ME-35A Precision Welding AC Power Supply
The ME-35A is an AC resistancewelding control developed for the spot welding of precision parts. Oneof four control methods (primary or secondary constant current, power source,voltage fluctuation, or single cycle control) can be selected.
The built-in weld monitorcalculates and displays the current RMS value for every weld (High-lowcurrent limits can be monitored as well as conduction degrees). With theWelcard (RAM card), schedules can be input from one control to another.7 schedules can be stored in one file, and up to 13 files on one Welcard.The control also has many features that were carefully designed to maximizeuse with automated systems.
Features and Benefits
- 7 weld schedules, 2 solenoid valve outputs,and 5 steps
- 4 types of control: primary or secondaryconstant current, power voltage fluctuation compensation, or single cyclecontrol
- Schedules can be set using the WELCARD
- Built-in Weld Monitor
- Dual Pulse welds up to nine impulses
- External I/O signals allow use withautomated systems
- Clear, easy-to-read display and simplepanel operation
