                                                  Applicator Equipment

                                                  Obtaining maximum benefit from a Fusion brazing or soldering alloy depends, in part, on fast, error-free application. The size and location of paste deposits can play a vital role in controlling costs, while insuring consistent joint quality. Fusion offers a range of applicators to achieve repeat accuracy, plus quick adjustment for varied part styles and sizes. Each includes an adjustable control panel, a pressurized paste reservoir, and a specially designed applicator gun.

                                                  Model 710 Applicator Controller

                                                  Key to the efficient use of Fusion paste alloys is the Model 710 Applicator Controller, which provides for fast and accurate deposition of paste to joints of virtually any size and shape.

                                                  Pneumatically and electrically operated, the basic control panel is accompanied by an FE-71 applicator gun and a reservoir. (Gun, Reservoir, and Stand sold separately)

                                                  Paste, stored in the pressurized reservoir, is fed to the applicator gun through the nozzle, and onto the parts in deposit sizes ranging from small to dots to continuous stripes.

                                                  Gun(s) can be hand-held or integrated into an automatic machine and controlled via PLC.

                                                  Fig I — Compressed air from control panel is introduced to upper gun body, forcing circular piston and attached piston rod upward against coil spring. Pressurized paste alloy (from reservoir) fills vacant space between piston rod tip and nozzle orifice.

                                                  Fig. II — As timer de-energizes, compressed air is exhausted, and coil spring returns piston and rod to closed position. Piston rod tip displaces paste alloy through nozzle orifice and seals opening until next cycle. Precise deposit size is obtained by adjusting control panel timer, paste pressure, and length of piston rod stroke.

                                                  Satellite Paste Applicators are designed to complement an existing heat source, such as furnace or induction. These freestanding units apply single, multiple, or “ring shape” paste deposits onto assemblies. Cycling is automatic and error-free with an operator removing the pasted part and loading it into the adjoining heat source.

                                                  Applicator guns can also be mounted to a robot to apply a detailed combination of paste dots and stripes to a particular part. After the pasting cycle, the part is joined to its companion members and fixtured to the subsequent heating and cooling sequence.


                                                  Dual station system utilizes rotating mandrel technique to apply 360° stripe of Fusion Paste onto part joint area:

                                                  The R-100 Reservoir is recommended for applications where fast refilling and visual monitoring of the paste alloy level is desired. In production, the R-100 permits nearly 200 oz. of paste to be dispensed without interruption. Paste is packaged in special jars which incorporate a thin “follower” at the bottom.
