- Page 21 TIG WELDING WELDING POLARITY DC ELECTRODE NEGATIVE POLARITY (DIRECT CURRENT STRAIGHT POLARITY) While Welding, there is a continuous flow of electrons from the electrode to the workpiece. This is the most used polarity, ensuring limited wear of the electrode, since the majority of the heat concentrates on the anode (workpiece).

- Page 23 MMA WELDING Insert an electrode into the electrode holder (Fig.12) ensuring there is a good connection. Select MMA by switching to the MMA welding mode (Fig.13). Set the amperage on the machine suitable for the electrode being used. Please see below a guide to amperages required.
- Page 24 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 25 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.
