Cable Connections - STAMOS S-PLASMA 55H Manual De Instrucciones

Cable connections

1. Each plasma cutter is equipped with a main power cable, which is responsible for
providing current and voltage to the device and it must be connected to the suitable
power source according to plasma cutter input voltage.
2. The main power cable should be properly connected to the connection socket in or-
der to avoid oxidation. If possible, check using the measuring instrument if the voltage
fits in the appropriate range.

Operation
Turn on the switch at the back of the device, control light turns on and value of the
current (A) is visible.
Set the desired gas pressure and open the pressure valve.
Press the button on the cutting torch, valve turns on and arc can be seen and heard.
Set the cutting stream according to the workpiece thickness.
Place the cutting torch copper nozzle on the workpiece (in case of pilot arc, the cop-
per nozzle should be placed about 2 mm above the workpiece), press the button on
the torch until the arc will be ignited, raise the cutting nozzle approx. 1 mm above the
workpiece and start cutting.

A bipolar transistor with insulated gate electrode (insulated
gate bipolar transistor, IGBT) is a semiconductor that
is increasingly used in power electronics, as the bipolar
transistors offer certain advantages (e.g. good forwarding
characteristics, high blocking voltage, robustness in welding
equipment) and benefits characteristic of a field effect
transistor (control with virtually no power consumption).
Another advantage is a certain degree of resistance to short
circuits, as IGBT limits the load current. IGBTs are a further
development step of the vertical power MOSFETs.
STARKSTROM: = These devices use a 3-phase connection
(400V +/- 10%).
