pipe up to an unlimited size, including flat plate.
It is primarily designed for field use where
exceptional weld quality and consistent results
are required.
The Model 15 features rotation, wire feed, automatic voltage
control, cross-seam steering and torch oscillation. It is
available in many standard configurations, and can be
retro-fitted or customized with numerous application-specific
accessories to accommodate almost every need.
