ENShielding gas1.2.4.l/min51015203.Shielding gas is used for replacing air around the welding arc. For steel wires, use CO₂ (carbondioxide) or a mixture of Ar (argon) and CO₂ for shielding gas. Welding performance will beimproved when using mixed gas products. For stainless steel filler wires, use a mixture of Arand CO₂ (2 %), and for aluminium and CuSi filler wires, use pure argon. The required flow rateof the shielding gas is determined by the thickness of the welded sheet and the used weldingpower. Alternative gas mixtures are available. Contact your gas supplier for further advice.The machine is delivered with a 1.5 m gas hose. Connect the gas hose to the machine’s maleconnector at the back of the machine. Connect the other end of the gas hose to the gascylinder via a suitable and approved single stage regulator valve, where outlet flow rates canbe adjusted.NOTE! Never attempt to connect directly to a compressed gas cylinder. Always use an approvedand tested regulator and flow meter.Connecting the gas hose to a typical welding regulator control valve1. Connect the hose to the welding machine2. Open the regulator valve of the gas cylinder3. Measure the gas flow4. Adjust the flow with the adjustment knob (12–18 lpm)NOTE! Use a suitable shielding gas for the welding application. Always secure the gas cylinder inan upright position with either a specially made wall rack or the Kempact RA GasMate chassis,securing the cylinder in place with the webbing and metal buckles provided. Always close thecylinder valve after welding.Kempact 251R, 253R, 323R, 181A, 251A, 253A, 323A8
