The **SIP WELDMATE® PRO 120A DC TIG/ARC Inverter Welder** is a **dual process professional welder** designed for **fabrication workshops, sheet metal applications, and home workshops**. Combining **TIG DC and ARC (MMA) welding** in one compact, portable unit, it delivers precision, reliability, and efficiency.

Equipped with **high frequency (HF) start-up**, this welder allows easy arc striking without electrode contact, resulting in **cleaner welds, improved quality, and reduced risk of tungsten contamination**. This makes it especially suitable for **thinner materials** where precise control is required. A built-in **post gas function** ensures weld integrity by protecting the molten weld pool and tungsten electrode from oxidation after the arc is extinguished.

The **intuitive LED control panel** with infinitely variable dials enables smooth stepless output adjustments, ensuring accurate settings and consistent weld quality. Powered by a **4th generation inverter with over 80% energy efficiency**, the PRO 120A reduces power consumption while delivering strong performance from a standard **230v/13A supply**.

Built with a **robust metal casing and heavy-duty carry handle**, it is compact, lightweight, and durable enough for workshop environments.

**What’s Included:**

- SIP WELDMATE® PRO 120A DC TIG/ARC Inverter Welder (230v/13A)
- 3m TIG torch with consumables (2x tungsten electrodes, collets, collet bodies, ceramic nozzles, back caps)
- 3m electrode lead
- 3m earth lead
- Welding hammer/brush

**Key Features:**

- Dual process DC TIG and ARC (MMA) inverter welder
- Duty cycle @ 20°C: 120A @ 30% (TIG DC) / 100A @ 30% (MMA)
- High frequency start-up for cleaner, higher-quality welds
- Post gas function prevents oxidation and improves weld integrity
- Infinitely variable output control with LED display
- Compact, lightweight, and portable with robust metal casing
- Energy-efficient 4th generation inverter (>80%)
