OPERATIONOPERATION
Mach 70 INITIAL ADJUSTMENTS
1) Turn the power switch to “ON”.
2) Turn the vibrator switch to “ON”.
3) Add the weld pins to the hopper (Vibrator Bowl).
4) Adjust the vibrator speed so that the weld pins climb the spiral track inside the vibrator bowl without
vibrating off.
5) When the weld pins fill the track up to the Vibrator Sensor, the vibrator automatically shuts off.
6) Flip the HEAD TEST Switch to either the “WELD #1” or “WELD #2” position.
NOTE: The Rolling Head Mach 70 Pinspotter has two redundant weld circuits. In the event that the solid
state relay controlling the weld fails you may simply flip the switch to the other circuit and continue
production. A replacement Weld Relay should then be ordered through your local Duro Dyne wholesaler.
INSTALLATION INSTRUCTIONSINSTALLATION INSTRUCTIONS
1) For the Mach 70-
Connect the Power Pack to a source of 208-240V 60 Amp. power. This service should be connected to
a 60 amp disconnect box fitted with 60 amp slow blow fuses. The Power supply line to the power pack
pigtail should be #6 (or heavier) wire to minimize voltage losses. The black and white wires are the power,
the green is ground. Select 208V or 240V at the voltage switch in the console on left leg to the closest
match to the power supply voltage.
2) Attach the Actuator Arm to the socket on the top of the Trolley.
3) Connect the air line to the Regulator. Adjust the regulator pressure to 80-85 PSI.
4) Plug the Vibrator Power Plug into the socket on the rear of the Control Panel.

STARTING OPERATION
1) Never actuate the unit without metal over the mandrel or lower copper ground bar. For maximum weld
quality, the metal should be in flat contact with the ground bar and mandrel. An adjacent table or roller on
which the sheet metal rests must be either exactly flush with, or slightly below, the top of the ground bar
and mandrel.
2) The WELD TIME knob controls the weld quality of the pinspotter. It is recommended that an initial setting
right in the middle be used and then adjust up or down accordingly in reference to the quality of welds.

MAINTENANCEMAINTENANCE
1) To prolong the weld tip life and improve the weld quality, it is imperative that the weld tips and lower ground
bar always be kept clean. For best results, use a solvent to remove any built-up adhesive; a wire brush to
remove any galvanizing deposits; and a fine emory cloth to smooth the tip and ground bar surfaces.
2) When lower weld tip becomes worn in one area, loosen the locking cap screw and rotate the point of wear
away from the point of contact. Additional lower weld plates can be ordered from your local distributor.
3) Depending on usage and maintenance, the upper welding tip plate will have to be periodically replaced. Re-
placement weld tip plates can be ordered from your local distributor. To replace the upper weld tip, loosen
the locking cap screw and remove the weld tip. Remove the plate by loosening three (3) brass screws.
Throw away the screws and attach the new plate to the tip using the three brass screws supplied. Be
sure to align the angled section of the plate so it faces the feed mechanism. Then lock the tip in place.
Cycle the machine to check the feeding.
4) If feeding is erratic, re-adjust the upper weld tip height by loosening the lock nut on bottom of the dwell
cylinder shaft and then turning the dweld cylinder shaft clockwise to raise the tip; counter-clockwise to
lower the tip. Lock the tip in place with the locking nut.
STARTING OPERATION (continued)
Weld time is the length of time the welding transformers are on. A fraction of a second is generally all the
time needed for a quality weld. Unnecessary weld time not only wastes energy but can also burn up the
pins. (If the pins glow red up to the washer, the weld time is set too high.) Always set the weld timer to
the minimum time required for a good weld.
3) Before beginning production, always “pre-test” with smaller pieces of the same gauge sheet metal thickness
and the liner density you intend to use in the final production. The different densities and thicknesses of the
liner may require adjustments of the weld timer setting. For example: heavier gauge steel, thicker liner,
higher density liner and/or longer weld pins may require longer weld time. To make sure, always pre-test
any adjustment before you begin “final production.” However, only change the weld timer settings when a
change in the materials results in inefficient welding or a poor quality weld.

SERVICINGSERVICING
A SIMPLIFIED STEP-BY-STEP PROCEDURE
Duro Dyne has called upon its many years of pinspotting experience in designing the Mach 70 Rolling Head.
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 Weld Transformer is energized, sending a pulse of electricity through the weld
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
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.
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 Dept will help you if necessary.
TROUBLESHOOTINGTROUBLESHOOTING
For assistance please call Duro Dyne Technical Services Dept at 1-800-899-3876 between the hours of
7am - 6pm EST.
NOTES:NOTES:
1. The Feed Reed Switch is a safety that will not allow the machine to operate if the feed cylinder is not fully
retracted. The Feed Reed Switch is located on the Feed Cylinder. To check that the Feed Reed Switch is
positioned properly, loosen the set screws and put an Ohm meter on terminals 7 and 9 in the trolley. Slide
the Feed Reed Switch back and forth until continuity is indicated, then tighten the set screws.
2. Check that the Air Regulator is set for 80 psi. Mounted on the top of the Trolley are two Adjustable Ex-
haust Mufflers. The front one adjust the speed of the Dwell Cylinder moving down and the rear one adjust
the speed up. These mufflers can become restricted or loose. If machine is sluggish or starts slamming
down, adjust these mufflers accordingly.
3. The First Pulse Reed Switch is located in the middle of the Dwell cylinder.
4. To check that the Dwell Reed Switch is positioned properly, loosen the set screws and put an Ohm meter
on terminals 6 and 11. Slide the Dwell Reed Switch up and down until continuity is indicated, then tighten
the set screws.
5. Mounted on the Feed Cylinder is a Feed Speed Control. The Feed Speed Control adjusts how fast the Pusher
with Pawl moves in and out. If adjusted too fast the pins may be tossed past the tip, if adjusted too slow
the pins will not be placed on the tip.
