INTRODUCTION INTRODUCTION The MLC 302 is a component of the A9 semi--automatic series ”push--pull”--system. This means that a motor driven wire feed unit pushes the wire through the welding hose to the gun, and from there the compressed air motor in the welding gun pulls the wire out to the contact tip. The push--pull system ensures smooth, problem--free wire feed, which is especially important when welding soft consumables such as aluminium and thin wires.
TECHNICAL DESCRIPTION TECHNICAL DESCRIPTION The MLC’s aluminium casing is divided vertically into two sections. One section, which is protected by a screwed panel, contains the electrical and pneumatic regulating equipment. The other section is covered at the top and side by a hinged panel. In the closed position this panel is secured to the bottom panel by a snap lock. This section contains the hub for the wire reel, the wire feed mechanism with electric motor and connecting block for welding hose.

INSTALLATION INSTALLATION Connecting the welding hose 1. Open the side of the wire feed unit that contains the wire feed mechanism. Undo the locking screw on the connecting block. 2. Choose the appropriate inlet nozzle for the wire being used and push it securely into the welding hose. 3. Connect the welding hose to the wire feed unit and tighten the locking screw on the connecting block. 4. Remove the plastic cover from the gun housing, undo the locking screw and push in the other end of the welding hose.
MAINTENANCE MAINTENANCE Replacing the wire The wire conduit is made of plastic and can be damaged by sharp objects. Remove any burrs or sharp edges from the tip of the wire using a file, before feeding the new wire into the wire conduit. 1. Release the pressure roller springs. 2. Withdraw any remaining wire from the conduit. Remove the wire reel. 3. Fit the new wire reel. 4. Straighten out the first 5--10 cm of the wire and file off any sharp edges from the tip of the wire. 5.
