W1006313 - Thermal Arc 141 AC/DC TIG Welder System with Foot Pedal

Professional Aluminum Welding at Home

The Thermal Arc ArcMaster 141 AC/DC is a game-changer for the home hobbyist, DIY fabricator, and light maintenance professional. Traditionally, welding aluminum required large, expensive, and power-hungry machines. The ArcMaster 141 changes the landscape by packing full AC/DC TIG capabilities into a portable unit that runs off a standard 120V household outlet. This means you can tackle aluminum intake manifolds, brackets, and custom fabrication projects right in your garage without needing expensive electrical rewiring.

This complete system (SKU: W1006313) comes ready to weld with everything you need to get started, including a high-quality foot pedal for precise heat control—a critical feature when welding aluminum. The machine features both High Frequency (HF) start for clean, non-contact arc initiation and Lift TIG for sensitive electronic environments. Beyond TIG, it is also a capable Stick welder, allowing you to switch to coated electrodes for outdoor repairs on steel gates, trailers, and fences where gas shielding isn't practical.
