The following effects will occur if the pressure adjustment screw is overtightened, left loose or if the wrong
wire feed roller is used.
Make the gas adjustment and gas test by lifting the wire feed roller pressure lever!
A:
Suitable wire pressure and conduit dimensions.
B:
The wire is distorted since the pressure lever is too tight.
C:
The roller surface is deteriorated due to excessive pressure on the pressure lever.
D:
The conduit length of the roller is small for the wire used. Wire form is distorted.
E:
The conduit length of the roller is big for the wire used. The wire cannot be transmitted to the welding area.

3.9 Adjustment of Gas Flow
• Adjust the gas flow with the flow control valve.
• Practical gas flow rate (CO₂, Ar, mixture) is 10 times of wire diameter.
For example, if the wire diameter is 0.9 mm, the gas flow rate can be
adjusted as 10 x 0.9 = 9 l/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.
