PC Interfaces
CAUTION
Equipment damage or faults may occur if the PC is connected incorrectly!
Not using the SECINT X10USB interface results in equipment damage or faults in signal
transmission. The PC may be destroyed due to high frequency ignition pulses.
• Interface SECINT X10USB must be connected between the PC and the welding machine!
• The connection must only be made using the cables supplied (do not use any additional
extension cables)!
PC 300 welding parameter software
Create all welding parameters quickly on the PC and easily transfer them to one or more welding
machines (accessories: set consisting of software, interface, connection leads).
