Matweld Inverter Welder 230A 230V IND DIGI

The Matweld MAT9065 is a professional-grade, single-phase inverter welder engineered for demanding industrial environments. It is a dual-process machine, meaning it excels at both MMA (Stick) and Scratch-Start TIG welding. The "Digital" designation refers to its precise LED display, allowing for exact amperage control, which is critical when working with specialized electrodes like stainless steel or aluminum.

Technical Specifications

• Model Code: MAT9065.
• Input Voltage: Single Phase 220V/230V (50/60 Hz).
• Amperage Range: 20A – 230A (Infinitely adjustable).
• Duty Cycle: 60% at 230A (Capable of continuous welding for 6 minutes out of 10 at full power).
• No Load Voltage: 65V (Provides excellent arc striking).
• Electrode Capacity: 1.6mm up to 5.0mm.
• Weight: Approximately 6.95 kg (Highly portable for site work).
• Protection Class: IP21S (Protected against condensation and vertical water drops).

Key Performance Features

• Digital Display: Provides a real-time, accurate readout of the output current, ensuring repeatability for professional weld procedures.
• Hot Start MMA: Automatically boosts the current at the moment of arc ignition. This prevents the electrode from sticking to the cold workpiece and ensures a clean start every time.
• Built-in Protection: Features integrated sensors for Over-Voltage, Over-Current, and Thermal Overload. If the machine exceeds its duty cycle or encounters a power surge, it will safely shut down to prevent internal damage.
• Stable Arc Technology: Advanced inverter circuitry compensates for fluctuations in input power, maintaining a smooth, "buttery" arc even when used with long extension leads.
• Large Dinse Connectors: Uses the 35–50mm size connectors, which are larger and more robust than those on DIY machines, allowing for better current transfer and less heat buildup at the terminals.

Common Applications

• Heavy Steel Construction: Capable of running 4.0mm and 5.0mm 7018 low-hydrogen rods for structural beams and plates.
• On-Site Repairs: Its light weight makes it ideal for working on high-rise structures, farm implements in the field, or industrial plant maintenance.
• Precision TIG Work: Suitable for scratch-start TIG welding on stainless steel or mild steel pipes and brackets (requires a separate TIG torch and gas supply).
• Hardfacing: Provides the high current required to run Matweld M008 (Hardfacing) electrodes on earthmoving equipment.

Operational Tips

• Power Supply: For maximum performance at 230A, ensure the machine is plugged into a high-current industrial socket. Using a standard 15A household plug may trip the circuit breaker if you are running large electrodes at high power.
• TIG Setup: To use the TIG function, you will need a WP-17V (Valve type) TIG Torch and a cylinder of Argon gas. Remember that this is a DC-only machine, so it is not suitable for TIG welding Aluminum (which requires AC).
• Cable Care: The MAT9065 is supplied with heavy-duty cables. Ensure the earth clamp is attached to a clean, unpainted surface of the workpiece to maintain arc stability.
• Cooling: After a heavy welding session, leave the machine switched on for a few minutes before turning it off. This allows the internal fan to continue cooling the sensitive electronics.
