GENERAL DESCRIPTION

The POWER WAVE 455 STT is a high performance, digitally controlled inverter welding power source capable of complex, high-speed waveform control. Properly equipped, it can support the GMAW, GMAW- P, FCAW, SMAW, GTAW, CAC-A and STT process- es.

RECOMMENDED PROCESSES AND EQUIPMENT

RECOMMENDED PROCESSES

The Power Wave can be set up in a number of config- urations, some requiring optional equipment. Each machine is factory preprogrammed with multiple weld- ing procedures, typically including GMAW, GMAW-P, FCAW, SMAW, GTAW and CAC-A, for a variety of materials, including mild steel, stainless steel, cored wires, and aluminum. Additionally, it supports the Surface Tension transfer process (STT) for mild steel and stainless steel.

RECOMMENDED EQUIPMENT

The POWER WAVE 455 STT must be used with the Power Feed family of wire feeders. These feeders are required to access and make use of the many of the welding features contained in the POWER WAVE 455 STT.

DESIGN FEATURES AND ADVANTAGES

A unique feature of the Power Wave is the ability to function without any controls, when used with Power Feed wire feeders. All power source control informa- tion comes to the Power Wave from a Power Feed wire feeder.

The following chart lists the power source parameters that can be changed from the Power Feed wire feed- er, and gives examples of each. (Optional equipment may be required to access some of the following para- meters.)

Parameter	Examples
Welding	Stick Crisp, Stick Soft, Flux Cored with Gas,
Mode	Flux Cored without Gas, CV, Synergic CV,
	.035 Stainless Pulse, .045 Steel Pulse, 5356

ADDITIONAL DESIGN FEATURES AND ADVANTAGES

•Designed to NEMA EW-1 and IEC 974-1 Standards.

•Qualifies for “S” mark on nameplate, which means it can be used in areas where there is increased risk of electric shock.

•Multiple process output ranges: 5 - 570 amps.

•Easy access for input connections. Connections are simple strip and clamp (no lugs required).

•F.A.N. (fan as needed). Cooling fan runs only when necessary.

•Modular construction for easy servicing.

•Thermostatically protected.

•Electronic over current protection.

•Input over voltage protection.

•Utilizes digital signal processing and microprocessor control.

•Simple, reliable input voltage change over.

•All system components communicate and transfer information.

•Auto device recognition simplifies accessory cable connections.
