The ARC Series Welding & Gouging Solution

2026-01-30

Unmatched Versatility: One Machine, Multiple Processes

Whether you’re engaged in manual metal arc (MMA) welding, carbon arc gouging, or lift tig welding, the ARC series is built to excel. With dedicated modes for Gouging, MMA, and LIFT TIG, these machines eliminate the need for multiple dedicated units, saving time, cost, and workspace. Perfect for workshops, shipyards, pipeline projects, and structural steel fabrication, they ensure seamless switching between processes without compromising performance.

Advanced Technology for Superior Performance

At the heart of the ARC series lies our proprietary full-bridge inverter soft switch control technology, combined with double IGBT modules and a quick recovery diode module. This integration ensures stable arc characteristics, high efficiency, and reduced harmonic interference, resulting in smoother welds, precise gouging, and lower power consumption.

Key Features Include:

Arc Force & Hot Start Adjustable: Fine-tune your arc for optimal penetration and easy ignition, even with challenging electrodes.
Anti-Stick Function: Prevents electrode sticking for smoother operation and less wasted material.
VRD (Voltage Reduction Device) ON/OFF: Enhances safety in risky environments by reducing no-load voltage.
Wired Remote ON/OFF: Allows convenient control from a distance, improving operational flexibility.
Extended Cable Capacity: Supports welding cables up to 100 meterswithout significant power loss.
Comprehensive Protection: Built-in safeguards against undervoltage, overvoltage, and overcurrentconditions, ensuring long-term component reliability.
Robust Insulation: Multiple insulation materials protect the PCB and main circuit from dust, moisture, and impact.

Ideal for

Heavy steel fabrication
Pipeline welding and repair
Shipbuilding and offshore operations
Construction and infrastructure projects
Maintenance and repair operations (MRO)

The ARC-1000 and ARC-1250 represent the next step in welding and gouging technology—combining power, precision, and protection in one robust package. For professionals who refuse to compromise, these machines deliver the performance and reliability needed to tackle the toughest jobs day after day.
