All Metcal soldering, desoldering, and rework systems are designed and tested to meet or exceed all applicable ESD and EOS standards which apply to soldering products.
Metcal soldering systems offer superior EOS/ESD protection. Because our soldering systems deliver continuous current, they cannot generate switching transients.
Typical values for tip-to-ground resistance and tip potential are 0.8 ohms and 1.0mV RMS, well within the commercial/international specifications.
Metcal also offers extra protection against potential ground faults in its CV, MX, and MFR Series Soldering Systems with an Auto-Off feature. This feature senses the DC continuity (resistance) of the output cable and handle assembly through the cartridge. If the resistance of the output circuit exceeds a preset reference level, the system is turned off. This is fail-safe protection against any ground loss.
On the Metcal CV, MX, and MFR Series soldering systems, a ground fault monitor is built into the power supply to continuously monitor the AC supply (mains) ground circuit. In the event of a mains ground failure or if the mains ground should go out of specification, the system is immediately switched off and the system cannot be re-powered until the mains ground is restored.
