EN3.9.1 Installing gas cylinderNOTE! Always fasten gas cylinder properly in vertical position in a special holder on the wall or on acarriage. Remember to close gas cylinder valve after having finished welding.Parts of gas flow regulatorEBDGA FCA. Gas cylinder valveB. Press regulation screwC. Connecting nutD. Hose spindleE. Jacket nutF. Gas cylinder pressure meterG. Gas hose pressure meterThe following installing instructions are valid for most of the gas flow regulator types:1. Step aside and open the cylinder valve (A) for a while to blow out possible impuritiesfrom the cylinder valve.2. Turn the press regulation screw (B) of the regulator until no spring pressure can be felt.3. Close needle valve, if there is one in the regulator.4. Install the regulator on cylinder valve and tighten connecting nut (C) with a wrench.5. Install hose spindle (D) and jacket nut (E) into gas hose and tighten with hose clamp.6. Connect the hose with the regulator and the other end with the wire feed unit. Tightenthe jacket nut.7. Open cylinder valve slowly. Gas cylinder pressure meter (F) shows the cylinder pressure.Note! Do not use the whole contents of the cylinder. The cylinder should be filled whenthe cylinder pressure is 2 bar.8. Open needle valve if there is one in the regulator.9. Turn regulation screw (B) until hose pressure meter (G) shows the required flow (orpressure). When regulating flow amount, the power source should be in switched on andthe gun switch pressed simultaneously.Close cylinder valve after having finished welding. If the machine will be out of use for a longtime, unscrew the pressure regulation screw.3.10 Main switch I/OWhen you turn the main switch of the FastMig power source into I-position, the pilot lampclosest to this switch will light up, indicating the power source is ready for welding.NOTE! Always start and switch off the machine with the main switch, never use the mains plug as aswitch.9© Kemppi Oy / 1152
