Arc Welders

About this product High performance: 20–120 A welding current with 5-stage control allows for precise adjustment to thin sheets and profiles up to 3 mm thick. The wide working range covers spot welding, tack welding, and continuous welds, ensuring clean repairs on steel frames, fences, pipes, and sheet metal. The finely graduated current selection supports stable ignition and prevents burn-through in thin materials, which is particularly advantageous for bodywork, furniture frames, and lightweight metal constructions. IGBT inverter technology: The modern IGBT inverter efficiently converts energy, reduces material loss, and delivers a stable arc with minimal spatter. This results in smooth, even welds that are easy to grind and paint. The improved arc behavior makes it easier for beginners to use and ensures reproducible results for recurring tasks such as repair welding, assembly work on steel beams, or small metal projects around the house and workshop. Versatile compatibility: Uses common stick electrodes from 1.6 mm to 3.2 mm in diameter (1/16" to 1/8"), making it ideal for most DIY and repair tasks on structural steel. Features such as hot start for easy ignition, anti-stick to prevent electrode sticking, and a temperature protection system for reliable operation support consistent performance even during extended work sessions. This makes the device suitable for precise repairs, mounting brackets, and small construction and maintenance jobs. Lightweight and portable: The compact housing and low weight allow for one-handed carrying and quick relocation between the garage, workshop, and outdoor job site. The included fabric carrying case protects the device during transport and keeps accessories readily accessible. This means the device is quickly ready for use when you need to close a fence panel, weld a bracket, or patch a pipe on the go, saving time and travel for spontaneous repairs. Complete starter kit: The package includes 10 electrodes (2.5 mm diameter), a folding shield, a pair of gloves, a slag brush, and a 1.5 m grounding cable. This allows you to immediately tackle typical tasks such as repairing exhausts and frames, small equipment and machine repairs, assembling metal shelving, or attaching fittings. The coordinated accessories make initial welds easier and reduce the need for additional purchases. Key differences This model is specifically designed for 20–120 A, making it ideal for thin materials up to 3 mm thick, rather than very thick cross-sections. The IGBT inverter produces a smoother arc and less spatter compared to simple transformer-based devices, reducing the need for rework. Compatible with common electrodes (1.6–3.2 mm diameter), making it versatile for tack welding, spot welding, and short, everyday welds. Includes a fabric storage bag for easy storage instead of a bulky hard case, simplifying transport and storage. Complements starter kit: 10 x 2.5 mm electrodes, shielding gloves, brush, and grounding cable, allowing for immediate use without the need to purchase additional accessories. Includes a fabric storage bag for easy storage instead of a bulky hard case, making transport and storage easier.
