SAFETY PRECAUTIONS

WARNING

ELECTRIC SHOCK can kill.

•Do not touch electrically live parts such as output terminals or internal wiring.

•When inching with gun trigger, electrode and drive mechanism are “hot” to work and ground and could remain energized several seconds after the gun trigger is released.

•Turn OFF input power at welding power source before installation or changing drive roll and/or guide tubes.

•Welding power source must be connected to system ground per the National Electrical Code or any applicable local codes.

•Only qualified personnel should perform this installation.

Observe all additional Safety Guidelines detailed throughout this manual.

PRODUCT DESCRIPTION

The Power Feed Wire Feeders are high performance, digitally controlled, modular wire feeders. Properly equipped, they can support the GMAW, GMAW-P, FCAW, and SMAW processes. The Power Feed wire feeders are designed to be a part of a modular, multi process welding system.

The Power Feed Wire Feeders are 4 driven roll feed- ers that operate on 40VDC input power.

The Power Feed wire feeders are designed to be used with Power Feed compatible power sources, operating as a system. Each component in the system has special circuitry to “talk with” the other system components, so each component (power source, wire feeder, electrical accessories) knows what the other is doing at all times. This shared information lays the groundwork for a system with superior welding perfor- mance.

The Power Feed Wire Feeders are available config- ured in both boom and bench models. In addition, the Control Box and wire feed unit can also be purchased separately. The bench model is designed so that it can easily be converted to a boom feeder.

RECOMMENDED PROCESSES AND EQUIPMENT

RECOMMENDED PROCESSES

The Power Feed Wire Feeders can be set up in a number of configurations. It is designed to be used for GMAW, GMAW-P, FCAW, and SMAW for a variety of materials, including mild steel, stainless steel, and cored wires.

RECOMMENDED EQUIPMENT

The Power Feed Wire Feeders must be used with power sources having digital communication capabili- ties and 40 VDC auxiliary power. The presently avail- able power source is the PowerWave 455.

DUTY CYCLE

The Power Feed Wire Feeders are capable of welding at a 100% duty cycle (continuous welding). The power source will be the limiting factor in determining system duty cycle capability.

CONTROL BOX OPERATION

The most frequently used Control Box controls and settings are external; some features are accessed by internal controls and settings.

CONTROL BOX PANELS - UPPER PANEL

CONTROL/DISPLAY PANEL: (REQUIRED)

Each Power Feed Control box must have a Control/Display (CD) panel. This panel consists of adjustment knobs, digital displays and a series of indicator lights (LEDs). There are two knobs; each has a 4 digit LED display and a pair of LEDs associat- ed with it. Knobs and displays have dual functions; the LEDs indicate which function at any given time. This panel also has a dual color Status LED, used to indicate the general health status of the Control Box and its connection to other components in the system (power source, wire drive, etc.).

The left knob/display is labeled WFS / AMPS (wire feed speed/amps). In non-synergic modes, the WFS control changes the wire feed speed according to the desired procedure. In synergic welding modes (syner- gic CV, pulse GMAW) WFS is the dominant control parameter, controlling all other variables.
