3. Rules for Safe Operation
1. DO NOT USE IN DANGEROUS ENVIRONMENTS.
Do not use the solder pot in damp or wet locations or expose it to external environmental conditions,
particularly rain. Never use it in an explosive atmosphere. The heat from the heater can ignite fumes.
Be sure that the work area is well ventilated.
2. KEEP CHILDREN AND BYSTANDERS AWAY FROM THE SOLDER POT.
Do not let bystanders touch the solder pot. All bystanders should be kept a safe distance from the
work area.
3. USE FOR THE RIGHT JOB.
Do not use the solder pot for any purpose other than solder dipping work. For example: The solder
pot should never be used to warm water or other liquids.
4. WEAR PROPER APPAREL AND SAFETY GLASSES, MASK AND GLOVES.
Do not wear loose clothing (such as a necktie). Tie up long hair. Clothing or hair can burn on
contact with the molten solder or surrounding heated parts.
5. CONNECT TO THE SPECIFIED AC POWER SUPPLY.
The power voltage for this solder pot is indicated on the unit. Never plug the solder pot into any other
voltage.

6. DO NOT ABUSE THE POWER CORD AND INSPECT IT PERIODICALLY.
Never yank the power cord to disconnect it from the receptacle. Keep the power cord away from
heat, oil and sharp edges. If it is damaged, replace it.
7. FOR FACTORY USE ONLY
This unit has noise proof circuit for factory use. If used in a home environment it may affect
surrounding electrical appliances.
4. Operation Instructions
4.1 Set up
1. Hook the dross tray to the top-plate. It is possible to set
the dross tray on 3 sides of the unit so you can position it to
suit your needs.
2. Make sure the Power Switch is in the OFF position before inserting the power cord into the power cord
inlet and plugging the other end into a power outlet.
WARNING
To prevent fire, burns, and possible serious injury or damage:
⚫Keep the solder pot away from flammable substances and materials in the work area.
⚫Be sure to position the solder pot on a firm metal bench. The solder pot is heavy when filled
with solder and the solder bath and surrounding area becomes very hot.
⚫Unplug the solder pot power cord immediately if there is burnt smell or unusual heating occurs.
Do not use the solder pot again, and return it to the distributor you purchased it from.
⚫Do not leave the solder pot unattended when it is hot as the pot and surrounding area becomes
very hot.
⚫Do not touch any part of the unit other than the power switch or the control panel when it is
switched ON.

WARNING
Please observe the following in order to prevent solder splashing.
The splashed solder may badly burn you. Please be careful.
・Do not let the spatula get wet.
Steam is generated when a wet spatula contacts the molten solder. This may
cause solder to splash.
・Please use only the bundled spatula when you would like to
remove oxide.
Anything used in place of the spatula (Spoon,etc.) may cause solder to splash.
The spatula has unique features which cannot be substituted.
・Spatula surface must be clear and smooth.
Anything adhering to the spatula may cause solder to splash.
・If spatula has rust, please replace it with a new one.

3. Place the required amount of solder into the solder bath and turn the unit ON. Ideal solder level is
5mm below the rim of the bath.
4. Following the Control Panel setting procedure, input the temperature settings. This unit is set to
270 °C (518°F) prior to shipment.
5. When the settings are completed the Output Lamp (ot1) will light and temperature control begins. The
solder will melt in 7~8 minutes so put the solder into the pot little by little until it reaches the right level.
When the measured temperature (PV) and the set temperature (SP) are the same, the Output Lamp
(ot1) will flash and the temperature will be stable. The solder will be melted and work can begin
approximately 20 minutes after starting the temperature control. Before dipping, remove the oxidized
solder dross with the spatula and make sure the solder surface is clean.
6. Turn the unit OFF when not in use or when you are away from it.
4.2 Name of Parts and Control Panel Functions
The solder pot controller is a general-purpose model. The operator only sets temperature.
If you want to change the set up and parameter settings please refer the SDC15 operation manual included

and
the key is used to decrease
the value.
6.Registering the set value
After finishing the settings
please wait for 2 seconds
without pressing any buttons.

the operation display is shown.
Note 1: When nothing is input for over 2 seconds during the setting, the flashing value will be confirmed automatically and
operation display will be shown.
Note 2: It is not possible to set the values to more than the maximum temperature of 530 °C /986 °F.
Note 3: After setting is completed, close the protective cover. This will help minimize damage and keep the control panel clean.
Note 4: The unit operates at the old temperature while setting the new temperature.
5. Maintenance
⚫Keep the level of molten solder approximately 5mm below the rim of the solder bath.
⚫When using the solder pot for long periods, oxidized dross may collect around the walls of the solder
bath. This can cause poor heat transmission from the heater, overheating and insufficient heating of the
solder. Scrape the walls of the solder bath periodically with the spatula included with the unit to remove
oxidized dross.
WARNING
To prevent fire, burns, and possible serious injury, wear glasses, gloves and a mask before doing
maintenance.

6. Troubleshooting
Trouble: The solder does not melt.
a) The temperature setting display does not flash
Cause
Countermeasure
The Power Cord is unplugged at either end.
Plug it in.
The Power Switch is in the OFF position.
Set the power switch to the ON position
The Power Cord is damaged.
Replace the power cord.
The Fuse is blown.
Replace the fuse.
b) The temperature setting display flashes
Cause
Countermeasure
The set temperature is lower than the
temperature at which the solder melts.
Set the temperature to higher than that the solder
melting temperature.
The heater is damaged.
Replace the heater.
The alarm code display is shown.
Check the alarm code table in the SDC15
