3.3.12 Calibration of the wire feed speed
When factory settings are used, the wire feed speed can be adjusted to between 4 and 100
without a unit of measurement. Only the LED symbol indicates that wire feed speed is the
parameter to be set.
The unit of the wire feed speed (m/min) is shown once the wire feed speed of the device has
beencalibrated.Toprogrammaticallycalibratethewirefeedspeed:
1. Topreparetheweldingequipmentforcalibrating,dothefollowing:
• Connectthewirefeedertothepowersourcewiththecontrolcable.

4. TROUBLESHOOTING
In the event of a failure of the machine, contact an authorised Kemppi service agent. Before
taking your unit for servicing, check the list below.
4.1 OVERLOAD YELLOW INDICATOR LIT
Two simultaneously operating fans cool the power source. The machine may, however,
overheat if continuously loaded above the rated values or if the circulation of cooling air is
prevented.
Theyellowindicator(A10)islitintheeventofoverheating.Youthenneedtostopweldingand
let the machine cool down. The indicator light turns o when welding can be resumed.
4.2 CONTROL CABLE CONNECTOR FUSE
The rear wall of the power source contains fuse A9, which protects the control cable
connector, A7. Using an incorrect fuse may cause damage to the power source. It is important
thatyoualwaysusetherightkindoffuse.Thetypeandsizeofthefuseareindicatednextto
