FILLING/REFILLING
1. Make sure the gas control ring is in "OFF" position.
2. Hold refill container above unit and press the container nozzle into gas refiller valve. (Fig 1)
3. Complete fill takes about 10 seconds: then allow a few minutes for gas to stabilize.
LIGHTING
1. Push up, then turn the gas control ring clockwise to release a small amount of gas
(hissing sound) through the burner. (Fig 2)
2. Use the lighter in cap (or lighter) to ignite at the tip exhaust ports (or torch). (Fig 3 & 4)
ADJUSTMENT
1. Temperature can be controlled by the gas control ring between low and high.
… Adjust the torch of flame to approx. 1/2 inch (12mm) length. Don't make the flame too
long, it will only waste gas.
… Adjust the temperature for soldering (Also hot knife & polyfoam cutter) to approx 1/2
Position, do not set the temperature too high on work that will cause the tip's catalyst
to burn.
TURNING OFF
1. When finished turn the gas control ring counter clockwise to "Off Lock" position and
allow the tip (Torch) to cool before changing tips or storing.
CLEANING ORIFICE
For peak performance cleaning the orifice periodically is recommended.
1. Turn off gas control. Make sure unit is cool.
CHANGING TIP
1. Make sure the solder head and burner are not hot.
2. Remove the burner head from the connector and then screw in the solder head with the
connector and then screw in (snug fit) any small tip (See Optional Accessories) you
need for your job. (Fig 5)
3. Remove the solder head from the connector, and screw in the burner head, with
connector your tool can now be used as a torch. (Fig 6)
TIPS ON USING YOUR SOLDERING IRON
1. Select the proper solder for your application. Most solders sold today have the flux
inside their cores. When making electric or electronic connections always use rosin core
solder. For mechanical joining where the surfaces can be washed after soldering acid core
solder can be used. Common nonplumbing solder is an alloy of tin and lead. A “60-40”
solder is 60% tin and 40% lead. General purpose solders range from 40-60 to 60-40.
63-37 solder has the lowest melting temperature and highest strength. The diameter of
the solder wire should generally match the size of the components to be joined.
2. Be sure the surfaces to be joined are clean. Remove any oil or grease. Surfaces can be
thoroughly cleaned by using abrasives such as emery cloth, steel wool or by scraping
or filing. The flux in the solder will remove the oxide layers which could prevent good
bonding.
NOTE: New units are shipped untinned. Remove plating at end of tip before tinning.
3. BE SURE THE TIP OF THE SOLDERING IRON IS CLEAN AND WELL TINNED (COATED
WITH SOLDER). The solder on the tip of the iron will melt rapidly and create a conductive
path for the heat to reach the workpiece. A small additional amount of solder may be
added to the tip while it is in contact with the workpiece to ensure good heat conduction.
4. If possible connect the workpieces mechanically, or position them as rigidly as possible.
5. Allow the soldering iron to heat sufficiently: 1 minute minimum to about 3 minutes for
optimum operating temperature.
6. Apply the heated tip of the soldering iron directly to the work. Heat the work surfaces
sufficiently for the solder to melt on them. Apply the solder to the work surface directly.
Do not just melt the solder on the tip of the iron allowing it to fall onto the work. This
will cause poor bonding between the solder and the surfaces to be joined. Remove the
iron quickly after the solder flows on the work surfaces.
TROUBLESHOOTING
PROBLEM PROBABLE CAUSE CORRECTIONS
Does not ignite Low/No gas Refill with butane gas
Gas pressure Rotate the regulator
too high or low to lower or higher position
Excessive gas flow Setting too high Adjust the regulator to "OFF" position,
or Catalyst pulsing gradually reduce the gas volume
red to black
Tip does not heat up
Used up catalyst Replace with new tip
SAFETY STAND
Put unit on stand when not in use.
CLEANING
Use only the mild soap and a damp cloth to clean the housings of the tool. Many house-
hold cleaners contain chemicals which could seriously damage the plastic. Also do not use
gasoline, turpentine, lacquer or paint thinner, dry cleaning fluids or similar products. Never
let any liquid get inside the tool; never immerse any part of the tool into a liquid.
IMPORTANT
To assure product SAFETY and RELIABILITY, repairs, maintenance, and adjustments
should be performed by Service Centers or other qualified organizations. This tool contains
no customer serviceable components.
Warnings:
1.1 Soldering Iron contains flammable gas (Butane) under pressure—use with care.
1.2 Do NOT expose to heat above +50°C (+120°F) and avoid prolonged exposure to the sun.
1.3 Do NOT puncture or incinerate.
1.4 Excessive gas flow, flaming or catalyst pulsing red may occur when the regulator is
incorrectly adjusted, i.e., set high. It is essential, therefore, to keep iron away from
face and body when igniting.
1.5 Do NOT refill, ignite or use near flame, heater, furnace or combustible materials.
1.6 KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.
1.7 KEEP CHILDREN AWAY. All visitors should be kept away from work area.
1.8 STORE IDLE TOOLS. When not in use, tools should be stored in dry, and high or
locked-up places out of reach of children.
1.9 USE SAFETY GLASSES.
1.10 DON’T OVERREACH. Keep proper footing and balance at all times.
1.11 STAY ALERT. Watch what you are doing. Use common sense. Do not operate tool
when you are tired.
1.12 DO NOT TOUCH THE HEATED TIP OR BARREL OF THE SOLDERING IRON.
1.13 DO NOT leave operating or hot soldering iron unattended.
1.14 ALWAYS BE SURE THE SOLDERING IRON IS COOL BEFORE STORING IT.
1.15 DO NOT REPLACE CAP WITHOUT
SWITCHING OFF AND ENSURING TIP HAS COOLED. Do ensure flames are
extinguished before putting down. If flame does not self extinguish within 30 seconds
a new tip is required.
1.16 Do USE Iron in a ventilated area.
1.17 Do NOT attempt to readjust or repair, this product is not user serviceable.
WARNING: This product, when used for soldering and similar applications, produces
