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 off 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 off 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 off using the Weld Control Button
on the front panel. To turn the welder off, first unplug the power cord. If the Weld Control Button was not
pressed during charging, the welder will turn off automatically a few seconds after power is removed.
Otherwise, press and hold the Weld Control Button as normal to turn the unit off.
The welder may be left plugged in constantly; this will not damage the batteries.
4.9.2 Battery Alerts
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).
