EN2.6 CABLE CONNECTIONSConnection to the mainsThe machine is fitted with a 3 m long supply voltage cable and plug. Connect the supplyvoltage cable to the mains. Should you need to fit an alternative plug or mains cable, ensureinstallation is completed by an authorised electrician.NOTE! The fuse size needed is 16 A delayed.If you use an extension cable, its cross-sectional area should be at least as large as themachines supply cable (3 x 1.5 mm²). It is recommended to use 3 x 2.5 mm² extension cable.The maximum length for the extension cable is 100 meters.The machine can also be used with a generator. The minimum power for the generator is4.2 kVA, and the recommended power 8.0 kVA in order for the machine to be used atmaximum capacity.Earth returnThe welding circuit earth return cable is already connected to the machine. Clean theworkpiece surface and fix the earth return clamp to the work piece in order to create awelding circuit.Welding gunThe welding gun is already connected to the machine. The filler wire, shielding gas andelectric current is delivered to the weld inside the welding gun cable. When you press the guntrigger, shielding gas starts to flow and filler wire feed begins. The arc ignites when the fillerwire touches the work piece. Inside the gun cable there is a factory-installed wire liner thatis best suited for welding with steel and CuSi filler wires. It can temporarily be used also withstainless steel and aluminium wires. However, this is not recommended because of greaterfriction and reduced welding performance, and it may finally lead into failure of filler wiredelivery.If you mainly use aluminium or stainless steel filler wire, we recommend that you replace thewire liner with a Kemppi plastic type, which is better suited for the material. For instructionson how to change the wire liner, please refer to the Maintenance section later in this manual.The gun neck can be rotated 360° to suit different welding positions. The neck is connected viaa standard clockwise screw thread. Always make sure that the neck is almost fully connectedto the bottom thread. This prevents damaging and overheating the neck.NOTE! If you intend to use other than 0.8 mm diameter steel filler wire, change the welding guncontact tip, gun liner, and drive roll to match the selected filler wire type and thickness.6MinarcMig Evo 200 / © Kemppi Oy / 1110
