C:
The thrust bearing arm is tightened too tightly; the surface of the reel is distorted.
D:
The channel length of the reel is too short for the wire used. The shape of the wire is distorted.

Figure 12 : Thrust Adjustment and Reel Selection Faults
Perform the gas adjustment and gas test by lowering the thrust bearing arm of the wire
feed reel!
3.7 Setting Gas Flow
• Adjust the gas flow with the flow control valve.
• Practical gas flow rate (CO₂, Ar, mixture) is 10
times the wire diameter.
For example, if the wire diameter is 1.0 mm, the
gas flow rate can be adjusted as
1.0 x 10 = 10 lt./min.
• You can use the table on the side for more precise
flow adjustment.
• After adjusting the gas flow, lift the thrust bearing
arm and close the wire feed unit door.
Note: Recommended values in standard conditions.
