Important!
In order to avoid destruction of
plugs and cables, good electric
contact is required when
connecting earth cables and
welding hoses to the machine.
Connection of welding hose
Configuration
MIGATRONIC disclaims all responsibility for damaged
cables and other damage related to welding with
undersized welding torches and welding cables
measured by welding specifications e.g. in relation to
permissible load.
Technical data apply to DC welding. Please note that
duty cycle is influenced by the process selected and
reduced by up to 30%, e.g. during pulse welding.
Correct installation of the contact tip
To ensure fine welding properties and to minimize
wear of the contact tip, good contact between
contact tip and tip adaptor as well as good electrical
contact between contact tip and welding wire are
important. Choose a contact tip with a diameter
that suits the wire. Please note: the contact tip must
be equipped with a suitable torque, ensuring good
contact to the tip adaptor. In case of insufficient
contact, the contact tip will soon be damaged by too
high temperature.
