Function when welding
To start welding, the welder presses the welding gun trigger switch. The power
source turns on and starts the wire feed and the cooling water pump.
To stop welding, the welder releases the welding gun trigger switch. Welding ceases,
but the cooling water pump continues to run for 6,5 minutes, after which the unit
switches to energy-saving mode.
Water flow guard
The water flow guard interrupts the welding current in the event of loss of coolant,
and displays an error message on the control panel. The water flow guard is an
accessory.
5.6 Remote control unit
When the remote control unit is connected, the power source and wire feed unit are
in remote control mode; the buttons and knobs are blocked. The functions can only
be adjusted via the remote unit.
If the remote control unit is not to be used, the remote control unit must be
disconnected from the power source / wire feed unit, as otherwise it will remain in
remote control mode.
When a remote control unit is used to set the voltage, the function will be changed to
the setting of current during MMA welding.
For more information about the operation of the remote control unit, see the
operating instructions for the control panel.
