CPTX 270/CPTX 330
4.2 The transformer
The CPTX 270/CPTX 330 includes a motor insulation class "H", the primary and secondary
windings run electrically isolated from each other. The CPTX 270/CPTX 330 is designed for
a mains voltage of 3x400V.
4.3 Rectifier
The rectifier at the CPTX 270/CPTX 330 is manufactured from insertion diodes and heat
sinks and is used for rectification of the welding current.
4.4 Choke
The integrated inductance improves the dynamics of the power source CPTX 270/CPTX 330.
4.5 Control board
The existing control board controls the wire feed speed and allows the spot and interval
welding.
4.6 Wire feed mechanism with motor
The wire feed mechanism with a motor is used for the wire feeder. The corresponding
pressure of the feed rollers on the wire is adjusted by rotating the adjusting nut. For different
wire diameters, appropriate feed rollers to be used.
4.7 Electromagnetic gas valve
The electromagnetic gas valve controls the necessary gas supply. The corresponding
amount of gas pressure is adjusted with the pressure regulator.
