Turning on the power source
Turn on the main power by turning switch (7) to the "START" position. Release the switch,
and it will return to the "1" position.
If the main power supply is interrupted while welding is in progress, and then is restored, the
power source will remain de-energized until the switch is again turned manually to the
"START" position.
Turn the unit off by turning the switch to the "0" position.
If the supply power fails or the power source is turned off in the normal manner, the 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 resumes.
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 accessories in the
"ACCESSORIES" chapter. 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 begin.
Water connection (GTAW)
The cooling unit is equipped with an ELP (ESAB Logic Pump) detection system, which
checks that the water hoses are connected.
