The Arc 140i from Weldability is a small, portable 140 amp MMA welding power source that can be used on either a 115v or 230v supply. Housed in a rugged protective casing with recessed controls, the possibility of damage is minimized making it ideal for use in the workshop or for on-site applications.a
Using ‘Auto Sensing’ technology, there is no need to make any adjustment to the machine to suit the mains supply. The Arc 140i monitors the voltage of the supply it is connected to and adapts accordingly.
The Arc 140i weighs only 4kg, but despite its small size and low weight it still produces a staggering 120A output at 100% duty cycle. The machine is capable of producing a maximum of 150A at a 60% duty cycle allowing it to run electrodes up to 3.2mm dia.
Output current is infinitely variable between 30-140 amps via a single turn potentiometer, the machine is fan cooled and includes a thermostatic protection to eliminate the possibility of damage to the machine when used in environments of high ambient temperature.
An optional TIG torch kit is available which allows the Arc 140i to be used for scratch start TIG welding applications.
The Arc 140i is supplied in a tough, plastic carry case with a starter kit which includes a handshield, welding and ground cable & combined wire brush/chipping hammer.
