The MicroArc140 as the name suggests is an extremely neat and compact welding inverter. Weighing in at a slight 3kg in the hand and sized at only 100mm wide and 185mm High on your bench, this little gem is conveniently thrown over the shoulder and taken wherever you need to go. With adjustable welding current from 10 to 140 amps, and adjustable Hot Start and Arc Force, you have the flexibility to run standard general-purpose 2.5mm electrodes for light gauge work (less than 3.0mm plate) and 3.2mm electrodes for heavier metals.
Input Supply – 10A , 240 V, making this unit easy to plug and play from any power point around your workshop
Current Range – 10A – 140A
STICK (MMAW) – 140A @ 15% , using 2.5mm and 3.2mm Electrodes
DC Lift TIG – 140A @ 20%, when used with a suitable TIG torch and argon shielding gas.
Small Size & Portability – A micro 3Kg inverter in a compact (W)100 x (H)185 x (D)252mm case with carry strap.
Anti-Stick – Helps to prevent the stick electrode from sticking to the workpiece.
Adjustable Hot Start – Improves the arc start characteristics of stick electrodes
Adjustable Arc Force – Assists when stick welding in a tight corner or joint fit-up.
Over Temperature Protection - Cut out protection has been fitted to the power source
Twistlock Electrode Holder – Allows quick electrode changeovers and locks rods securely in place for welding.
Electrode Holder & Lead – 3m Long
Digital Blue LED Amp Meter - Bright Blue LED’s allow for accurate setting and improved visibility of the welding amperage even outdoors & in bright light conditions.
