Unitek Miyachi - Projection Welding - Miyachi - #2

Projection Welding System - Design and Operations

• Diagnostic controls monitor the power supply status and prevent weld firing if power levels differ from the desired set point. Digital control of charging and discharging produces rapid charging rates for decreased cycle times.

• Provides fast weld follow-up, allowing complete metal fusion without weld splatter. Electrode holders accept custom designed electrodes to your application. One-inch diameter (25.4 mm) electrodes as standard. Two-inch diameter (50.8 mm) electrodes are available as options on the KN Weld Head.

• All weld parameters are accessed, set, and displayed on front panel of the Pulsar weld controller.

• Two palm switches initiate the weld cycle (footswitch optional).

• Both the electrode approach pressure and speed are adjustable to guarantee safe handling and avoid damage to fragile parts. Solid state controller applies low pressure air to the air cylinder, closing the electrodes. Once electrodes are closed, high pressure air is released to the cylinder until the preset weld (forge) pressure is reached. Weld pressure, forge time, and hold time are adjustable over a wide range of settings. When the specified pressure is reached, the welding power supply is activated initiating weld pulse. Hold time is activated when weld pulse is fired.

• Rotation is initiated by automatic mode or manually with a standard footswitch. Optional single palm button is available.

• Pre- and post-weld station part sensors and head retract sensor verify part presence and head position, inhibiting rotation and welding if error condition exists. If pre-weld station senses missing part, that position will be skipped.
