4.9.1 Checking the Battery Voltage

The Hybrid Spot welder is equipped with an on-board charging system that will charge all 4 batteries
at once.
To activate charging, simply plug in the power cord to the outlet on the back of the welder Fig 3.2 and
the supply 120VAC or 240VAC for Europe, Australia, and China. The power supply switches automatically
between 120VAC and 240VAC. The charger cooling fans on the back of the unit will turn on automatically
when any charger is delivering more than 5 Amps to a battery, and will turn o when no charger is
delivering more than 4 Amps. This may happen several times during a single charging cycle.
It is possible to weld while the charging is activated; the charger will automatically switch o when
welding. The chargers will turn back on 1 minute after the last weld is made.
NOTE: While the welder is plugged in, it is not possible to turn the unit o using the Weld Control Button
on the front panel. To turn the welder o , rst unplug the power cord. If the Weld Control Button was not
pressed during charging, the welder will turn o automatically a few seconds after power is removed.
Otherwise, press and hold the Weld Control Button as normal to turn the unit o .
The welder may be left plugged in constantly; this will not damage the batteries.

OPERATION
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).
