Matweld Inverter Welder 120A + Kit

The Matweld 120A Inverter Kit is an entry-level, highly portable DC arc welder designed for DIY enthusiasts, hobbyists, and light-duty maintenance. Despite its small footprint, it uses advanced IGBT technology to provide a stable arc and is often sold as a complete "starter setup," making it one of the most accessible welding options in South Africa.

Technical Specifications

• Model Codes: MAT9006LE (Standard Kit) / MAT9300BF (Mini Version).
• Input Voltage: Single Phase 220V/230V.
• Amperage Range: 20A – 120A.
• Duty Cycle: 60% at 120A (Rated at 40°C).
• Electrode Capacity: 1.6mm up to 3.2mm (Ideal for 2.0mm and 2.5mm rods).
• Weight: ~4.7kg (Extremely lightweight).
• Protection Class: IP21S.

Kit Contents (Scope of Delivery)

Depending on the specific SKU (MAT9006LE is the most common), the kit typically includes:

• 1 x 120A Inverter Welder.
• 1 x Electrode Holder with cable and Dinse connectors.
• 1 x Earth Clamp with cable and Dinse connectors.
• 1 x Auto-Darkening Welding Helmet (Note: Some kits include a basic handheld shield instead—always check the specific pack).
• 1 x Wire Brush & Chipping Hammer combo tool.
• Carry Strap: For easy over-the-shoulder transport while working on ladders or rooftops.

Key Performance Features

• IGBT Inverter Technology: Offers superior energy efficiency and a smoother arc compared to traditional transformer welders, reducing spatter and clean-up time.
• Digital Display: (On MAT9006LE models) Allows for precise amperage adjustments, which is vital when switching between thin sheet metal and thicker plate.
• Hot Start & Arc Force: Built-in features that assist in striking the arc and prevent the electrode from sticking to the workpiece during the weld.
• Portability: Designed to be moved easily around a home workshop or farm. It can be powered by most standard 15A household wall sockets.
• Dual Process: Suitable for both MMA (Stick) and Scratch-Start TIG welding (TIG torch and gas sold separately).

Common Applications

• Home DIY: Building burglar bars, security gates, and garden furniture.
• Automotive: Light repairs to exhausts, brackets, and trailers.
• Agriculture: Quick on-site repairs to wire fencing, cages, and lightweight agricultural implements.
• Maintenance: Ideal for plumbing or electrical contractors who need a small welder for bracketry and support structures.

Usage & Maintenance Tips

• Electrode Selection: While rated up to 3.2mm, this machine performs best with 2.0mm and 2.5mm electrodes (like Matweld M001/6013). Using 3.2mm rods for extended periods may push the machine to its thermal limits more quickly.
• Extension Leads: If you must use an extension lead, ensure it is a heavy-duty 2.5mm² cable and fully uncoiled to avoid voltage drops that can cause the arc to stutter.
• Safety First: If your kit includes the auto-darkening helmet, ensure the protective film is removed from the lens before use and test the "darkening" function by striking a spark or looking at a bright light.
• Cleaning: Periodically use a can of compressed air to blow out dust from the internal vents. Dust buildup is the primary cause of overheating in small inverters.
