Product Information COLD WIRE FEEDERS Microprocessor Control Four-Drive Rolls Optional Pulsed Feed Wire Guide Positioner Standard or Precision Drive Wide Range of Accessories Introduction Jetline cold wire feeders are primarily used for gas tungsten arc welding (TIG) and plasma arc welding (PAW). They can also be used in other applications where a controlled feed of wire is required such as a brazing operation. Cold wire feeding is used in the welding process for four purposes: 1 To add "fill" to a weld joint. The wire is used to fill a chamfered weld preparation or to add reinforcement for a butt weld. To enhance or preserve the metallurgical integrity of the weld metal by selecting the wire type to add the required elements to the weld or to replace those which are lost as a result of the welding operation. To control the weld pool by the chilling action of the wire, especially in out-of-position weld applications. The chilling effect reduces the weld pool size for easier control. To provide the fill for an overlay or cladding operation. The wire can be selected to provide the desired properties for the application. All Jetline wire feeders are suitable for any of the above applications. The standard CWF-50 is competitively priced and provides smooth, consistent wire feed for almost all types of welding wire, both hard and soft. The CWF-20C precision model is available for demanding applications where wire feed speed accuracy is critical. CWF-50 Cold Wire Feeder Typical mounting on a longitudinal seamer Description A Jetline cold wire feeder consists of the following elements: • • • Wire Feedhead and spool holder 9629 Microprocessor Controller WGP-1 Wire Guide Positioner Assembly Optional items are available including: • • • • • Pulsed Wire Feed Wire Feed Accessory Kits Protective Spool Cover Motorized Wire Guide Positioner Compact Wire Guide Positioner Speed Accuracy The CWF-50 uses a wire drive mechanism providing a speed holding accuracy of +1% of the rated speed. The CWF-20C is a high accuracy cold wire feeder which uses a precision motor with integrated tachgenerator and a precision drive control to provide speed holding accuracies of +0.1% of the rated speed. Both models come with integrated tach generators to allow the feeder to be operated under closedloop control for greater speed holding accuracy. 15 Goodyear St, Irvine, California, 92618 U.S.A. • Tel: (949) 951-1515 • Fax: (949) 951-9237

COLD WIRE FEEDERS Wire Feedhead and Spoolholder • Setting of wire feed speed • Setting of wire start delay time • Setting of wire stop delay time • Wire retract time Set-up Mode In this mode of operation, it is possible to set up various features of the control, including: The wire feedhead and the spoolholder are mounted on a common base to permit a smooth transfer of the wire from the spool, through the feed rolls, to the wire feed conduit. The feedhead should be mounted as close as possible to the welding torch. Brackets are available for this purpose, if required. The unit incorporates a...

COLD WIRE FEEDERS Wire Guide Positioner Optional Accessories The WGP-1 wire guide positioner is supplied as standard with all Jetline cold wire feeders. The unit fits easily on almost any torch for gas tungsten or plasma arc welding and incorporates three axes of adjustment. The horizontal and vertical axes are manually adjustable while welding to optimize the wire entry position into the weld pool. Model 607B Wire Spool Cover This is a transparent cover designed to protect the wire from the dust and dirt of the workshop. Pulsed Wire Feed This feature provides the ability to pulse the wire feed...
