Hybrid Welder Battery Charging Instructions:
To charge the batteries in the Hybrid Welder, simply plug the power cord into a 120VAC or 240VAC outlet. The welder may
be switched on or off during charging; this does not affect the charge cycle. If the operator welds while the batteries are
charging, the charger will automatically shut off to protect the batteries. When 2 minutes have passed since the last weld,
charging will resume automatically. While the batteries are being charged, the LCD display will show the charging voltage
and current for each battery. During a normal cycle, the battery voltage can rise as high as 15.5V for several hours, and will
then be reduced to 14.4V for the remainder of the charging cycle. After 10 hours of charging, the voltage will be reduced to
13.8V to provide a "float" charge. If the charger is left plugged in for more than 24 hours, it will go into standby mode. In this
mode, the charger will provide a topping voltage to the batteries every 4 days to ensure that the welder will always be ready
for immediate use. The welder may be left plugged in constantly; this will not damage the batteries.

When batteries are fully charged they should be between 12.8 – 13.8V with the charger turned off.
When power cord is attached to 120VAC or 240VAC the batteries get charged automatically. The
status of charging is displayed on front panel display (unplugged). To test each battery under load,
select batteries 1-4 with the WELD switch. Note the voltage in the display screen. Push battery
TEST button located to the left of the weld switch for 2-3 seconds; note the load voltage on the
display screen (Fig. 1). If the voltage dips down under 12V, charge the batteries and check again. If
it is still low, check and/or replace the battery. The weld count indicates the total number of welds
on the unit.
VERY IMPORTANT: Do not use any other battery than those supplied by Pro Spot.
During the charge cycle or welder operation, the LCD may display status alerts to indicate when
user action is necessary to keep the batteries in good condition. These alerts are described below:
LOW VOLTAGE
This alert indicates that the battery has reached the maximum safe discharge level and needs to
be charged (Fig. 2). The welder will disable the depleted battery and sound an audible alert if the
operator tries to use this battery to weld. Any batteries not showing this alert can still be used to
weld. To clear this alert, plug in the power cord and allow the batteries to charge. When any low
battery is recharged to at least 13.8V, the alert will clear automatically and welding can resume.
SERVICE
This alert indicates that the battery voltage has fallen below 11.5V and the battery needs to be
replaced (Fig. 3). The charger will not attempt to charge a battery that has discharged this low, as
doing so might cause the battery or charger to overheat.
WARNING:
Warranty is voided if battery water level has not been maintained. Check battery water
level at consistent intervals (Fig. 4).
