Reduce Wire Feeding Issues - New patent pending Wire Monitoring Software automatically detects feeding issues and stops the wirefeed system before birdnests occur.

Aluminum Pulse Hot Start™ automatically provides more arc power to eliminate a "cold start" that is inherent with aluminum starts.

Built-in pulsed MIG programs- The easy to use digital interface makes it simple to recall any of the seven preset pulse programs.  All programmed information is restored after each power up.
