SKU: 6-100111
Availability: InStock

Description

Designed for demanding industrial work, the Pinnacle SELECTARC 405 Dual Voltage is an advanced MMA (ARC) welding machine packing serious performance into a digitally controlled IGBT inverter package. With automatic dual-voltage compatibility (380 V / 525 V), this heavy-duty unit adapts seamlessly to differing power supplies, offering reliability and flexibility on-site or in workshops alike.

Equipped with auto-select voltage, adjustable arc force, and hot‑start functionality, this machine delivers improved arc stability and penetration—especially useful for electrodes between 2.5 mm and 5.0 mm. A digital display provides real-time feedback on amperage and voltage, making setup and adjustments precise and efficient.

Safety features such as VRD (Voltage Reduction Device) protect both the operator and the machine during idle periods. Built to withstand industrial environments, the SELECTARC 405 supports welding on carbon steel, stainless steel, copper, and alloy steel electrodes with excellent reliability.
