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. The shape of the wire is distorted.
E:
The conduit length of the roller is big for the wire used. The wire cannot be transmitted to the welding area.
3.6 Adjustment of Gas Flow
3.7 Using Trigger Modes
• 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.
• The trigger mode switch selects 2-position, 4-position or pnt position.
• The 2-position operates as shown in Figure 17.
• The 4-position operates as shown in Figure 18. The 4-position provides ease of use for the welder in
long-term and automatic welding operations.
• In the pnt mode, the welding starts at the moment the trigger is pressed, the welding continues until the set
time period is on and stands by as long as the off-time period. The process continues in this manner until the
trigger is released and the welding stops as soon as the trigger is released.
