- Multi-process welding versatility: This all-in-one welder supports MIG, Flux-Cored (FCAW), Stick, and TIG welding processes, giving you flexibility for a wide range of applications. Easily switch between processes to handle everything from auto body repair to fabrication and maintenance work using a single machine.
- Powerful 120v performance with wide output range: Operates on standard household 120V power while delivering a 30–140 amp output range for MIG and FCAW welding and 10–120 amps for TIG. Weld 24-gauge sheet metal up to 3/16" in a single pass and up to 1/4" steel using flux-cored wire for heavier-duty projects.
- Smooth arc & user-friendly operation: Engineered with a forgiving arc and minimal spatter, this welder ensures smoother starts and easier control, making it ideal for beginners and experienced welders alike. The intuitive interface and quick setup get you welding fast.
- Heavy-duty wire drive system: Features an adjustable drive system designed to reduce wire tangling and crushing. The cast aluminum gearbox provides increased torque and quiet operation, while the brass-to-brass gun connection enhances conductivity for consistent weld quality.
- TIG ready with auto-detection: Supports TIG welding (torch and pedal sold separately) with automatic detection and configuration when a foot pedal is connected, allowing precise control over weld output for thin materials and detailed work.
