Inverter DC Manual Arc Welding Machine

Inverter DC Manual Arc Welding Machineis manufactured with advanced inverter technology. With high-power component MOSFETS and by adopting PWM technology, the inverter convert the DC voltage, which is rectified from input AC voltage, to high 100KHz frequency AC voltage; as a consequence, the voltage is transformed and rectified. Therefore, it results the much more small-sized of the main transformer and lighter in weight of the inverter welder, which rates the performance of welding by 30%. The high frequency oscillation, which enables the output of the high frequency DC, is employed in the arc-starting system. The features of this product are as following: stable output, reliable, completely portable, efficient and low noise generated while welding is performed. TIG welding is available for TIG160S/180S/200S/300S. Both MMA and TIG are welding are available for TIG180A, TIG180P, TIG200P. are models of new plastic products, the cover of which are made of anti-combustible ABS material. It possesses more advantages compared to machines of iron case, such as beautiful design, excellent insulation, and waterproof. During the performance of MMA welding, this welding machine is featured with the stability of output, and the availability of arc force modulation. In case of normal arc input voltage, the stability of welding current output is not frustrated with variation of arc length, therefore it results in stable performance of welding operation, of which the arc is of elasticity. In case of unavailable length of arc and low input voltage, welding output current increases while arc voltage decreases, as a consequence, the length of arc, which is not sufficient, will automatically compensate and the modulation of arc force is accessible. In case that the input arc voltage is too low to maintain arc, the output of this welding equipment descends steeply, which avoid the splash generated due to over current input. During the performance of TIG welding, this welding equipment is featured with the stability of output current and that the welding current output does not vary with variation of the length of arc. In case of short circuit of electrode, the voltage automatically decreases to 0V, which limits the impairment of electrode and pollution to environment. Guarantee of maintenance for main engine is one year, excluding other spare parts. During the guarantee maintenance period, all maintenance is free of charge, excluding the deliberated damage to this welding equipment. Only qualified technician are authorized to carry out the repairs task of this welding machine in case of machine fault.
