BE SURE THAT ALL INSTALLATION, OPERATION, MAINTENANCE AND REPAIR PROCEDURES ARE PERFORMED ONLY BY QUALIFIED INDIVIDUALS.
ELECTRIC SHOCK can kill. 3.a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands.
WELDING SPARKS can cause fire or explosion. 6.a. Remove fire hazards from the welding area. If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjacent areas.

SYSTEM DESCRIPTION The POWER WAVE 355/405 and Power Feed 10/11 family of products utilize a digital communication sys- tem called Linc-Net. Simply put, Linc-Net allows large amounts of information to be passed at very high speeds between components (nodes) in the system. The system requires only two wires for communication, and because of its bus-like structure, the components may be connected to the network in any order, thus...
Basic Rules • Each group is required to have one user interface. No group may have more than one user interface. • Each group can have up to seven Feed Heads. Exception: Group 3 is limited to a maximum of six Feed Heads.
INSTALLATION Multiple Group System FIGURE A.3 No “FH0 Allowed! Single Group Multi-Head System FIGURE A.4 No “FH0 Allowed! The Dual Head option allows the ability to maintain 2 sets of procedures. If more then 2 heads are used, odd #’s use FH1 settings, even #’s use FH2 settings.

A-11 WELDING WITH MULTIPLE POWER WAVES CAUTION Special care must be taken when more than one Power Wave is welding simultaneously on a single part. Arc blow and arc interference may occur or be magnified. Each power source requires a work lead from the work stud to the welding fixture.

SAFETY PRECUATIONS Read this entire section of operating instructions before operating the machine. WARNING ELECTRIC SHOCK can kill. • Unless using cold feed feature, when feeding with gun trigger, the elec- trode and drive mechanism are always electrically energized and could remain energized several sec- onds after the welding ceases.
POWER WAVE 355/405 – Operation Semi Automatic Power Waves can only be used with Linc-Net compatible Power Feed semi-automatic wire feeders. In addition, the Power Feed semi-automatic wire feeders may require optional equipment to access certain weld modes in the Power Wave. Other models of Lincoln feeders, or any models of non-Lincoln wire feeders, cannot be used.
Power Waves encom- passes a wide range of common processes and will meet most needs. If a special welding program is desired, contact the local Lincoln Electric sales repre- sentative. To make a weld, the Power Wave needs to know the desired welding parameters.
In non-synergic modes, the WFS control behaves more like a conventional CV power source where WFS and voltage are independent adjustments. Therefore to maintain the arc characteristics, the operator must adjust the voltage to compensate for any changes made to the WFS. In constant current modes (stick, TIG) this control adjusts the output current, in amps.
TIG GTAW The TIG mode features continuous control from 5 to 425 amps. The TIG mode can be run in either the Touch Start TIG or Scratch start mode. The Arc Control level selects the starting mode. Between –10 and 0, the Touch Start TIG mode is selected.
PULSE WELDING (GMAW-P) The pulsed-arc process is, by definition, a spray trans- fer process wherein spray transfer occurs in pulses at regularly spaced intervals. In the time between pulses, the welding current is reduced and no metal transfer occurs. Pulsed-arc transfer is obtained by operating a power source between low and high current levels.
Since Arc Control varies weld droplet transfer rate, the Arc Control can be used to vary the ripple spacing in the weld bead. BENEFITS OF PULSE ON PULSE FROM LINCOLN ELECTRIC • Excellent appearance of the weld bead • Improved cleaning action • Reduced porosity Table B.2 shows WFS and Trim settings for common...

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 switch board, one is located on the output choke and the third thermostat is located on the DC Bus Board.
THEORY OF OPERATION INSULATED GATE BIPOLAR TRANSISTOR (IGBT) OPERATION An IGBT is a type of transistor. IGBT are semiconduc- tors well suited for high frequency switching and high current applications. Example A in Figure E.6 shows an IGBT in passive mode.
