Frequently Asked Questions

What makes the Typhoon 330 different from the PowerTIG series?
The Typhoon 330 offers significantly more waveform control, split-wave programming, independent AC amplitude adjustment, higher pulse frequencies, and Everlast's exclusive Trapezoid waveform for advanced aluminum welding.

Why are five AC waveforms beneficial?
Different waveforms allow the arc to be tailored for penetration, puddle control, cleaning action, heat input, and operator preference depending on the application.

What is Advanced AC Pulse?
Advanced AC Pulse blends AC with DC negative, increasing penetration while maintaining the cleaning action needed for aluminum welding.

Is this machine intended for beginners?
While the interface is designed to be intuitive, the Typhoon 330 is best suited for experienced welders and professionals who want complete control over the welding process.

Can I save welding programs?
Yes. The machine allows welding programs to be stored for repeat production work and faster setup.

Does it support both single-phase and three-phase power?
Yes. The Typhoon 330 operates on both 240V single-phase and 240V three-phase input power.
