Welding hose
A9-250
A9-400
Permissible load at 60% duty cycle
Length: 5 m, 10 m, 16 m
250 A
400 A
Electrode diameter
0.8-1.2 mm
0.8-1.6 mm
Working pressure
490 kPa (5 kp/cm
2
)
490 kPa (5 kp/cm

)
Max. testing pressure
735 kPa (5 kp/cm

NB.
Make sure the gun motor has the proper working pressure, 490 kPa (5 kp/cm
2
).
If the pressure is lower the motor will not get the right speed, resulting in too low wire
feed speed and welding current. If the pressure is higher the welding hose will be
exposed to harmful dynamic pressure.
