GB5.4Polarity changeThe power source is delivered with the welding wire connected to the plus pole.Some wires, e.g self shielded cored wires, are recommended for welding withnegative polarity. Negative polarity means that the wire is connected to the minuspole and the return cable to the plus pole.Check the recommended polarity for the welding wire you want to use.5.5Wire feed pressureStart by making sure that the wire moves smoothly through the wire guide. Thenset the pressure of the wire feeder's pressure rollers. It is important that thepressure is not too ÏÏFig 1Fig 2To check that the feed pressure is set correctly, you can feed out the wire againstan insulated object, e.g. a piece of wood.When you hold the gun approx. 5 mm from the piece of wood (fig. 1) the feedrollers should slip.If you hold the gun approx. 50 mm from the piece of wood, the wire should befed out and bend (fig. 2).- 13 bc23de ESAB AB 2011

File off any burrs and sharp edges from theend of the wire before inserting it into the wire feed unit.Make sure that the wire goes properly into the feed roller track and into the outletnozzle and the wire guide.Secure the pressure sensor.Close the side panel.6MAINTENANCERegular maintenance is important for safe, reliable operation.CAUTIONAll guarantee undertakings from the supplier cease to apply if the customer attempts anywork to rectify any faults in the product during the guarantee period.6.1Inspection and cleaningPower sourceCheck regularly that the power source is free from dirt.The power source should be regularly blown clean using dry compressed air at reducedpressure. This should be done more frequently in dirty environments.Otherwise the air inlet/outlet may become blocked and cause overheating. To avoidthis you can use an airfilter.The airfilter is an accessory. Order number can be found on page 29.Welding gunSThe welding gun's wear parts should be cleaned and replaced at regularintervals in order to achieve trouble-free wire feed. Blow the wire guide cleanregularly and clean the contact tip.The brake hubThe hub is adjusted when delivered, ifreadjustment is required, follow the instructionsbelow. Adjust the brake hub so that wire is slightlyslack when wire feed stops.SAdjusting the braking torque:STurn the red handle to the locked position.SInsert a screwdriver into the springs in the hub.Turn the springs clockwise to reduce the braking torqueTurn the springs counter-clockwise to increase the braking torque. NB: Turnboth springs the same amount.- 14 bc23de ESAB AB 2011
GB7FAULT TRACINGTry these recommended checks and inspections before sending for an authorisedservice technican.Type of faultActionsSSNo arcSWelding current is interruptedduring weldingSSCheck that the mains power supply switch is turned on.Check that the welding current supply and return cables arecorrectly connected.Check that correct current value is set.Check whether the thermal overload trip has operated(indicated by the orange lamp on the front).Check the main power supply fuses.Thermal overload tripsoperate frequentlySSCheck to see whether the air filters are clogged.Make sure that you are not exceeding the rated data for thepower source (i.e. that the unit is not being overloaded).Poor welding performanceSCheck that the welding current supply and return cables arecorrectly connected.Check that the correct current value is set.Check that the correct welding wires are being used.Check the main power supply fuses.Check the wire feed unit - if proper rolls are applied andproperly set the pressure of the wire feeder's pressure rollersSSSS8ORDERING OF SPARE PARTSRepair and electrical work should be performed by an authorised ESAB servicetechnician. Use only ESAB original spare and wear parts.Mig C280 PRO, Mig C340 PRO is designed and tested in accordance with the interna tional and European standards 60974-1, 60974-5 and 60974-10 .
