58 Revision: 28-Aug-06
Model 700
Vishay Micro-Measurements
FEATURES
• Separate visual and audible indicators monitor welder
status — Weld energy is continuously adjustable from 3 to
50 joules, making the Model 700 an excellent choice for
installing weldable strain gages and temperature sensors,
as well as small thermocouples and light-gauge metal.
• Supplied with a lightweight soldering pencil — A front-panel
control adjusts soldering tip temperature for a wide range of
soldering applications in the field or in the laboratory.
• “Low-battery” light to warn the user when the internal,
sealed lead-acid battery requires charging — A battery
charger is included to provide for full battery charge with no
danger of overcharging. Indicator lights monitor battery
charge rate.
• Convenient storage space for cables, battery charger and
instruction manual.
