperature, press SET key again.
○ The oven will now automatically heat up or cool down to the set
temperature. The oven will automatically turn off heating when the set
temperature is reached. The green lamp will also turn off.
• To remove electrodes from oven, when they have been dried at the desired
temperature.
○ Open and release the release valve on the top to avoid the hot smoke
exhaust when opening the front door.
○ Either turn off the oven completely or cautiously remove from the metal
trays and transfer to a portable oven (like PSE 5 or 10).
WARNING!
To achieve the maximum drying of electrode it is recommended to use FIFO (First In First Out)
principle. Must be cautious to not over-dry electrodes by leaving old electrodes inside oven
while only removing the newly added electrodes.
