Adjustment Of Gas Flow; Using Trigger Modes - Magmaweld RS 350 M PRO Manuel D'utilisation

RS 350 M / MW PRO - RS 450 M / MW PRO - RS 550 M / MW PRO
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

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.

3.7 Using Trigger Modes

• The trigger mode switch selects 2-position, 4-position or pnt position.
• The 2-position operates as shown in Figure 23.
• The 4-position operates as shown in Figure 24. 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.
