OPERATION

OPERATION
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 the "WELD" position.
STARTING OPERATION
1)
Never actuate the unit without metal over the mandrel. For maximum weld quality, the metal should be in
flat contact with the 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 mandrel.
The WELD TIME knob controls the weld quality of the pinspotter. It is recommended that an initial setting
2)
right in the middle be used and then adjust up or down accordingly in reference to the quality of welds.
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 liner density you intend to use in the final production. The different densities and the 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 clip 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.
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 35 and 36 exhaust. 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 Dwell Solenoid are two Adjustable Mufflers.
The top one adjust the speed of the cylinder moving down and the bottom one adjust the speed up. These
mufflers can become restricted or loose. If the 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 31 and 32. 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 assembly 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.
