Merkle · MMA welding machines

The new Merkle LiteARC series is based on the latest innovative inverter technology, providing the best conditions for excellent welding performance.
Whether welding at a customer's premises, on site or in the workshop, the LiteARC/MobiARC series delivers ample power from a 230 V mains supply. Features such as the robust metal/plastic housing, digital display (LiteARC 180), large 50 mm2 professional connectors and TIG (WIG) function provide professional equipment in a compact package!
LiteARC 160: Weighing just five kilograms, this welding inverter offers everything needed for fast, mobile welding. Hotstart, Arcforce and Antistick functions are fitted as standard with fixed settings. TIG (WIG) welding with LiftTIG ignition is also integrated.
LiteARC 180: Compared with the LiteARC 160, this modern inverter delivers a higher output of up to 180 A. It also offers precise adjustment via a rotary encoder and digital display, manual adjustment of Hotstart and Arcforce, and a five-metre mains cable.
The LiteARC 180 has three operating modes that control the machine's maximum output and duty cycle. Depending on the mains connection, the machine's output can be limited to prevent the fuse from tripping.
The MobiARC 164 mobil keeps everything organised. Its upward-opening door provides easy access to the spacious storage compartment. Stick electrodes are readily accessible in a separate tray. Earth cables, electrode holders, gloves, a wire brush, a chipping hammer and a handheld welding shield can all be stored compactly here.

Stepless welding current adjustment up to 170 A (electrode) or 180 A (TIG), with digital display.

TIG/(WIG) welding up to 180 A with LiftTIG ignition.

The new metal/plastic housing.

Maximum mobility with an adjustable carrying and shoulder strap. Small, lightweight, easy to handle and portable, weighing just 5.0 kg.

Large professional connectors for use with standard Merkle accessories.

Extra-long connection cable: 5 m long.

Hotstart (higher electrode starting current), switchable: A higher starting current is briefly applied for reliable arc ignition.
Arcforce (dynamic current adjustment), switchable: If the electrode is pushed into the weld pool, the current increases to prevent sticking.
Antistick: If the electrode sticks, the current is switched off immediately. Welding can be restarted after a short delay once the electrode has been detached.
