Weld-CHRON Arc Weld Timer
Operation Manual
Weld-CHRON Arc Weld Timer 1

WELDING MODE
The Weld-CHRON will enter welding mode when the welding current sensed
by the transducer exceeds the fixed trigger level, typically 15-20 amps.
During welding, the Weld-CHRON displays the duration of the current weld in
seconds. The format of the display is M:SS. The arc symbol in the
upper left corner is illuminated during a welding operation.
At the completion of the weld, the display will pause in this state for a few
seconds, and then begin to alternate through the cumulative information
displays.

Weld-CHRON Arc Weld Timer 2

During non-welding (idle), the Weld-CHRON cycles between three screens:
▪Total number of weld strikes since last reset
▪Duration of last weld
▪Total accumulated arc time since last reset.

RESET
The Weld-CHRON Arc Weld Timer is reset using a key-switch. When reset, all accumulated
totals are set to zero.
To reset, insert key-switch
and turn it to 90-degrees to
the right (CW) for 15
seconds.
The expected battery life is approximately 2-years. As the battery voltage approaches the
critical level, the battery symbol appears.
To replace the battery, loosen the four (4) screws securing the top cover. The screws have
retainers, so they should not be completely removed. Lift off the top cover and the batteries
will be accessible.
Standard replacement cells are 4X-1.5volt AA Alkaline cells (ANSI-15A / IEC-LR6 or
equivalent). As an alternative, enhanced service life may be attained using a lithium based
cell such as the Energizer Ultimate Lithium Type L91 (ANSI 15-LF), however the user must
take the necessary precautions appropriate for the use of lithium cells.
