The Jasic Pro Arc 140 inverter welder is a very compact yet powerful inverter MMA and DC lift -TIG set with dual voltage input. The inverting frequency of 33~43kHz greatly reduces the size and weight of the welder. It is extremely portable weighing in at only 4.7kg, making it ideal for both shop and site use. It pushes out 180A from 230v mains supplies and 140 Amps from 110v site supplies, so will run up to 4.0mm rods with total ease.

Equipped with IGBT Inverter technology, it is designed with the professional user in mind. As well as the IGBT Inverter technology, it has a singluar PCB for improved efficiency and maintenance. The technologically advanced inverter is extremely user-friendly and offers reliable and consistant arc performance. The Arc 140 also offers lift TIG functionality, making it an ideal choice for maintenance and light fabrication.

The duty cycles are measured at a full 40°C and it can be run from a generator source. It can also be used for Lift-Start TIG with the addition of the optional TIG Kit & Argon gas supply. It is all rounded off with a stylish, ergonomic and robust case which shows off the quality, as well as makes use of a protective rubber oil finishing to the mouldings and handle. Aside from the lightweight inverter welder itself, it can also be coupled with an additional high quality optional 3m lead set.


There is no compromise on the quality of this equipment - such is Jasic's confidence in this technology Wilkinson Star offer an unparalleled 5 year warranty - the first of its kind in the welding industry. JASIC has a certified ISO 9001 quality management system and a product range that fully complies with CE, RoHS, C-TICK, CSA and CCC standard.
