Based on the study on the analogously controlled power source for strip surfacing, a newmicrocrocomputer controlled automatic welding machine is developed for strip surfacing. The configurahon andworking principle of the machine is introduced and working principle of the machine is intreduced in thispaper. The experimental results show that the machine features its stable output voltage, wide rangs ofvoltage adjusrnent. Very strong conpensation ability of pewer source, reliable protection, and highautotnaticity. It meets the requirements Presented by the electro-slag surfacing (ESW) and the high speedsurfacing (HSW) and provides a good weld quality.
