MEA-100B - AC Resistance Welding Power Supply
The MEA-100B - AC Resistance Welding Power Supply is perfectly suited for the precision resistance welding of small-sized components. This high performance AC resistance welding power supply capable of delivering up to 8,000 A output. It offers an intuitive user interface for easy operation, combined with a compact, desktop footprint.
Key features MEA-100B - AC Resistance Welding Power Supply
- Four weld control modes to enable single-cycle, half-cycle and multi-cycle welding
- The MEA-100B has a built-in weld monitor: upper and lower limits can be set to monitor the weld quality
- Secondary constant current control (multi-cycle welding) , offering secondary current feedback every half cycle ensures stable current flow.
- Stepper function: The stepper function increases or decreases the welding current when the weld count reaches a set value. This function is used to compensate for electrode wear or to accomodate increased temperatures within an electrode or work piece.
- Single-cycle welding: first half and second half waves may be programmed separately for small parts welding.
- Half-cycle welding: added precision with half cycle welding capability.
- Power supply voltage fluctuation compensation control, compensating current every half cycle in accordance with fluctuation of power supply voltage.
