joint. Metcal tip car tridges detect the thermal load and instantly adjust the power in order to

deliver the right amount of heat precisely where it is needed. If the tip cools while transferring heat

car tridge and a hand-piece. The car tridge contains the solder tip, a heater and the wire coil.

When the temperature of the heater (a copper bar coated with a magnetized iron/nickel alloy)

reaches a cer tain level (its Curie Point), it stops absorbing energy and the temperature becomes

constant. Energy from the power supply feeds a steady current to the coil. This creates an electrical

field from which the heater absorbs energy, turns it into heat and transfers it to the iron/nickel

alloy. When soldering has drawn heat from the heater to the extent that the tip begins to cool, the

regulates the tip temperature to within ±1.1ºC of a set point regardless of thermal load and

without any need for adjustment.

Tr ouble-F r ee Tip Replacement

The heat-resistant pad supplied with the unit

allows you to easily inser t and remove the tip

car tridge. The simplicity of this process ensures

there is no loss of productivity, no need for

additional tools and no reason for two soldering

systems to be heating at the same time.

The Metcal Difference

In production environments where a single component can cost hundreds of dollars and rework and

repair can sometimes be more costly than the components involved, process control is vital. Metcal

improves product quality, increases productivity and reduces manufacturing costs with its patented

delivering the exact amount of power required for the task, consistent results are guaranteed and

versatility with no limits, no barriers and absolutely no compromise.

VARIABLE POWER HEATER

FIXED TEMPERATURE SOLDERING TIP

Switching to lead-free hand soldering does not necessarily mean that you will have to invest in new

equipment or adjust your existing process. As Smar tHeat’s variable power and fixed temperature

guarantee a repeatable tip temperature under a wide variety of thermal loads, the system can easily

adapt to meet the higher temperatures demanded by lead-free applications without any need for

modification.

No Calibration Required F o r Easy ISO 9000 Compliance

par t number. As the heater ’s alloy dictates the temperature, calibration is not required.

Indeed,

there are no dials, buttons or calibration tools, typical of other systems, with which you can adjust

Smar tHeat’s temperature. This avoids all risk of unauthorized operator inter vention. Throughout the

car tridge’s lifetime, temperature drif t is less than a few degrees. A letter to confirm Smar tHeat’s

self-calibration capacity is available on request.
