Organization: NEMA
Publication Date: 1 January 1983
Status: active
Page Count: 51
scope:

This standards publication applies to wire feed systems used in semiautomatic arc welding processes such as gas-metal arc welding, flux-cored arc welding with gas, flux-cored arc welding without gas, submerged arc welding, and gas-tungsten arc welding with the addition of filler wire.

This publication does not apply to automatic arc welding systems or to gas-tungsten arc welding apparatus without the addition of filler wire.
