INTRODUCTION AND DESCRIPTION
2.1
GENERAL
This manual is intended to be a guide to the understanding of the 200AP welding
machine and process requirements. The application outlined is typical and serves only to
illustrate and explain the relationship of power source to the process. Selecting the correct
power source depends upon process requirements.
This manual will concentrate only on safety and the operational aspects of the welding
power source.

WELDING MACHINE DESCRIPTION
The SanRex model 200AP is an inverter based DC Power Source Unit that is powered
from an external source of 208~230/460 VAC, single or three phase power. The 200AP
models is capable of providing Constant Current (CC) output characteristics. The 200AP is
also equipped with a lift arc starter for use with Gas Tungsten Arc Welding (GTAW) as well
as user settable Hot Start and Arc Control functions for use with Shielded Metal Arc Welding
(SMAW) process. The unit is equipped with a digital Amperage/Voltage meter and Output
Contactor and Output Control functions that that are conveniently located on the front control
panel. The 200AP incorporate high-performance microcontroller to achieve complete digital
control and is designed with a flame and impact resistant non-conductive plastic case
enclosure.
