User manual SEALEY SUPERMIG 150-5 VERSION 2

[. . . ] MODEL NO : INSTRUCTIONS FOR: SUPERMIG 150/5. V2 MIG WELDER Thank you for purchasing a Sealey Welder. Manufactured to a high standard this product will, if used according to these instructions and properly maintained, give you years of trouble free performance. USE THE PRODUCT CORRECTLY AND WITH CARE FOR THE PURPOSE FOR WHICH IT IS INTENDED. FAILURE TO DO SO MAY CAUSE DAMAGE OR PERSONAL INJURY, AND WILL INVALIDATE THE WARRANTY. [. . . ] Push the reel of wire over the threaded spindle and onto the flange of the inner circular plastic retainer. Tighten the nut whilst turning the reel until a slight braking pressure is felt. Ensure the spool rotates clockwise, with the wire drawing off the reel from the top as shown in fig 5. Reduce the wire feed tension by turning the wire feed knob ( fig. 6-A ) 2 or 3 turns anticlockwise. ( Do not unscrew the knob completely. ) Pull the knob towards you and allow it to disengage from the counter roller bracket and hinge downwards to the position shown in fig. 5. Push the counter roller bracket upwards and away from the grooved drive roller as shown in fig. 5. Ensure that the correct size of drive roller is installed and that the roller is the right way round to drive the the chosen wire. Before releasing the wire from the reel ensure that the reel is not freewheeling ( See section 3. 3. 1 ) As you release the wire keep a slight tension on it to prevent coils coming off the reel. Straighten the first 50mm of the wire and feed it into the flexible hose ( see fig. 5A ), over the grooved drive roller ( see fig. 5B ), and into the torch liner collet ( see fig. 5C ). Now hinge the counter roller bracket back down onto the wire and secure it by swinging the tension lever/knob up into the socket in the bracket. ( fig. 6-A ) Before feeding the wire through to the torch remove the gas cup (fig 3. 3. 5. a) and contact tip (b) from end of torch as follows: a) Take torch in left hand with the torch tip facing to the right. do not turn gas cup anti-clockwise, as this will damage internal spring. Check welder is switched off 0, and that the earth clamp is away from the torch tip. Connect the welder to the mains power supply and set the voltage switch to one. Keeping the torch cable as straight as possible and press the torch switch. b) Grasp gas cup in right hand, push onto torch head and turn clockwise only. do not turn gas cup anti-clockwise, as this will damage internal spring. c) Cut wire so that it is just protruding the cup. fig 2. fig 4 fig 5. fig 6. SUPERMIG150/5. V2 - (1) - 241002 3. 4 3. 4. 1 Setting wire tension IMPORTANT: You must set the correct tension, too little or too much tension will cause problematic wire feed and result in poor welding. The wire tension mechanism should only apply sufficient tension to the wire to successfully drive it out of the torch. A spool of welding wire is positioned on the welders spool holder and automatically fed through an insulated liner in the torch to the tip. The torch assembly consist of a switch, liner, gas hose, and control cable. The weld current is transferred to the electrode (the wire) from the contact tip at the end of the torch. [. . . ] Pull the connector from the end of the trigger spring and lift the cable, swan neck and brass block out of the moulding. ( See fig. 9. ) To remove the old liner cut it at approximately 2cm from the brass termination fitting screwed into the block and pull the old liner out of the sheath from the wire feed end. Unscrew the brass collet from the wire feed end of the liner and retain it for use on the new liner. Remove the remaining stub of the old liner by unscrewing it anticlockwise out of the brass termination fitting. [. . . ]
