Short description

The STICKY 251 DCL Professional MMA / Lift TIG inverter welder is a high-performance inverter welder designed for industrial use, which uses the latest IGBT inverter technology. Its compact size, low weight and excellent efficiency make it an ideal choice for workshops, assembly halls and field work.

Stable arc, excellent seam quality

Thanks to advanced digital PWM control, the machine provides an extremely stable and concentrated arc. Automatic Hot Start and Arc Force functions make arc ignition easier, reduce sticking and produce a smooth, aesthetic weld seam.

MMA and Lift TIG mode

STICKY 251 DCL is suitable for:

For MMA (stick electrode) welding
Lift for TIG welding

Its wide current range (20–250 A) allows the use of different electrodes, whether rutile, basic or cellulose electrodes.

Pulse function – more control

Pulse mode provides finer control during welding. Adjustable pulse frequency, duty cycle and base current help you work precisely, especially with thinner materials.
