USERS MANUAL
Resetting The Machine
All work programs are preset at the factory; however, on
any program, welding time and welding current can be
modified. Modifications are automatically memorized and
will replace factory settings. To recover factory settings,
proceed as follows:
1. Turn off main switch.
2. Turn on main switch
3. Before pressing control panel key “on”, press simulta-
neously the two bottom center keys for selection of job
(see items D and E on previous page). While keeping
these two keys depressed, press “on” key of control
panel. The machine will switch “on” and the message
“INIT PARA” will appear briefly on display panel. This
indicates the machine has recovered its factory settings
and is ready for use.
Welding On Two Sides
1. Adjust and tighten the arms of the two-sided gun after
making sure electrodes are correctly aligned.
2. Set air pressure to 70 psi (5 bar) for 9” arms. Increase
pressure by 15 psi for each 4” additional length.
3. Set program and thickness of sheets to be welded. In
case of different thicknesses, only consider the thinner
sheet. The power and welding time are preset and the
parameters will automatically appear on the display. If
preset parameters have been changed, set power and
time according to the chart at right or reset the timer as
indicated at top of this page to recover the original fac-
tory settings.
4. Position electrodes where welding is required and
pull trigger to complete welding process.
NOTE: A timer allows the trigger of the two sided gun
to be pulled and released during a 1.5 second span
without starting the welding process. This allows the
operator to reposition the gun on the parts to be
assembled. When pulling the trigger longer than 1.5
seconds, the gun remains closed and opens only
after the welding process is complete.
5. If electrodes stick to welded area, press button located
at top of handle to force the gun open.

A special work mode allows closing of gun without starting the
welding process to check proper alignment of electrodes. When
timer is on and pincer gun has been selected, use “D” Key (see
diagram - page 3) to select welding of mild steel (first pictograph
at left). Press “D” Key one more time. LED under pictograph will
start blinking showing the gun is at “no weld” position. The gun
can be closed for 5 seconds by keeping finger on trigger.
