T
he preferred electrode diameter depends on the application.
A
s a guideline, use the following rule of thumb:
Solid Wire Electrode (Super Arc L-56)
• 0.035” (0.9 mm) diameter for 14 gauge ( 2.0 mm) and
12 gauge (2.4 mm)
• 0.045” & 0.052” (1.1-1.3 mm) diameter for 10 gauge (3.2 mm)
and thicker.
M
etal Core Wire (Metalshield MC-6)
• 0.045” (1.1 mm) diameter for 14 gauge (2.0 mm); minimal
heat input and good puddle control.
• 0.052” (1.3 mm) diameter for 12 gauge (2.4 mm).
• 1/16” (1.6 mm) diameter for 10 gauge (3.2 mm) and thicker;
increases edge wetting and improves fit-up tolerance.
• Metal Core can make smaller weld beads, especially on
10 gauge (3.2 mm) and thinner base materials that tend to be
over welded with solid wire electrode.

hat acts as a fine tune adjustment of the arc. Similar to
conventional pulse programs, an increase in wave control will
results in a higher frequency and a more focused arc plasma.
The results will be especially noticeable in the metal core rapid
a
rc programs. Increasing wave control will improve welding
performance in robotic applications.
