
Always keep the protective boots and dust caps on all connectors and fittings
until cables are ready to install. A major cause of downtime in any automatic
welding system is improper care and use of cables.

Take extreme care to avoid dropping the power supply or the weld heads.
Always disconnect the power input cable from the junction box or wall-
plug before cleaning the unit.
DO NOT USE acid, corrosives or any liquid substance on the Model 217 WDR
or any weld head. When cleaning, use only a light solution of isopropyl alcohol on a
soft cloth.
DO NOT ADD lubrication such as graphite, oil or grease to the weld head or
power supply unless it is specified in the operation manual for that equipment.
8.2 TROUBLESHOOTING
The Model 217 WDR has the ability to monitor certain functions. If they are not working
correctly a system fault will alert the operator to the problem.
When a System Fault occurs prior to or during welding it is required for the operator to clear
the fault condition before welding. When a fault occurs during sequence or attempting
sequence the FAULT SCREEN will appear.
Some faults are only temporary and the fault is corrected when the arc goes out. But all
faults will cause the FAULT SCREEN to appear and let the operator know why the
sequence was stopped.
The following is a general description of the cause of each type of fault and some
recommendation for correction. In all cases, when the fault is corrected the operator must
press the OK key to clear the FAULT SCREEN.
1. TEMP - The Model 217 WDR has an internal temperature sensor (thermal switch). If
the power supplies internal temperature rises above the safe limit, a TEMP fault
occurs. This can only occur if there is some type of blockage of air circulation, fan
failure or component failure within the power supply or the system is being operated in
ambient air temps above or below its rating of 0 degrees C (32F) and 45 degrees C
(104F), 95% humidity (non condensing).
