FEED 400 error codes
By every start there is checking of possible error states in equipment. If an error state is found, the error in
question is shown with Err text appearing in the panel display.
Here are some of the error codes:
Err 2: The operator is pressing on gun switch, when MMA welding has been select-
ed from the FEED control panel.
Err 8: Liquid-cooled PMT gun is overheated.
Err 9: Overloading of wire feed motor, which can be e.g. due to blocked wire guide
tube of gun, or due to too sharply bent gun cable.
Err 12: The welding is prevented, because the shielding gas control of the gas
guard GG 400 has released.
The error codes disappear by following start, when reason of the error code is eliminated.
ACCESSORIES
SYNC400 synchronizing unit
By means of Sync400 you can connect the push-pull gun to the FEED wire feeder. The push-pull gun is most
commonly used for feeding of aluminium wires. The push-pull gun enables extending the working radius up to
10 m. The Sync400 is mounted into electronics case of the FEED. Mounting of the Sync400 is described in the
mounting instructions which are delivered with the unit.
GG400 gas guard
With gas guard accessory can be avoided weld defects due to lacking or wrong flow of shielding gas. Functions
of gas guard are as follows:
