The following effects will occur if the pressure adjustment screw is overtightened,
A: Suitable wire pressure and conduit dimensions. left loose or if the wrong wire feed roller is used.
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.

3.9 Adjustment of Gas Flow
Make the gas adjustment and gas test by lifting the wire feed roller pressure lever!
• 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.
