be adjusted in others.
Several control panels enable one-
knob synergic control and will auto- matically adjust all welding parameters, including those for pulsed welding. Basically, the welder turns the knob one way to weld hotter and faster and the other way to weld slower and cool- er. Further, when a welding engineer has determined that a part needs a 1⁄4- in. fillet weld, for example, using par- ticular voltage and WFS settings, syn- ergic controls enable parameter limits—operators can spin the knob all they want and they won’t weld out of spec. Further, to obtain good results, operators need only focus on GMAW- gun mechanics.
Quick Set
While called different names among systems and manufacturers, quick set and smart GMAW functions take per- formance beyond that of a synergic line. After engaging the quick-set func- tion, the wire feeder will automatically

select the optimal short-circuit fre- quency for the wire/gas combination used. The operator makes a short test weld, and in about 3 to 6 sec. the machine will automatically fine-tune performance. The operator will actually hear the arc as it adjusts to that perfect “sizzling-bacon” sound of the short- circuit GMAW process, with spatter minimized.
Quick set provides smart control. Regardless of the wire type and gas combination used, the control auto- matically fine-tunes the arc without any need for programming. To weld hotter or colder, the operator simply adjusts a single knob, typically the WFS- control knob. Quick set ensures that all parameters will automatically track. On some systems, the operator may have the option to adjust trim (which is really voltage), to flatten a high crown or otherwise adjust bead profile. Because advanced systems also have memory functions, the operator can store and recall these settings. MF
