1. Power Switch ON/OFF (I/O): Controls the input
power to the machine. Be sure the power source is
connected to the mains supply before turning power
on ("I"). After input power is connected and the
power switch is turned on, the power switch will light
up to indicate the machine is ready to weld.
2. Thermal Overload Indicator: This lamp
will light up when the machine is
overheated and the output has been
turned off. This can occur if the ambient
temperature is above 40°C or the duty cycle of the
machine has been exceeded. Leave the machine on
to allow the internal components to cool, when the
lamp turns off normal operation is possible.
3. Welding Load Voltage Switch: Adjust the
welding load voltage. POWERTEC 205C
has 1 switch (10 steps). POWERTEC
255C and 305C have 2 switches (2 and 10 steps).
WARNING
Do not switch Welding Load Voltage [3] during welding.
4. WFS (Wire Feeding Speed) Control
Knob: It enables continuous control of
wire feeding speed in the range from 1 to
20 m/min.
5. Digital Display Panel: Available as an option(see
"Accessories" chapter).
6. EURO Socket: For connecting a welding gun (for
GMAW, FCAW-GS / FCAW-SS process).
