- Page 2 1. INTRODUCTION This manual contains information that will allow to take full advantage of ENEL150AC welding machine operation values and enable its safe use. All users are encouraged to read the user manual. 2. APPLICATION ENEL150AC welding machine is a modern direct and alternating current source designed mainly for TIG welding and with coated electrodes (MMA) of all types (ER-, EA-, EB-, ES-, ...) with diameters from ∅1.6 to ∅3.2.
- Page 3 Figure1 The welder is equipped with a digital display (1), indicating the values of set parameters, a knob to adjust parameter values(2), operating mode switch (5), parameters switch (3), ignition mode switch (4), selector of direct current or alternating current polarity ( 6), and indicators. There are four operation modes available to select with the button (5) (Fig.
- Page 4 There are possible two operation modes: a) with an automatic open circuit voltage reduction to the safe value of approx. 12V. This mode is automatically set when the power is turned on and after changing from another mode to MMA mode - it is signalled by continuous illumination of the LED indicating welding current Is.
