Power Switch Detail
When you first open the Pro tool's case, a translucent cap protects the electrical contacts at the front end of the tool.
Remove the protective cap and insert one of the tips by pushing it into the tool.
1. Slide the ON/OFF switch on top of the tool to the appropriate power setting (I for low power or II for high power). The
white light illuminates, and although the tip is still cool, your tool is now ready to solder.
2. To heat the tip, gently place it against the electrically-conductive work piece so that both tip electrodes make solid
contact with the work piece; then add solder. If the tip is placed correctly, the red light illuminates and the tip will create
heat almost instantly, allowing for clean solder flow and the formation of a smooth joint. A slight spark may occur at the
tip during soldering.
3. When the joint is complete, remove the tip from the work piece. The tip should cool off to touch-safe temperatures
within a few seconds to a few minutes, depending on the length of your soldering process.
Correct Contact
Work piece makes contact
with both halves of tip.
CAUTION:
DO NOT PRESS HARD. Excessive pressure does not improve performance and may break the tip. If the tool is not supplying
the required heat, the tip electrodes are not both making contact with electrically-conductive material. Reposition the tool for better
contact until the red light turns on.

troubleshooting, help and frequently asked questions.
Incorrect Contact
Work piece makes contact
with only one half of tip.
Meaning
The tool is shut off.
The tool is soldering and the tip is hot.
Error. Turn power off and check tool*.
Below are a few operational tips intended to improve your soldering technique with the Pro Soldering Tool:
Low Power
• This tool is intended for short bursts of heat. Do not dwell on a single soldering joint for a long duration.
• The Low Power setting (I) is best for smaller projects (tinning 20-24 gauge wires, or equivalent). The High Power setting
Off
(II) is best for larger projects (tinning 12-18 gauge wires, or equivalent).
• If you are having trouble establishing electrical contact between the Split-Tip™ electrodes and the work piece, tilt the tip
High Power
so that it touches the work piece at an angle. The red light will then turn on when the tip makes correct contact with the
work piece. A few minutes of practice will go a long way to ensure that you enjoy your tool. Remember: light-handed
operation will prolong the life of your tip and create better joints.
• Users more experienced with the soldering process will recognize that the Split-Tip™ eliminates the need for wetting and
cleaning the tip. The tips can also be used for desoldering with wick.
• When soldering electronic components with small pin-outs, do not bridge two or more different pins with the opposite
White pen-light
halves of the Split-Tip™. Doing so will cause a current discharge and may damage the part.
• Turn off the tool when not in use. Extended use of the white light will diminish battery life.
• A new set of batteries will perform approximately 700 joints under normal conditions. We recommend that you replace the
batteries often to maintain high performance from your tool.
Red "in use" light
• For best results use solder approximately 1 mm (0.040") in diameter.
Follow these safety precautions to reduce the risk of personal injury or property damage from fumes, burns, or fire.
WARNING
• Use with proper ventilation, use caution, common sense, and become educated about the soldering process. This
product, when used for soldering and similar applications, produces chemicals known to the State of California to cause
cancer and birth defects (or other reproductive harm) (CA Health and Safety Code 25249.5 et seq.) Flux fumes from
soldering and de-soldering can be harmful, especially when using lead-based solder.
To reduce the risk of fire or explosion:
• Do not operate near flammable or explosive materials. This tool may create a spark at the tip while soldering, which
could ignite flammable fumes, liquid or other materials.
To reduce the risk of personal injury or property damage from burns or fire:
• Do not touch the tip during active operation (indicated by the red light). Make sure that the tip is cool before touching or
replacing the cap. Allow sufficient time for the tip to cool before touching it. Under most circumstances, the tip will cool
to the touch very quickly. However, after prolonged use—such as after applying solder to several joints or applying
solder to a work piece for a long time—the tip may take longer to cool down.
• Be sure the Split-Tip
of metallic debris is lodged in the gap between the Split-Tip electrodes. If debris is lodged in the Split-Tip
unit off and use a thin, non-conductive material such as a toothpick to wedge the debris out of the Split-Tip
• Turn the soldering tool OFF when not in use. The tool may inadvertently create heat if it is left in the ON position and
conductive material becomes lodged between the Split-Tip electrodes.
• Keep out of reach of children.
CAUTION
To avoid damage to your soldering tool:
• Do not apply unnecessary pressure to the Split-Tip
break the tip. Light-handed operation will prolong the life of your tip.
• Do not store tool in high-temperature environments as this can damage the batteries and electrical parts.
• Do not attempt to repair the soldering tool. This could damage the tool and will invalidate the warranty.
