This welder is equipped with features that make it much easier arc ignition and hold:
hot start - for easier ignition of electric arc;
arc force - afterburner arc - to stabilize the arc and improve the quality of welding (arc holds a
slight change in the distance between the electrode and the workpiece);
anti stick - protection against welding electrodes during welding.
SAFETY FEATURES
Protection from abnormal conditions: Under the load bearing elements heat up considerably.
Therefore, in the device power circuits are protected by means of thermal fuse. In the event of an
overload or insufficient cooling unit indicator light availability errors on the front panel, wherein the
welding current is forcibly reduced to the minimum in order to avoid failure of the apparatus. The
welding can be continued after the machine has cooled down, and the light will turn off the security
indicator.
Soft-start function: This function is implemented for smooth charging of the electrolytic capacitor
input filter to prevent premature failure of the power switch and the input circuit elements when the
device is switched.
Attention! It is strictly forbidden to connect the unit to AC 380V in order to avoid damage to
the input circuits of the machine.
