ASSEMBLY
The Metcal SP200 Soldering System consists of a power supply, workstand with wiping sponge,
and a solder handle that uses replaceable tip cartridges. (Tip cartridges are sold separately from
the system.)
The power supply features a green “Power On” indicator light, power cord, and a connecting port
for the solder handle cord. With the power “off”, attach the solder handle cord to the power
supply by inserting the cord connector into the power supply connecting port, and turn the nut
1/4 turn clockwise until it locks.
Insert a tip cartridge into the solder handle by aligning the flat end of the cartridge shaft with the
opening in the handle. Push the cartridge all the way until it seats. You should feel a slight “click”
as it locks into place.
Wet the sponge with deionized water until it is moist but not soaked. Then place it in the
workstand tray.
Plug the power cord into a grounded wall socket of the appropriately rated input line voltage. To
turn the unit on, push the switch on the top of the power supply. The green indicator light should
light up. If it does not, see the “Troubleshooting Guide” in this manual.
CAUTION: To provide continued protection against the risk of electric shock, connect only to
properly grounded outlets.

METCAL SMARTHEAT - NO DIALS TO SET
Each tip cartridge contains a self-regulating heater that senses and maintains a set idle
temperature. The temperature is determined by the inherent metallurgical properties of the
heater; no external adjustment or equipment is required. The power delivered to the tip
automatically varies in direct response to the thermal load. This eliminates spikes and transients
associated with electrically switched elements found in conventional soldering irons.
SELECTING TIP CARTRIDGES
Metcal tip cartridges come in a variety of tip geometries and two standard temperature ranges
(600 Series and 700 Series). Some tips are available in low temperature 500 Series. These tips
cover a broad range of tasks from delicate precision work to heavy ground plane soldering.
1. Pick a tip that maximizes contact area between the tip and solder joint. Maximizing contact
area gives the most efficient heat transfer, producing high quality solder joints quickly.
2. Pick a tip that allows good access to the solder joint. Shorter tip lengths allow more precise
control. Longer or angled tips may be needed for soldering densely populated boards.
3. Pick the lowest temperature tip cartridge that will accomplish the task. This minimizes the
potential for thermal damage. Start with a 600 Series cartridge and switch to a 700 Series only
if you need more heat. The temperature series is marked on the shaft.
CHANGING TIP CARTRIDGES
1. Push the Power Switch “Off.”
2. Pull out the cartridge using the CP1 Cartridge Pad. DO
NOT USE METAL TOOLS (SUCH AS PLIERS) TO
REMOVE TIP CARTRIDGES, AS THIS CAN DAMAGE
THE HEATER.
CAUTION: THE TIP CARTRIDGE MAY BE HOT!
3. Push a new cartridge into the solder handle with the
CP1 Cartridge Pad (as shown on previous page)
4. Push the Power Switch “On.” The new tip cartridge will heat up to temperature in less than
20 seconds.

EXTENDING TIP LIFE
1. Each day, remove, inspect, and clean the cartridge shaft and
handle using denatured alcohol and a clean cloth. Stubborn
flux deposits on the shaft can be removed using a brass
brush. Do not use a brass brush on the tip itself as it will
damage the plating and shorten tip life.
2. Use the right tip. The plating on fine precision tips is less
durable than the plating on blunter tips. Lower temperatures
decrease tip oxidation.
3. Do not use the tip as a prying tool. Bending the tip can cause
the plating to crack, shortening tip life.
4. Use the minimum activation flux necessary to do the job.
Higher activation flux is more corrosive to the tip plating.
5. When making a solder connection, apply fresh solder to the
members being joined, not to the hot soldering tip.
6. Don’t apply pressure to the tip. More pressure does not equal
more heat. To improve heat transfer, use solder to form a
thermal bridge between the tip and the solder joint.
7. Clean tips on a clean, wet sponge — not on a rag or dirty dry sponge.
8. After you turn on the system, and each time you return the tip to the
holder, apply rosin core solder to the tinned surfaces of the tip. The
solder protects the tip from oxidation and prolongs the life of the tip.
9. Switch the system off when not in use.
DETINNED TIP CARTRIDGES
A detinned tip is one not wetted with solder. This exposes the plating to oxidation and degrades
the heat transfer efficiency of the tip. Detinning is caused by:
a. Failure to keep the tip covered with fresh solder during idling periods.
b. High tip temperatures.
c. Lack of sufficient flux in soldering operations.
d. Wiping the tip on dirty or dry sponges and rags. (Always use a clean, wet, industrial grade,
sulfur-free sponge.)
e. Impurities in the solder, iron plating, or on the surfaces to be soldered.
To restore a detinned tip cartridge:
1. Remove the tip cartridge from the solder handle and allow the tip to cool down.
2. Remove scale and oxides from the tinned area of the tip with 80-grit abrasive polyurethane
foam stock (Plato AB-3 Polishing Bar or Multicore Tip Tinner/Cleaner or equivalent) or a 100-
grit emery cloth.
3. Wrap rosin core solder (0.031” diameter or larger) around the newly exposed iron surface,
insert the tip cartridge into the handle, and turn on the system.
Note: Detinned tips are preventable with proper daily care!

TROUBLESHOOTING GUIDE: TIP CARTRIDGE WON’T HEAT
1. Be sure the tip cartridge is pushed all the way into the handle.
2. Check that the handle cord connector is tightened securely to the power supply
output connector.
3. Check the power supply “On/Off” indicator light. If it is not lit, make sure the 3-wire
power supply cord is properly connected into the wall outlet and the power supply.
4. If the cartridge still won’t heat, try a different cartridge. If the new cartridge heats,
discard or return (if in warranty) the bad cartridge.
If the above steps do not result in proper performance, call Metcal Customer Care.
