Info

8 Arc does not have a crisp sound, that short arc exhibits, when the wirefeed speed and voltage are adjusted correctly. The MIG torch has been connected to the wrong voltage polarity on the front panel. <strong>42</strong> Connect the MIG torch to the positive (+) welding terminal for solid wires and gas shielded flux cored wires. Refer to the electrode wire manufacturer for the correct polarity.
10.03 TIG Welding Problems Weld quality is dependent on the selection of the correct consumables, maintenance of equipment and proper welding technique. Description Possible Cause Remedy 1 Excessive beard build-up or poor penetration or poor fusion at edges of weld. 2 Weld bead too wide and flat or undercut at edges of weld or excessive burn through. 3 Weld bead too small or insufficient penetration or ripples in bead are widely spaced apart. 4 Weld bead too wide or excessive bead build up or excessive penetration in butt joint. 5 Uneven leg length in fillet joint. 6 Electrode melts when arc is struck. Welding current is too low. Increase weld current and/or faulty joint preparation. Welding current is too high. Decrease weld current. Travel speed too fast. Reduce travel speed. Travel speed too slow. Increase travel speed. Wrong placement of filler rod. Re-position filler rod. Electrode is connected to the Connect the electrode to the ‘+’ terminal. ‘−’ terminal. 7 Dirty weld pool. A Electrode contaminated A Clean the electrode by through contact with work piece or filler rod material. grinding off the contaminates. B Gas contaminated with air. B Check gas lines for cuts and loose fitting or change gas cylinder. 43
