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.

3.8 Adjustment Of Gas Flow
• Adjust the flow rate with the flow regulating valve.
• The practical gas (CO2, Ar, mixture) flow rate is 10 times the wire diameter.
For example, if the wire diameter is 0.9 mm, the gas flow rate can be set to
10x0.9= 9 l/min.
• You can use the table on the right for more precise flow adjustment.
• After adjusting the flow rate, lift the take-up roller lever and close the wire
feeder cover.
