1 Consult factory for circuit breaker applications.
2 "Time-Delay" fuses are UL class "RK5" .
3 "Normal Operating" (general purpose – no intentional delay) fuses are UL class "K5" (up to and including 60 amp), and UL class "H" ( 65 amp and
above).

Weld Bead Using The End Stabilizer
Connection With 17 Volts, 100 Amps
Remove left side panel.
1 Stabilizer Z
Tapped stabilizer Z is factory con-
nected to the stabilizer tap which
suits most GMAW applications.
Stabilizer Z controls the inductance
applied to the weld current. To in-
crease inductance and wet out the
weld puddle, connect to stabilizer Z
ending.
To change inductance proceed as
follows:
2 Lead 24
3 Stabilizer Z Tap
4 Stabilizer Z Ending
5 Lead 25
To decrease inductance, connect
lead 25 to stabilizer tap and secure.
Reinstall side panel.
6 Typical Weld Bead Using The
Tap Stabilizer Connection
Use the tap Stabilizer connection
when welding with 100% CO
shielding gas.
Use either stabilizer connection,
depending upon your arc prefer-
ence, while welding with a mixed
shielding gas.
Use stabilizer Z ending to weld on
stainless steel.
7 Typical Weld Bead Using The
End High Stabilizer
Connection
Use the end Stabilizer connection
to reduce weld bead crowning, and
spread the weld puddle.
Install left side panel.
