THERMOCOUPLE AND FINE WIRE
WELDER
TL-WELD
Operating Instructions
The TL-WELD welder is designed for sensor manufacturers
to produce commercial grade thermocouple junctions, and by
users of large numbers of exposed junction thermocouples
such as test and development laboratories where multipoint
temperature sensing of test pieces is required.
No special skills are required and most people will be capa-
ble of producing quality work with minimal practice. A sat-
isfactory thermocouple junction is produced without using
argon, but where argon is available a momentary purge is
automatically triggered immediately prior to the weld to
give optimum weld integrity.
Safety Note
1. Always protect the eyes with a suita-
ble
filter during welding – never view
the
weld discharge with the naked eye.
2. Avoid touching the rear of the welder during operation
as the power switch heat sink may run hot. This is a
normal operating condition.
3. Do not allow the hand to directly contact the welding
electrode during operation.
