Katsu Arc Welding Machine – 315 Amp (Stick/MMA) - BX1-315

Industrial MMA Welding Machine 315 Amp

The Katsu BX1-315 is an indispensable power source for reliable metal fabrication, delivering consistent transformer power for demanding industrial and workshop environments. Operating on a 1-Phase AC 220V supply, this traditional Manual Metal Arc (MMA) welder relies on a highly durable internal architecture to ensure stable performance. It generates a massive 315 Amp maximum output, ensuring deep weld penetration and a consistently stable arc when joining thick structural steel. To guarantee versatility across diverse projects, operators can easily fine-tune the current anywhere between 60A and 315A, allowing for the flawless utilization of electrodes ranging from 1.6 mm up to 5.0 mm.

Productivity in professional workshops relies heavily on equipment endurance, and this machine is specifically engineered to perform without overheating. It boasts an exceptional 100% duty cycle at 186A for continuous, non-stop welding, and safely maintains a 35% duty cycle at its peak 315A capacity for high-intensity joining tasks. The internal circuitry is protected by professional Class F insulation and an IP21S-rated metal enclosure, actively shielding the core from workshop debris and extreme thermal stress. Grounded by a solid 80 kg static weight, the Katsu BX1-315 delivers highly reliable, heavy-duty performance for everyday industrial fabrication needs.

Key Features & Benefits:

• Broad Amperage Control: Features an intuitive, smooth adjustment mechanism allowing welders to dial in the exact current from 60A to 315A to match specific material thicknesses perfectly.
• High Electrode Compatibility: The strong, consistent arc easily burns through a wide variety of standard electrodes measuring between 1.6 mm and 5 mm, making it ideal for both fine repairs and heavy structural work.
• Optimized Industrial Duty Cycles: Engineered to keep production moving, offering continuous welding at 186A (100%) while reserving massive power (315A at 35%) for the toughest industrial joints.
• Superior Thermal Defense: Rated with Class F insulation, ensuring the internal copper and wiring can safely withstand intense operational heat without degrading over time.
• Rugged Workshop Protection: Housed in a rigid 80 kg metal chassis with an IP21S protection grade, safeguarding the machine against falling debris, tools, and harsh environmental conditions.
• Dependable Arc Stability: The high-performance AC output ensures the arc remains smooth and strictly focused, heavily reducing spatter and minimizing post-weld cleanup time.
