Smartheat; Selecting Tip Cartridges; Changing Tip Cartridges - Metcal SP200 User Manual

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.
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.
