SERVICING
A SIMPLIFIED STEP-BY-STEP PROCEDURE
Duro Dyne has called upon its many years of pinspotting experience in designing the Mach I and Mach II.
Your unit has been rigorously factory tested and inspected to provide many years of dependable service.
WHAT TO DO BEFORE YOU BEGIN TROUBLESHOOTING:
CONSULT THE MANUAL.
Most of the functional problems that occur are due to an oversight in the set-up, operational or normal
maintenance procedures. Therefore, you should re-check all “Set Up”, “Initial Adjustment”, “Operation” and
“Maintenance” procedures.
INSPECT THE UNIT
If the problem still persists, the next step is careful visual inspection. Turn off the electricity - that is,
disconnect your Pinspotter from its power supply and carefully check the control box for loose, broken or
disconnected wires. Also check the air circuit for leaky air connections or cut hoses.
HOW TO IDENTIFY WELD QUALITY PROBLEMS
By weld we mean that the Power Pack is energized, sending a pulse of electricity through the clip pin, causing
it to begin to fuse to the sheet metal.
To properly troubleshoot the weld quality problems, you must first pinpoint the symptom by test welding the
clip pins to bare sheet metal. The symptom will then show up in one of four categories:
1) The pins weld to bare metal but not on lined work.
2) The pins weld to bare metal but can easily be removed.
3) Pins weld to bare metal but remain on the weld tip as it retracts.
4) The pins do not weld at all.
Before troubleshooting, always check:
1)
Air pressure for a minimum of 80 PSI during usage of unit.
2) The input Voltage for a minimum of 208V and a maximum of 230V.
3)
The Weld Timer is set properly.
4) The Upper and the Lower Weld tips for extreme wear.
It may become necessary to use a voltmeter and/or ohmmeter to perform some servicing procedures.
An Analog type is best. Our Technical Services Department will help you if necessary.
TROUBLESHOOTING SECTION
Your Mach I or Mach II Pinspotter is equipped with a Digital Function Display that will assist you in quickly
locating the probable cause should your machine fail to operate. While the display can point you to a defective
component, it is recommended that an analog type volt meter be used to verify the indication. In some cases
a loose or broken wire could cause a false indication.
This troubleshooting section has been divided into separate sections depending on the type of malfunction.
MACHINE DOES NOT OPERATE
PIN FEED PROBLEMS
DWELL CYLINDER PROBLEMS
PINS DO NOT WELD
POOR WELD QUALITY
VIBRATOR PROBLEMS
After determining the type of problem, go to that section, cycle the machine watching the indicator lights and
then follow the instructions in that part of the chart. If further assistance is needed you may call our Technical
Services Department at 1-800-899-3876 between the hours of 7am - 6pm EST.
