Airco Introduces New Pulsed Welding Systems

— Literature Available Airco Welding Products has announced the introduction of the newest member of its family of Pulse Arc™ welding systems for pulsed spray transfer welding. The Pulse Arc 500 system, like the Pulse Arc 350 model, is designed around the pulsed spray process.

The process allows for spatter-free welding and excellent arc control in applications ranging from high deposition out-of-position welding on thick plate to smooth, low-distortion welding on thin gauge materials.

The Pulse Arc 500 system has the power to handle large diameter cored wires up to 3/32 inch and can pulse Metal-Cor® 6 wire for high deposition rates. The system also has exceptional smaller diameter performance characteris- tics. Like the Pulse Arc 350, the 500 model is a complete system consisting of a transistorized 500- ampere air-cooled or 550 ampere water-cooled gun. The fully integrated machine takes the normally complex engineering requirements of pulsed spray welding and translates them into a few simple pushbutton functions—at a price comparable to a standard MIG package.

The pushbuttons and toggle switches allow the operator to select among pulse, spray and dip transfer processes. He then presses the appropriate switches for the required wire diameter and shielding gas, and he's ready to go. A single knob on the remote pendant simultaneously sets welding current, voltage, wire feed speed, and pulse frequency. The advanced solid-state circuitry automatically controls all parameters.

The system is pre-programmed for stainless and mild steels, but other wires, such as silicon bronze and aluminum can be used by referring to the easy-to-read process selector charts. The Pulse Arc 500 system is well suited for plants where one machine is needed to perform several welding operations.
