This document covers both electric arc welding as well as gas welding and cutting. Any employees using compressed gases for welding should also read and be thoroughly familiar with the Standard Operating Procedures for Handling and Use of Compressed Gases at the PSFC. Safety Analysis: Introduction Gas metal arc welding (GMAW) is a welding process that has been commercially available for around 60 years. The basic operation of the GMAW process occurs when an electrical arc is established and maintained between a base material and a continuously feed wire electrode.

MMA welding consists of creating a high-intensity electric arc between a shielded metal-cored electrode and the metals to be joined. Oerlikon can provide a wide range of MMA welding power sources such as MINIARC and CITOARC. Install the inverter on a metal mounting plate. The mounting plate has to be unpainted and operative in all operating modes of the control equipment.

DO NOT use this machine unless you have been instructed. in its safe use and operation and have been given permission. PERSONAL PROTECTIVE EQUIPMENT. Safety glasses must be worn at all times in addition to welding mask. A welding mask with correct grade lens for GMAW must be worn. Oil free leather gloves and spats must be This video is an introduction to the Gas Metal Arc Welding (GMAW, MIG) process. It is designed to give a brief overview of the process and a short introduction for the beginner MIG welder to start Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals when cool result in a binding of the metals. It is a type of welding that uses a welding power supply to create an electric arc between a metal stick ("electrode") and the base material to melt the metals at the point of contact. Chapter 1 - Arc welding safety Introduction To achieve safe working conditions in the metal fabrication and welding industry, all personnel should be able to recognise the hazards which apply to their particular occupation. Welding operators must also know the correct operating procedures for the equipment. Chapter 10 Set U
