General Information

Introduction

Thank you for purchasing the PACE SODRTEK

model ST 125 Analog Desoldering System. This manual will provide you with the information necessary to properly set up, operate and maintain the ST 125.

The ST 125 system is available in either 115 VAC or 230 VAC versions, which incorporates a highly responsive SensaTemp (closed loop) control system providing up to 80 Watts of total power to a single output channel. The 230 VAC version system bears the CE Conformity Marking, which assures the user that it conforms to EMC 89/336/EEC.

The 115 VAC version systems conform to FCC Emission Control Standard, Title 47, Subpart B, Class A. This standard is designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
