be slowed so that the short may clear with minimum spatter.
Inductance also stores energy and then supplies this energy to the arc after the short has cleared, to create a longer arc. Inductance also increases the amount of arc-on time. This, in turn, makes the puddle more fluid, resulting in a flatter, smoother weld bead and perhaps better tie-in at the toes of the weld. The opposite is true when inductance is decreased.
When using solid mild-steel weld wire, use inductance to help control spatter. Generally, use higher induc- tance values with thicker workpieces and lower inductance on thin work. Solid stainless-steel wires are notorious for creating weld beads with a high crown and ropey bead appearance. Here, a longer arc-on time improves wet-out, flattens the crown and enhances bead aesthetics.
Programmable Memory and Synergic Lines
In job shops, welding operations differ from day to day. Each new job requires setup time and parameter test- ing. In large operations, manufacturers want all operators across all shifts and all plants to produce consistent results. While very different, both types of com- panies will benefit from a wire feeder/ controller that offers a programmable memory function, or a synergic machine.
Programmable memory can feature varying degrees of sophistication, from enabling a user to set and recall param- eters to providing parameter-adjust- ment limits. Either way, being able to recall parameters can save hours of setup time and more than a few pounds of scrap depositing test welds.
Synergic lines come with pro- grammed parameters established by factory technicians to deliver optimum results for specific combinations of wire type and diameter, welding process and shielding-gas composition. They also include preset values for creep start, burnback and the other functions noted above; these functions can be toggled on or off in some systems, and they can
