CALABASAS, Calif. — To bring customers modern inverter welding technology at an accessible price point, Harbor Freight, America’s #1 tool retailer, has added the BERGER™ 3‑in‑1 135 Amp Multi‑Process Welder to its extensive lineup of welding products. Designed for home workshops, garages, and light fabrication environments, the new inverter‑based welder delivers versatile performance, precise control, and expansion capability in a compact, lightweight platform.
The BERGER 3-in-1 Welder supports Flux‑Cored (FCAW), Stick (SMAW), and DC‑TIG (GTAW DC) welding, giving customers multi-process flexibility while operating on standard 120V household power. By replacing traditional, transformer-style equipment with modern inverter architecture, the welder provides a smooth, stable arc and improved parameter control in a significantly smaller footprint.
Engineered for welding steel, stainless steel, and alloy steels, the BERGER 3-in-1 Welder delivers up to 135 amps of DC output and features independent voltage and amperage controls, allowing users to fine-tune weld bead appearance and maintain consistent arc characteristics across material types and thicknesses.
A large digital display enables clear, easy adjustments to welding parameters, improving setup accuracy and usability compared to legacy analog systems. Industry-standard 10mm DINSE connections support quick, secure swapping of torches and accessories while offering compatibility with standard welding equipment.
The optional BERGER TIG Welding Accessory Kit enables DC‑TIG welding when paired with the 3-in-1 Welder for cleaner weld profiles and greater control on thinner materials, allowing users to expand capabilities without replacing their equipment as their skills advance.
Weighing just 11 pounds, the BERGER 3-in-1 Welder features an ergonomic top handle for easy transport and storage. A durable metal enclosure supports long-term use in garage, workshop, and mobile repair environments, making it suitable for DIYers, hobbyists, and professionals alike.
The welder includes:
- 5-ft. flux‑cored gun
- 10-ft. stick electrode holder
- 10-ft. ground cable
The BERGER 3‑in‑1 Welder has been tested and certified by CSA Group to conform to applicable UL consumer safety standards, helping ensure safe operation and compliance with recognized requirements for welding equipment used in home shops and workshops. Third‑party testing and certification support consistent performance and reinforce Harbor Freight’s commitment to quality, reliability, and user safety.
This new launch expands Harbor Freight’s existing selection of welders, welding accessories, and safety equipment to bring customers a modern, inverter‑based multi‑process option designed for portability, versatility, and precise control. Whether learning foundational welding techniques or supporting ongoing fabrication projects, the BERGER 3‑in‑1 Welder delivers flexible capability at an accessible price point.
The BERGER 3‑in‑1 135 Amp Multi‑Process Welder and BERGER TIG Welding Accessory Kit are available now exclusively at Harbor Freight stores nationwide and HarborFreight.com.
