ADVANTAGES OF THE AC INDUSTRIAL INVERTER POWER SUPPLYADVANTAGES OF THE AC INVERTER POWER SUPPLY

The AC inverter has greater heat efficiencythan single-phase Ac welders so better quality welds with less splash are achieved. The AC inverter reduces electrode wear

Picture 1 shows a conventional single phase AC output. Current level drops to zero at every half cycle. Also, there is cool time, (t2 and t4) for phase control. The MIB-200A AC inverter has no

cool time for phase control or zero level, so weld current is supplied continuously. Picture 2 shows the intermittent temperature output of a conventional AC welder. The conventional AC weld has a higher peak current which causes weld splash. The AC inverter increases temperature linearly and supplies stable welding heat without creating peaks. For this reason, better heat efficiency, less splash and greater weld quality are possible.

Picture 3 shows an application of a battery tab weld. Using a DC inverter, current flows in only one direction as shown in picture 3-1. Due to the directional current flow, heat distribution to the electrodes is uneven. One electrode wears faster than the other. Using the AC inverter, weld current flows through both electrodes alternately as shown in picture 3-2, thus heat is generated equally. Using the MIB- 200A, asymmetrical electrode wear can be avoided and greater weld quality can be obtained even in series welds.

The MIB-200A, AC inverter reduces insulation burning in fusing aplications The MIB-200A, AC Inverter wave form, picture 2, allows the user to precisely control the heat into the fusing material. This improved process control can lead to a reduction in the total amount of heat required to fuse, reducing or eliminating discoloration of the commutator and excessive burning of the insulation typically associated with too much heat.
