3.3.3 Control knobs• The left-hand control knob (P8) allows adjustment of the speed of wire feeding. Theselected speed is shown on the display on the left-hand side (P2).• The control knob on the right-hand side (P9) allows you to adjust the welding voltage. Theselected voltage is shown on the right-hand display (P6).These adjusters are used also for selecting the values of the machine’s operational parameters,such as the MIG mode and set-up features. A parameter for adjustment is selected with theleft-hand knob knob (P8), while the value of the parameter is selected with the right-handknob (P9).3.3.4 adjustment of Mig dynamics (arc force)When you press button P3, you can adjust the MIG welding dynamics of the machine bymeans of the right-hand knob, P9. The welding dynamics setting affects the properties of thewelding arc and the amount of spatter as follows:• The value 0 is the recommended basic setting.• Use values -1 … -9 if you want a softer arc and less spatter.• Use values 1 … 9 if you want a rougher and more stable arc. This setting is useful whenyou are using 100% CO₂-shielding gas when welding steel.3.3.5 gas testThe gas test button (P4) opens the gas valve without activating the wire feed or power source.By default, gas flows for 20 seconds. The gas flow time remaining is shown on the display.The right-hand knob (P9) allows you to set the default gas flow time, between 10 - 60 seconds,and store the new default value in the machine’s memory. To abort the gas test, press the startbutton or gun switch.3.3.6 Wire inchWhen you press the Wire inch button, P5, the wire feeder engine starts but the gas valve doesnot open and the power source is not activated. The default wire feed speed is 5 m/min, andyou can adjust the speed with the right-hand knob. When the button is released, the wirefeeding stops. The machine automatically goes back to the normal state after approximatelyfive seconds from release of the button or immediately when you press the start button.3.3.7 selection of liquid- or gas-cooled Mig gunYou can select a MIG gun cooled with liquid or gas by pressing buttons 3 and 5 simultaneouslyand holding them down for at least one second.• When the display reads ‘GAS’, you can use a gas-cooled MIG gun with the equipment.• When the display reads ‘COOLEr’, you can use a liquid-cooled MIG gun with theequipment.You can change the gun selection by pressing buttons P3 and P4 again, as above. With aliquid-cooled gun selected, the liquid cooling function is started when the power source isstarted the next time.3.3.8 retrieval of weld dataThe weld data function allows you to return to the welding current and voltage used duringthe previous session, with the weld data feature. To use the feature, press buttons P4 and P5simultaneously.3.3.9 selection of control panelButton P10 allows you to switch control between the control panels in the power source andwire feeder. The indicator shows which of the control panels is in use.• When the ‘LOCAL’ light is on, the wire feeding speed and welding current are set usingknobs P8 and P9 of the power source control panel.• When the ‘REMOTE’ light is on, the wire feed speed and welding current are set using thecontrol panel of the wire feeder. Control knobs of the power source are disabled in thismode.EN10FastMig KM 300, 400, 500 / © Kemppi Oy / 0901FISVNODAENDENLFRESPLRU
