CAT DZ141 140A TIG LIFT / MMA Carry Case Professional Digital Inverter Welder

• CAT MMA/Arc Digital Welder melts welding electrodes in the 1.6 mm–3.25 mm range with high frequency and efficient operation for professional work, enabling effective welding on metal surfaces, steel, stainless steel, cast iron and cellulose electrodes. • The CAT TIG LIFT/MMA Digital Inverter Welder provides two operating modes — MMA/Arc welding and TIG LIFT/Argon welding — for wider application options. • Enables smooth welding of carbon steel, alloy steels and various iron and steel metals. • The CAT Digital Welder supports the use of cellulose electrodes and is suitable for shipbuilding, storage tanks, boiler manufacturing, pipeline welding, cast steels, galvanized sheets, heavy machinery parts, and assembly and repair of non-alloy steels. • With CAT MCU inverter technology, Rutil, Basic, Cellulosic, Chrome and Cast Iron electrodes can all be used, allowing high-performance welding on all metal and iron materials. • TIG LIFT (Argon) welding technology allows clean and smooth welding on stainless steel and aluminum alloy precision metal surfaces. • TIG welding can be performed using externally purchased TIG torches and Argon gas. • Digital display with LED lighting allows precise adjustment up to 140 A for quality welding. • HOT START technology provides automatic hot start to facilitate striking the arc and prevents electrode sticking. • HOT START also delivers a higher starting current even when operating at low current settings, facilitating easy electrode ignition. • ANTI STICKING technology provides adaptive constant current to minimize spatter and electrode sticking. • ARC-FORCE technology prevents current collapse, maintaining a continuous stable current during welding.
