The Model 610 Applicator Controller is designed to dispense small deposits of paste brazing and soldering alloys or other viscous materials. Each paste deposit is precisely measured, ensuring controlled filler metal costs without waste.

Applicator Gun

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.

High temperature brazing is often associated with brazing in a furnace with an oxide-reducing atmosphere. Fusion offers a full line of high temperature brazing alloys for various base metals and filler metals. Common filler metals include copper and nickel based alloys.

Of all brazing processes, the most variables are presented when performing high temperature brazing in atmosphere or vacuum. Among these variables are the type of base and filler metal used, type of atmosphere, dew point, temperature, and even furnace construction. Most furnace brazing pastes are supplied without flux, consisting only of atomized filler metal and a neutral binder.

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.

Brazing aluminum with Fusion paste braze alloys has been popular since 1982. There are four basic challenges when brazing aluminum:

Brazing Alloys Melt Close to Melting Point of Base Metals
Aluminum Oxides Form Rapidly and Are Very Tenacious
Control of Heat During Joining
Obtaining the Correct Joint Clearance

Fusion has several paste alloys for brazing aluminum in open air, using conventional heating techniques and automated processes. Since the melting range of Fusion filler metals is very close to the base metals themselves, control of heat is most important. Both water washable and non corrosive flux formulations permit aluminum brazing of several commercially available aluminum base metals.

Silver brazing, sometimes known as a silver soldering or hard soldering, is brazing using a silver braze alloy based filler. These silver alloys consist of many different percentages of silver and other metals, such as copper, zinc, nickel and tin. General-purpose, lowest temperature with short melting ranges, they are versatile, easy to apply, having high strength. Fusion silver brazing alloys have excellent flow characteristics and mechanical properties. They have been used successfully for many decades on nearly all ferrous and non ferrous metals.

Solder paste is an alloy or unalloyed metal which, when heated, liquefies and melts to flow into the space between two close fitting parts, creating a soldered joint. Solder paste has suitable melting and flow properties to permit distribution by capillary attraction in properly prepared joints. Solder pastes produce joints that meet service requirements, such as strength and corrosion resistance. They also meet the specifications of the American Welding Society (AWS), The American Society for Testing Materials (ASTM), and in nearly all cases, ISO standards as well.

flux dispenser
dispens-a-flux brazing flux
Improve the performance of your brazing operation with Dispens-a-Flux Fusions line of dispensable flux for use with solid forms of filler metals.

Dispens-a-Flux is a homogeneous mixture that is non-separating, non-caking, and does not require constant heat and recirculation. These fluxes are specially formulated to be dispensed automatically through Fusion Applicator Systems, ensuring accurate, repeatable deposits.

Silver brazing, commonly referred to as silver soldering or hard soldering, is a brazing process that uses a silver braze alloy based filler paste. These silver brazing pastes are comprised of varying percentages of silver and other metals, such as copper, zinc, nickel and tin. These general-purpose pastes have the lowest temperature with short melting ranges. Their benefits include versatility, easy application, and high strength. Fusion silver brazing paste also offers excellent flow characteristics and mechanical properties. Fusion pastes have been time-tested on nearly all ferrous and non ferrous metals.

Of all brazing processes, the most variables are presented when brazing in atmosphere or vacuum. Among these are the type of base and filler metal used, type of atmosphere, dew point, temperature, and even furnace construction. Most furnace brazing pastes are supplied without flux, consisting only of atomized filler metal and a neutral binder.

Fusion offers a full line of controlled atmosphere brazing pastes for various base metals and filler metals. The filler metals include copper and nickel based alloys.

Traditionally, carbide to steel assemblies have been brazed with solid, shim-type filler metals and separate flux. Fusion has a better way for brazing carbide with paste filler metals. Brazing paste is a homogeneous blend of filler metal powder and a paste-like flux, which is dispensed in a single step and heated at rates of 100 500 parts per hour. Brazing temperatures can be achieved by both flame and induction heating methods.
Fusions paste for brazing carbide is designated STK-1260-650, a cadmium-free, silver bearing composition that meets the AWS (BAg 24) filler metal specification. STK has a fluxing range between 1000 1700F, is moderately restrictive, and stays active during extended heating cycles. Brazing carbide parts with paste yields tensile strengths equal to or greater than those joined with the shimflux method.

Fusion brazing pastes permit single-step application of filler metal and flux to metal assemblies. Brazing paste application can be handled by Fusion dispenser guns, either hand held or mounted on air cylinder slides. In either case, brazing paste application is fast, accurate and repeatable.

brazing paste deposits
Manual brazing paste application is accomplished with the pistol grip gun attachment, which is compatible with FE-71 applicator guns. These brazing paste applicators feature a comfortable grip handle and toggle action switch that permits easy application of paste deposits. Timed control enables consistent deposit sizes ranging from small dots to continuous stripes.
