EZITIG 180
In general, electrodes that have an appropriate in-
cluded angle and a suitable flat on the tip, exhibit the
following benefits:
• Last longer
• Have better weld penetration
• Have a narrower arc shape
• Can handle more amperage without eroding.
Sharper electrodes with smaller included angle provide:
• Offer less arc weld
• Have a wider arc
• Have a more consistent arc
The included angle determines weld bead shape and
size. Generally, as the included angle increases, pen-
etration increases and bead width decreases.
