ROCKER ARM WELDERS

Spot Weld’s Rocker Rite Type Resistance Welder is widely used by the metalworking industries today because of its extreme versatility. This general purpose machine represents a new high achievement in welder design and engineering, and embodies advantages which afford the greatest performance. Its modern design has incorporated ruggedness, accuracy, and reliable uninterrupted performance – all of which are of the utmost importance to high production runs.

The Rocker Rite Rocker Arm Welder is available in a standard range of throat depths, electrode forces and transformer capacities.

General Construction

The main frame is high quality welded steel construction styled for trim appearance and functional design. The slim design requires a minimum of floor space. The upper arm extension is built integrally with the frame. The removable rear cover permits ready access to the frame interior for inspection and maintenance.

Methods of Operation

Transformer
The "heart of the welder" the Rocker Rite transformer is built to RWMA automotive and appliance standards. Transformer secondaries are of cast copper with integral, non-corrosive water cooling pipes. Class ‘F’ insulation is used throughout. The transformer is bonded and sealed with high temperature varnish baked on each coil. The resulting unit is a high power factor, high efficiency transformer with low leakage reactance.

Secondary Circuit
Flexible copper leads are provided between the upper transformer lead adapter and the movable upper horn and die. Lower conductor is also made of a flexible copper lead to the lower arm assembly.

Supply Voltage and Frequency
The Rocker Rite type machine can be supplied for any one standard voltage supply of 220, 380, 440, or 550 volts, 50 or 60 cycles, single phase. Dual voltage, special voltage or frequency are available as extras.

Silver Plating
To insure proper contact and maximum power efficiency, all stationary contacts on the Rocker Rite machines are silver plated. This feature has proven by past performances to surpass other methods of obtaining an efficient, long life bond between two current carrying members.

Air Accessories
Standard Equipment included air pressure regulator, gauge, lubricator, speed control valve, and solenoid valve for control of the cylinder.

Electrical Accessories
Standard electrical accessories include a two stage foot switch. Dual palm buttons are available as options.

Controls
Standard NEMA controls are mounted to the right side of the welder frame unless special tooling or customer preference preludes. JIB electrical specifications can be included as an extra.

Optional Equipment

Adjustable, retractable, Cylinder
This type of cylinder incorporates the features of an adjustable stroke cylinder, plus a retraction feature. This permits opening of the electrodes to maximum stroke at any time to clear work pieces. With work pieces cleared, electrodes return to short normal operating stroke welding. Operation of the retraction stroke can be controlled by the foot switch.
