Introduction
The WS500 welding control offers the reliability that ensues from simplicity. The WS500 is a
compact, robust unit providing basic control for resistance welding. The membrane front panel
provides a neat, water resistant finish and incorporates four push buttons and a display for
programming purposes. Programming is quick and simple, as is operation of the control.
Installation is also easy. The WS500 has four mounting studs and sixteen connections on a plug-
in connector block.
The principle features of the WS500 are:
• Operates from 24 volt DC supply
• 50 Hz or 60 Hz operation
• 4 inputs and 4 outputs plus weld on/off
• 1 to 8 programmes, depending on mode of operation
• Configurable for: Single spot
Repeat spot
Half cycle
Roll spot
Seam
• Two weld intervals, upslope and pulsation
• Retract/High lift option
• Counter with configurable lock-out
• Cross-interlock facility (2 options)
• Built-in test routines

Configuring the WS500
The WS500 has various configurations to tailor it for specific applications.
• Press
F
until it the display reads WS500 V1.04
• Hold down and then press
F
. The display will read CONFIGURE.
• Press The display will read, for example, CONFIG TYPE 00 This is
the first item in the list of configuration parameters.
a) If you wish to change the parameter setting (in this case 00) use the
+
or
-
keys to make the required selection. Press to enter the value. If you do not wish to
change this parameter move directly to b).
b) Press to move to the next item in the configuration file.
• Repeat steps a) and b) until the configuration is complete, then press
F
.
Configuration Parameters
The items in the list of configuration parameters is shown below.

Interlock On or Off
Heat range Low or High
X-lock type External or Ring
Config Type
The WS500 has 13 modes of operation, numbered as “Types” 0 to 12. Each Type offers different
features, different numbers of weld programmes and may use the input and output connections in
different ways. The following table gives a brief description of what each Type does, and shows
the number of weld programmes available for that option.
The table should be used in conjunction with the tables of Input and Output Allocations which
show how the inputs and outputs are used for each configuration Type.
Config Type WS500 Operation No. of weld

00 Spot/repeat
Simple spot welding with single or repeated weld sequences
and no other functions.
8
01 Spot/repeat with cross interlock
Spot welding with single or repeated weld sequences giving
an interlock output to prevent other timers welding at the
same time.

02 Spot/repeat with retract
Spot welding with single or repeated weld sequences with an
input and output for controlling the “open” and “working”
positions of the welding gun.
4
03 Spot/repeat with counter
Spot welding with single or repeated weld sequences with a
counter that gives an output when the programmed number
of welds has been reached.
4
04 Spot/repeat with cross interlock and retract
Spot welding with single or repeated weld sequences giving
an interlock output to prevent other timers welding at the
same time, and an input and output for controlling the “open”
and “working” positions of the welding gun.
2
05 Spot/repeat with counter and retract
Spot welding with single or repeated weld sequences with a
counter that gives an output when the programmed number
of welds has been reached and has an input and output for
controlling the “open” and “working” positions of the welding
gun.
2
06 Spot/repeat with counter and cross interlock
Spot welding with single or repeated weld sequences with a
counter that gives an output when the programmed number
of welds has been reached and with an interlock output to
prevent other timers welding at the same time.
2
07 Spot/repeat with counter, cross interlock and retract
Spot welding with single or repeated weld sequences with a
counter that gives an output when the programmed number
of welds has been reached, also an interlock output to
prevent other timers welding at the same time and with an
input and output for controlling the “open” and “working”
positions of the welding gun.

08 Half cycle
Spot welding using only a half cycle of weld time. 8
09 Half cycle with cross interlock
Spot welding using only a half cycle of weld time and giving
an interlock output to prevent other timers welding at the
same time.

10 Half cycle with counter
Spot welding using only a half cycle of weld time also with a
counter that gives an output when the programmed number
of welds has been reached..

11 Roll-spot
Spot welding with an output to operate motor-driven welding
wheels during the OFF time between weld sequences.

Retract
Some operational modes provide a Retract facility. This feature is used when a welding gun has
two “open” states, a wide open state for positioning the gun around a component, and a working
state.
There are three modes of Retract operation:
Simple Retract The Retract Output directly mimics the Retract Input. The Retract Output
must be off for welding to proceed. If the Retract Output is on the display will
read “Retract not ready”.
Hi Lift + With this mode of retract, an impulse on the Retract Input changes the state
of the Retract Output. In this case the Retract Output must be on for welding
to take place. If the Retract output is off, the display will read, “Retract not
ready”.
