Distance from the MIG torch nozzle to the work piece
The electrode wire stick out from the MIG torch nozzle should be
between 10mm to 20mm. This distance may vary depending on
the type of joint that is being welded.
MIG Welding (GMAW) Variables
Most of the welding done by all processes is on carbon steel. The
items below describe the welding variables in short-arc welding
of 24gauge (0.024”, 0.6mm) to ¼” (6.4mm) mild sheet or plate.
The applied techniques and end results in the GMAW process are
controlled by these variables.
Preselected Variables
Preselected variables depend upon the type of material being
welded, the thickness of the material, the welding position, the
deposition rate and the mechanical properties.
These variables are:
• Type of electrode wire
• Size of electrode wire
• Type of gas
• Gas flow rate
Primary Adjustable Variables
These control the process after preselected variables have been
found. They control the penetration, bead width, bead height, arc
stability, deposition rate and weld soundness.
They are:
• Arc Voltage
• Welding current (wire feed speed)
• Travel speed
