The flexibility ofchoosing from a variety of welding programs not onlyincreases productivity, but also promotes consistentlyhigh-quality welds. Power MIG 300, Invertec V350-PRO, and Power Wave welding systems are all WaveformControl Technology systems. They come fully loadedwith a software library that is accessible from theuser interface. With the Power Wave, software programming enables the flexibility of uploading theweld programs to a PC, or Ethernet and DeviceNetapplications (hard automation). The programs listed in the following tables weredeveloped by Lincoln Electric.* It is important to notethat, although we attempted to provide a broadoperating window for each program, they weredeveloped using Lincoln consumables. Therefore, Lincoln Electric cannot guarantee that theseprocedures will operate at optimum level when usedwith non-Lincoln Electric electrodes. A mode number is assigned to each weld program. The following lists include the most commonly usedweld programs, and are grouped according tomaterial. Find the mode number for your material andprogram specifications, then select that modenumber on the welding system user interface.

This waveform characterizes the weld output. Changingspecific values during specific periods of thewaveform directly affects the characteristics of theweld. Lincoln Waveform Control Technology WeldingSystems use high-speed electronics to monitor theelectrical signals from the welding arc and makeappropriate changes to the current waveform. All thedesired factors which control the welding arc from“arc start to arc stop” are written in software. Changes to the waveform can be made in real-time, (that is, during the weld), or after the weld if it is evident that the weld does not meet requirements. Arc Control: Controlling the Waveform Waveform Control Technology Welding Systems provide theoperators with a simple control knob, “Arc Control”, alsoknown as “Inductance” or “Wave Control”. It allows the operator to vary the arc characteristics from “soft” to “crisp” in most weld modes. It is adjustable from -10.0 to +10.0, with a nominal setting of 00.0. The following are descriptionsof the arc control functions for different weld processes. Arc Force - (SMAW) Range: -10 (soft) to +10 (crisp) Arc force adjusts the short circuit current for a soft arc, ora forceful driving arc, to prevent sticking and shorting ofelectrodes. Arc force is especially effective for the root pass on pipe with a stainless electrode, and helpsminimize spatter. Pinch - (GMAW CV) Range: -10 (soft) to +10 (crisp) Pinch controls the current applied at a short circuit duringshort arc welding. Frequency Modulation - (GMAW-PP) Range: -10 (low frequency) to +10 (high frequency) Frequency Modulation controls the spacing of the ripples inthe pulse-on-pulse weld. Low frequency modulation is usedfor slow travel speeds, while high frequency modulation isused for narrower ...
