The Clarke MMA140A provides a perfect blend of quality construction, power and control that makes it ideal for home, garage or mobile repairs. Ultra-lightweight, weighing in at less than 5kg, this welder is ideal for portable use and provides superior quality ARC welding. Because of the versatility & simplicity of MMA welding, it requires less skill to operate and is used primarily to weld iron and steels (including stainless steel) up to 5mm thick.
However, nickel and copper can also be welded using this method. This inverter welder is able to output between 20 and 140A, with an input voltage of 230V/50Hz. The process of MMA/ARC welding uses a coated consumable electrode (stick) to lay the weld; therefore an additional welding kit is not required. This model has inverter technology that has a high switching frequency, allowing the welder to be more efficient than non-inverter transformer-type welders. Designed by professionals to be easy to use whilst working, this unit comes with a large current control knob - to allow for easy usage when wearing welding gloves - plus, a digital display that shows the variable output current clearly, so you are able to see it through your mask.
Advanced functions of this welder include built-in Hot Start, which eases striking the arc; Arc Force, which gives a temporary increase of the output current if the arc turns too short, and Anti Stick, which switches off the power source if the electrode sticks to the material. To enhance operator safety the welder also incorporates a Voltage Reduction Safety Device, also known as Anti-Shock, where the output voltage is automatically reduced when the welder is not in use. This MMA140A requires a 16 Amp, 230 Volt supply. Weld return cable plus a fixed carry handle.
Electrode diameter: 1.6-3.2mm. Maximum effective input current: 25.1A. Open circuit voltage: 60V Dimensions (L x W x H): 365x130x250mm.
