- Page 17 OPERATION After the welding wire spool has been correctly installed in the machine close the side panel of the machine and plug into the mains outlet. Press the MIG/MMA switch to MIG mode, Fig.7. Turn the welder On using the On/Off switch (Fig. 8) then holding the torch straight out from the welder press the trigger on the torch, Fig.9.
- Page 18 OPERATION ATTACHING GAS BOTTLE AND REGULATOR Fit a suitable regulator and gas supply tube onto your gas bottle (Please note; regulator and gas bottle not supplied). Attach the other end of your gas supply tube onto the gas pipe attachment point on the back of the welder (Fig.10).
- Page 19 MIG WELDING Set the correct gas flow (when required),amperage output and voltage output for the material you are welding. The gas shield required will be either CO2 or Argon or a mix of CO2 & Argon. Use the correct gas (when required) for the material to be welded.

Decrease sound that the arc makes will change from a the speed until a regular, strong buzzing sound is sputtering to a high-pitched buzzing sound and heard.

- Page 23 MMA WELDING A WORD TO BEGINNERS For those who have not yet done any welding, the simplest way to commence is to run beads on a piece of scrap plate. Use mild steel plate about 6.0mm thick and a 3.2mm electrode. Clean any paint, loose scale or grease off the plate and set it firmly on the work bench so that welding can be carried out in the downhand position.
- Page 24 MMA WELDING ARC LENGTH The securing of an arc length necessary to produce a neat weld soon becomes almost automatic. You will find that a long arc produces more heat. A very long arc produces a crackling or spluttering noise and the weld metal comes across in large, irregular blobs.
