Model CW-10 Semi-Automatic Contact Welding System The Model CW-10 is a semi-automatic contact welder which permits one operator to produce up to 1,200 movable contact arms per hour. The operator positions the contact arm in a custom fixture and initiates the automatic sequence with a two-hand anti-tie-down safety control. The contact is automatically positioned and welded. This machine can be ordered as either a tape contact or button contact welding system depending on the feed module specified.

The Model CW-10 is a semi-automatic contact welder which permits one operator to produce up to 1,200 movable contact arms per hour. The operator positions the contact arm in a custom fixture and initiates the automatic sequence with a two-hand, anti-tie-down safety control. The contact is automatically positioned and welded.

This machine can be ordered as either a tape contact welder or button contact welder, depending on the feed module specified:

Tape Feed Module automatically advances contact tape from a coil, cuts a contact segment to size and positions it on the arm for welding.

Typical contact tape cross-sections. Most tapes are composed of two or three metals or alloys permanently clad together. Only the top layer is precious metal. Base layer is patterned to facilitate welding. A wide variety of designs are available.

Button Feed Module is a vibratory bowl feeder combined with an escapement mechanism unit to position the contact arm.

Button contacts are available in almost any size, combination of metal and base configuration. Buttons may be plated with braze metal or solder for reflow brazing or soldering.

This machine is very efficient for short production runs with production rates approximately triple for those manual operations.

Electrical Contacts

All Welding & Automation, Inc. contact assembly and welding systems can be equipped to automatically handle either button contacts or contact tape. Button contacts are automatically fed from a vibratory bowl feeder and positioned on the contact arm by a pick-and-place device. Contact tape is a continuous strip of contact metal supplied in coils. Tape is fed from the coil and contact segments are automatically cut to size, positioned on the arm, welded in place and coined to precise shape and thickness. Welding & Automation, Inc. also provides machines that will blank and coin button contacts from continuous strips of contact tape at very high speeds.

Contact tape is often a more economical approach that preformed contacts. Material costs are often lower and, with the right equipment, tape handling is faster and easier than feeding and positioning individual contacts.

The Welding & Automation, Inc. Customer Service Welding Laboratory is experienced in evaluating both contact tapes and button contacts and can recommend the best selection for any specific application.
