Kemppi Promig 300 Operation Instructions Manual

16 – PROMIG 200, PROMIG 300 / 0537 © KEMPPI OY3.4. LOCAL CONTROLS/I - potentiometer R11MIG/MAG: Local control for wire feed speed 0…18 m/min or 0…25 m/min (Promig 300)MMA welding: Welding current control, 10 A … max current of power sourceU - potentiometer R12MIG/MAG: Local control for voltage of PRO power source, 10 V …max. MIG voltage of power sourceMMA welding: No operation3.5. REGULATION FOR SHIELDING GAS FLOWShielding gas flow can be regulated with flow regulator 5…25 l/min. Display is calibrated forAr CO2 mixed gas (75% Ar, 25% CO2). By other gases the meter error remains within ±10%limits compared with real flow.The gas flow regulator shows within ± 10% limits right only when angle ofdeflection is smaller than 15° in regard to vertical.Regulate the meter always when the unit is in vertical position.Gas flow is read in the centre of swimmer.3.6. SIGNAL LAMP H12 INDICATING MISSING OFSHIELDING GASThe unit is equipped with shielding gas guard which by missing of shielding gasprevents welding start and stops welding, if arrival of shielding gas is preventedduring welding.Red signal lamp is illuminated:Welding is prevented until shielding gas pressure is adequate.Red signal lamp is not illuminated:Welding is allowed.3.7. SIGNAL LAMP H11 FOR ERRORSBy Promig 200 and 300 units check by each start, if there are error states in theequipment, if error states are observed, the error state is shown by blinking ofsignal lamp H11 for errors. E.g. one short flash means error code Err 1 and twoshort flashes indicate error code Err 2 etc.Error codes are:1 short flash, Err 1: Promig has gone over to MMA welding, though you have alreadyselected MMA welding on power source panel.2 short flashes, Err 2: You are pressing on start switch of gun, when data transmissionbetween Promig and PRO is broken (defect in control cable or inconnector), or you are pressing on gun switch, when MMA weldinghas been selected on control panel of power source.4 short flashes, Err 4: You are pressing on start switch of gun and selecting switch S12 forcooling mode is in liquid position and you have forgotten to switch-onthe PROCOOL cooling unit or you have forgotten to connect it toequipment.
