Product InformationModel ALC-701 Arc Length Control • Microprocessor Control • DC or AC Applications • GTAW (TIG) or Plasma • Large weight capacity • Precision voltage control Model 9790 Microprocessor Arc Length Control ALC-701 Arc Length Control Used with either GTAW (TIG) or Plasma (PAW) welding, the Jetline Arc Length Control maintains a constant preset arc length via control of the arc voltage. Arc Length Controls yield the following benefits: • Maintain constant weld penetration on uneven surfaces. • Regulation of welding voltage for precise, repeatable procedures. • Easy setup between different parts. • Minimum requirements for operator intervention. • Higher weld travel speeds. • Compensation for electrode erosion. • Automatic setting of the starting arc gap. How does it work? The arc length control measures arc voltage and compares the samples to the operator setting. To maintain the set arc length, the control works with a field proven servo drive to move the torch up or down as required. The arc length control works with (GTAW) TIG and Plasma power sources, either inverter or conventional, in DC, straight and reverse polarity or with AC welding currents. The arc length control is equally accurate and stable in pulsed or non-pulsed current mode. A simple remote cable interface is all that is required. The ALC-701 offers the widest range of features and benefits of any control in its class. 9790 Control - The Brains Using a microprocessor, proven for its use in the welding environment, the 9790 control yields superior performance. Jetline's experience in the design of this type of control for arc welding applications provides the latest and best control of arc length. Some of the key benefits include: • Backlit graphic LCD display for convenient reading and setup regardless of shop lighting conditions. • The LCD displays four lines of information. • Intuitive arrows rather than a lot of dials and switches allow you to input and change settings and parameters. • The polycarbonate overlay includes integral "touch pads" in place of conventional push buttons. • Electrical touch retract (the electrode touches the work and then retracts) allows the starting arc gap to be automatically preset for every weld - the operator has no need for feeler gauges or to view the distance. • Once the touch retract sequence has set the length, the actual arc length regulation can be delayed for up to 99 seconds as the power source, pre-purge arc initiation circuit, upslope, wire feed and oscillation take place. 15 Goodyear St, Irvine, California, 92618 U.S.A. • Tel: (949) 951-1515 • Fax:

The 9790 control is enclosed in a sealed industrial style steel cabinet. All connections are made with industrial grade Amphenol® plugs and sockets. The control is designed for easy panel mounting and can be located up to 75 ft. (23 m) from the actuator holding the welding torch. ALC-401-60D - The Brawn The ALC-401-60D actuator consists of a rugged servo driven motor slide built for years of continuous service. The ball screw design coupled with two hardened and ground shafts using recirculating ball bushings gives a maximum travel speed of 30 inches/min (750 mm/min). The entire mechanism is...

Fixtures In addition to its range of arc welding controls, Jetline designs and manufactures a superior family of fixturing products. These are used to hold and/or move the part to be welded or the welding torch and maintain their relative position. Jetline's fixturing includes: • Longitudinal Seamwelders Used for linear welding of sheets, cylinders, rectangles and cone sections. • Circumferential Welding Systems For circumferential welding of tanks and vessels, single or multi-torch applications. • Precision Welding Lathes For precision filters, valves and other small parts. • Side Beam Tracks...
