5.2 Turning on the power source
Turn on the mains power by turning switch (7) to the ”START” position. Release the switch,
and it will return to the ”1” position.

5 OPERATION
0463 664 001 - 16 - © ESAB AB 2020
If the mains power supply should be interrupted while welding is in progress, and then be
restored, the power source will remain de-energised until the switch is again turned manually
to the ”START” position.
Turn the unit off by turning the switch to the ”0” position.
Whether in the event of a loss of power supply or of turning the power source off in the
normal manner, welding data will be stored so that it is available next time the unit is started.
5.3 Fan control
The power source fans continue to run for 6.5 minutes after welding has stopped, and the
unit switches to energy-saving mode. They start again when welding restarts.
The fans run at reduced speed for welding currents up to 180 A, and at full speed for higher
currents.
5.4 Overheating protection
The power source has two thermal overload trips which operate if the internal temperature
becomes too high, interrupting the welding current and lighting the orange indicating lamp on
the front of the unit. They reset automatically when the temperature has fallen.
5.5 Cooling unit
To ensure problem-free operation, the installation height from the cooling unit to the welding
torch must be max. 7 m. Heights in excess of this can cause problems, such as long starting
times, air bubbles, vacuums, etc.
If an installation height in excess of 7 m is required, we recommend an installation kit
comprising a non-return valve and a solenoid valve, refer to chapter "ACCESSORIES". Once
these valves have been installed, the hose package must be horizontal during the initial
startup so that everything fills with water. Then raise the wire feed unit and hose package to
the high height. Continued safe operation at installation heights of up to 12 m can now
commence.
Water connection (TIG welding)
The cooling unit is equipped with a detection system ELP (ESAB Logic Pump) which checks
that the water hoses are connected.
The power source On/Off switch must be in the “0” position (Off) when connecting a
water-cooled TIG torch.
If a water-cooled TIG torch is connected, the water pump starts automatically when the main
On/Off switch is turned to ”START” and/or when welding starts. After welding, the pump
continues to run for 6.5 minutes, and then switches to the energy-saving mode.
Function when welding
To start welding, the welder presses the welding torch 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 torch 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 OPERATION
0463 664 001 - 17 - © ESAB AB 2020
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.
For more information about the operation of the remote control unit, see the operating
instructions for the control panel.
5.7 WeldCloud™ unit
The WeldCloud™ unit connects the welding power source with a local WeldCloud™ server
through Wi-Fi or Wired LAN. The WeldCloud™ unit is equipped with GPS to track the
location of the welding power source. It also has Bluetooth connectivity to enable connection
with 3rd party input devices, for example a Bluetooth enabled barcode/QR scanner.
The WeldCloud™ unit Wi-Fi is enabled at power up of the power source. It will start as a
hotspot that appears as an available Wi-Fi network. After establishing connection, it is
possible to access the web interface of the power source for a one-time set-up. After set-up
and restart, the power source will be visible in WeldCloud™. For more information about the
WeldCloud™ unit and features, see the WeldCloud™ instruction manual.
