The Jasic Arc 140 is a cost effective, compact and highly portable ‘plug and go’ MMA inverter.  Extremely small in size and lightweight, the Jasic Arc 140 is a great portable tool for mobile use or as a lower cost yet quality machine.  Able to weld up to a 3.2mm rod, they are excellent for home and agricultural repairs as well as site welding.


The Jasic arc 140 produces excellent weld characteristics and benefits from easy arc starting and a stable and reliable arc.  Jasic Pro Arc inverters feature IGBT inverter technology making it possible to use them safely when powered by a generator.

This arc inverter benefits from ‘Lift TIG’ allowing the user to TIG weld with the same power source.  If you would like to make the most of this function, please add the TIG torch by using the drop down options above.  Save by buying your TIG torch with the machine at a reduced price.  Torch supplied will be WP17 type unless specified otherwise. TIG torch spares and filler rods are available online.

The Jasic Pro Arc MMA inverter is a compact and lightweight machine weighing just 4.7kg. Rubber mouldings and handle make it perfect for on site maintenance tasks.  A duty cycle of 140 Amps at 35 % allows use of up to 3.2mm stick rods.


Jasic arc welding inverters come with an excellent 5 year warranty.  The warranties are not subject to service plans and in our experience, are always dealt with quickly and fairly too.


Jasic inverters have a certified ISO 9001 quality management system and a product range that fully complies with CE, RoHS, C-TICK, CSA and CCC standard.


Package Includes
: MMA inverter power source, Cable plugs, Operating instructions, 5 year extended warranty.

Not Included:  MMA leads (Please choose from options dropdown above), Mains plug, Electrodes, TIG torch (Available on options drop down above), TIG torch spares, adaptor & consumables, Shielding gas, Filler rods, PPE (Welding helmet, gloves, etc)


NOTE:  TIG Torch will require an earth lead.  If the machine, lead set and TIG torch is purchased, the TIG torch can be used with the earth lead from the MMA lead set.  See TIG torch in related products below.

If you would like to specify the MMA lead electrode holder type, please put a note when checking out.  We are able to supply a twist type or crocodile type electrode holder (both the same price).


Supported by a 5 Year Manufacturers Warranty.

Wilkinson Star, the UK importer/distributor of Jasic machines also offer component level repair both in and out of warranty time frames. In the unlikely event of a machine going wrong in the 5 year Jasic welder warranty period, arrangements will be made, at their expense to collect and return the equipment for repair.  In our experience, this is usually completed within a week, which compared to other leading brands is very good.
