PROMIG 520R, 120R / 0544 – 15© KEMPPI OYControl of welding dynamics R23When you adjust welding dynamics, adjustment value -9...0...9 is shown momenta-rily in the Voltage display which normally shows set value / welding voltage. Valueof dynamics is shown in display for approx. 3 s after adjustment.Control of MIG welding dynamics:With MIG welding dynamics control you can influence arc stability.-9...-1 Softer arc decreasing spatter0 Default setting for all wires1...9 Harder arc maximising stability of arc during short circuit and welding of steel with 100 %CO2 shield gas (settings 7...9).Digital display for wire feed speed, current and voltage P21, P22, P23/ m / min displayDisplay shows set value of wire feed speed switching to true value 0.0...18.0 m/min or 0.0...25.0m/min during welding.A displayDisplay shows 0 A (*no welding*) switching to true value of welding current during welding.V displayDisplay shows set value of welding voltage and true value during welding.Note! Display shows terminal voltage of power source. Depending on length and copper cross-section of welding cables real arc voltage and display may differ.

WELD DATA / GAS TESTRetrieval of welding parameters to displaysUse of WELD DATA switch retrieves welding parameters, wire feed speed, weldingcurrent, welding voltage which were used when welding was stopped last. Weldingvalues are indicated in display for so long you are using the WELD DATA switch,and are stored until you press again the start switch for gun.Testing the gas flowA short press on switch starts flow of shielding gas. The shielding gas flows for approximately 20seconds, or until the switch is pressed again.
