TIMER KIT (K585-1)
The Timer Kit provides selectable 4-step trigger inter-
lock, spot and stitch functions, and manual adjustment
of burnback time. This kit installs easily using only a
screwdriver. It replaces the blank upper panel on Case
Front. It offers the following mode selections:
•
The Normal Welding mode provides welding
power only while gun trigger is pressed.
•
The 4-Step Trigger mode eliminates the need to
hold gun trigger while welding. It operates in 4
steps:
1.
Close trigger and establish welding arc.
2.
Release trigger and continue welding.
3.
Re-close trigger near end of weld.
4.
Release trigger again to stop welding.
•
The Spot Weld mode allows a single timed weld
cycle each time the gun trigger is held closed.
Duration is set with SPOT/STITCH ON TIME knob.
•
The Stitch Weld mode allows repeated timed weld
cycles while gun trigger is held closed. Weld on-
time is set with SPOT/STITCH ON TIME knob, and
weld off time is set with STITCH OFF TIME knob.
The BURNBACK TIME knob is used to manually set
arc power delay at the end of any above selected weld
mode to prevent wire sticking in the weld. With the
Timer Kit not installed, a preselected delay is automat-
ically set by the machine.
