Construction and Performance Verification of Single Phase Welding Machine Saving Energy Controlled by Solid State Relay

Abstract

This study aims to construct and find out the efficiency of single phase welding machine saving energy controlled by solid state relay. In order to find out the efficiency of the machine, we need to compare power consumption ratio to electrical welding machine (coil slider single phase) and evaluate the welders’ satisfaction.

        The study was carried out with 10 welders from different welding shops in Suratthani. The machine was used eight hours per day, (four hours for welding and four hours for preparing welding materials)

        The main findings are as follows : The power consumption was 0 (Zero)kilowatt/ 4hour while preparing welding materials. The power consumption was 178.20 kilowatt/4 hour while welding. Each machine can save energy 27.72 kilowatt/day. The level of subjects’ satisfaction with the machine, creative thinking, durability, design and application were acceptable.

        The result of the satisfaction of users of single phase welding machine saving energy controlled by solid state relay. At the highest level
