Description
The P280 is a single phase welding control. It utilises the latest in Large Scale Integration (LSI) digital circuitry. The heart of the P280 is a Motorola Micro Controller, running at an operating speed of four million cycles per second. The Micro Controller is capable of thousands of decisions in a fraction of a second.
Power Line Monitoring is a special feature designed into the software of the P280 Control. The software constantly monitors the incoming voltage level to allow itself time to respond to variations that could cause problems. The P280 has circuitry to constantly search phase shift variations. The Power Supply Input Output (PSIO) board can be observed for line drops, spikes, or noise. This gives the customer tools to prepare for future electrical problems.
This SCR fired system is housed in a 16 gauge steel cabinet and includes the PT4OO firing board, SCR Pack, Step-down transformer, and line board. The dimensions of the assembly are 16" wide, 14" high, and 6 3/4" deep.
