1 Introduction
Gas Metal Arc Welding (G.M.A.W.) is an arc
welding process where a consumable wire is
fed by motor driven feed rolls to a welding
gun, and where welding current is supplied
from the welding power source. The welding
arc is struck between the work piece and
the end of the wire, which melts into the
weld pool. The arc and the weld pool are
both shielded by gas flow from the gun, or
in the case of “self shielded” wires, by gases
generated by the wire core.
The process is very versatile in that by selection
of the correct wire composition, diameter and
shielding gas, it can be used for applications
ranging from sheet-metal to heavy plate, and
metals ranging from carbon steel to aluminium
alloys.
The Weldmatic 215 has been designed to be
used with consumable wires in the range from
0.6mm to 1.2mm diameter. The smaller wire
sizes are used when welding at lower currents,
such as sheet-metal applications. Increasing the
wire diameter permits higher welding currents
to be selected.
A common application of G.M.A.W. is for
welding Mild Steel. In this application, a Mild
Steel solid consumable wire such as AUSTMIG
ES6 is used with a shielding gas of Carbon
Dioxide, or Argon mixed with Carbon Dioxide.
Alternatively, Flux-cored consumable wires are
available in both gas shielded, and ‘gasless’ self
shielding types.
Stainless steel and Aluminium can be welded
with G.M.A.W. using the correct consumable
wire and shielding gas.
The Weldmatic 215 wirefeeder has been
designed to feed a range of hard, soft, and
flux-cored wires for the G.M.A.W. process.
A compact motor with integral gear box is
coupled to a two roll drive assembly forming
the basic component of the wirefeeder. The
motor is controlled by an electronic speed
control which provides speed regulation and
compensation for supply voltage variations.
