ALC CONTROL (Model 9690) ALC-401 Arc Length Control The ALC-401 offers the widest range of features and benefi ts of any control in its class. 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 benefi ts:
Maintain constant weld penetration on uneven surfaces.Օ Regulation of welding voltage for precise, repeatable procedures. Easy setup between different parts.Օ Minimum requirements for operator interven-tion. Higher weld travel speeds.Օ Compensation for electrode erosion.
Automatic setting of the starting arc gap. 9690 Control - The Brains Using an Intel ծ microprocessor, proven for its use in the welding environment, the 9690 control yields superior performance. Jetline's experience in the design of this type of control for arc welding appli-
cations provides the latest and best control of arc length. Some of the key benefi ts include: Backlit, 2-line LCD display for convenient reading and setup regardless of shop lighting conditions.Օ The LCD displays two lines of information. Each line provides 20 alphanumeric characters. Intuitive arrows rather than a lot of dials and switches allow you to input and change settings and parameters.Օ 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.Օ 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. 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 fi eld 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 conven-
tional, 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 cur-
rent mode. A simple remote cable interface is all that is required. 15 Goodyear St, Irvine, California, 92618 U.S.A. Tel: (949) 951-1515 Օ Fax: (949) 951-9237 size="-2">
