2 INTRODUCTION
2.1 Oven use and purpose
The SDF-250 range of drying and storing ovens are large temperature-controlled cabinets for welding
powder flux in a typical industrial set up. They are designed for convenient top loading and bottom
removal of welding flux. The easy-to-use digital controller sets and regulates the temperature over a
wide range for baking, drying, and storing. Electric heaters embedded inside walls evenly heat the flux
without needing agitation or flux turning. Heavy insulation, rugged industrial design, external surfaces
electrostatic paint coating, heavy lockable castors make these ovens a great investment for long term
easy use.

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.
• Lock the door after the required amount of flux loaded (up to 250 kg).
• 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 use the welding powder, place a 5-gallon bucket underneath the oven spout. Pull
the lower arm to discharge powder into the bucket. When the bucket is full or enough
flux has been removed, push back the arm.
○ Open and release the release valve on the top to avoid the hot smoke
exhaust when opening the front door/
