Page 11: Chapter 1: Description
Section I: Features Features The Dual EZ-Air Kit, herein called EZ-Air, is an accessory for weld heads that pneumatically controls the actuation of the electrodes and maintains the preset firing force. At a predetermined firing force the EZ- Air closes the inlet and outlet valves to the weld head actuation cylinder and eliminates over-force. EZ- Air operates from power supply-generated power and has the following features: •... -
