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.
OPERATION INSTRUCTION
installation placement
• Welding machine must be protected from direct sunlight, rain, moisture, corrosive and corrosive substances
and vibration. The placement of the machine, keep it clean and ensure good ventilation.
• Ambient temperature during welding: -10 ~ + 40 ° C during transport and storage: -25 ~ + 55 ° C.
• Relative humidity at 40 ° C: ≤ 50%, at 20 ° C: ≤ 90%.
