When these parameters are identical, the pulsing fre- quency will be the same, helping to stabilize the arcs. Every welding gun requires a separate shielding gas regulator for proper flow rate and shielding gas cover- age. Do not attempt to supply shielding gas for two or more guns from only one regulator . If an anti-spatter system is in use, each[...]

V OL T A GE SENSING The best arc performance occurs when the Power W ave has accurate data about the arc conditions. Depending upon the process, inductance within the electrode and work lead cables can influence the volt- age apparent at the terminals of the welder . V oltage sense leads improve the accuracy of the arc conditions and can have a dra[...]

WORK V OL T A GE SENSING The Power W ave is shipped from the factory with the work sense lead enabled. For processes requiring work voltage sensing, connect the (21) work voltage sense lead from the Power W ave to the work. Attach the sense lead to the work as close to the weld as practical. T o enable the work voltage sensing in the Power W ave, r[...]

GENERAL DESCRIPTION The Power W ave power source is designed to be a part of a modular , multi-process welding system. Depending on configuration, it can support constant current, constant voltage, Surface T ension Transfer and pulse welding modes. The Power W ave power source is designed to be used with the family of Power Feed wire feeders, opera[...]

RECOMMENDED PR OCESSES AND EQUIPMENT RECOMMENDED PROCESSES The Power W ave 455/R can be set up in a number of configurations, some requiring optional equipment or welding programs. Each machine is factory prepro- grammed with multiple welding procedures, typically including GMA W , GMAW -P , FCAW , GT A W and STT for a variety of materials, includi[...]

CASE FR ONT CONTROLS All operator controls and adjustments are located on the case front of the Power W ave. (See Figure B.1) 1. POWER SWITCH: Controls input power to the Power W ave. 2.

WELDING MODE DESCRIPTIONS CONST ANT V OL T A GE WELDING For each wire feed speed, a corresponding voltage is preprogrammed into the machine through special soft- ware at the factory . The preprogrammed voltage is the best average voltage for a given wire feed speed. With synergic programs, when the wire feed speed changes, the Power W ave will auto[...]

PULSE WELDING Pulse welding procedures are set by controlling an overall “ arc length ” variable. When pulse welding, the arc voltage is highly dependent upon the waveform. The peak current, background current, rise time, fall time and pulse frequency all affect the voltage. The exact voltage for a given wire feed speed can only be predicted wh[...]

STT WELDING The pictures illustrate the waveshape of current for the process. They are not drawn to scale, and are intend- ed only for the purpose of showing how the variables affect the waveform. T rim in the STT mode adjusts the tailout and back- ground portion of the waveform. T rim values greater than 1.0 add more energy to the weld and make th[...]

OUTPUT RECTIFIER, OUTPUT CHOKE AND STT CHOPPER BO ARD The output rectifier receives the AC output from the main transformer secondary and rectifies it to a DC voltage level. The output choke is in series with the negative leg of the output rectifier and also in series with the welding load. Due to the current "smoothing" capability of the[...]

THERMAL PR O TECTION Three normally closed (NC) thermostats protect the machine from excessive operating temperatures. These thermostats are wired in series and are con- nected to the control board. One of the thermostats is located on the heat sink of the output rectifier , one on the DC bus, and one on the output choke. Excessive temperatures may[...]

GENERAL DESCRIPTION OF THE STT (SURF A CE TENSION TRANSFER) PR OCESS The STT process cannot be classified as either a con- stant current (CC) or a constant voltage (CV) applica- tion. The STT function produces current of a desired waveform to reduce spatter and fumes. The STT process is optimized for short-circuit GMA W welding only . E-10 E-10 THE[...]
