3.3.10 setting of the Mig operating mode
Button P7 allows you to set the MIG welding gun to either two-sequence or four-sequence
mode. The indicator shows the mode selected.
• In two-sequence mode (2T), welding is started by pressing the gun switch and stopped
by releasing the switch.
• In four-sequence mode (4T), the following actions take place:
1. When you press the gun switch, the shielding gas starts to flow.
2. When you release the switch, welding starts.
3. When you press the switch again, welding ends.
4. When you release the switch again, the flow of the shielding gas ends.
3.3.11 setting of operation parameters
Button P7 also is used for changing welding parameters as follows:
• Depress button P7 for at least five seconds. The set-up menu appears on display P2.
• Select the parameter to adjust with the left-hand knob (P8) so that the name of the
parameter you want to adjust is shown on display P2.
• Set a value for the parameter by using the right-hand knob (P9) such that the value you
want is shown on display P2. The value you selected is recorded in the control panel
memory.
• Exit the set-up menu by pressing button P7 again and holding for at least five seconds or
by briefly pressing the control panel start button (P1).
