1, increase the secondary coil cooling surface area to greatest extent.

2, to greatest extent the primary winding outside is exposed to outer surface, strengthen the heat-sinking capability of primary winding.

3, make the coil trend help Natural Heat Convection most.

Six, in secondary coil, do not have tap, be connected on the rectifier bridge.Rectifier output can and be finished the motor vehicle primed starting to motor vehicle storage battery emergent charging.

Seven, secondary coil be provided with by force, in, weak and common port ground exchanges output, export by the plate face by the aluminium sheet transition.Be used for carrying out the preliminary adjusting of institute's use welding rod thickness.

Eight, primary winding is provided with a plurality of taps, is used for realizing the classification adjusting of secondary coil output voltage, output current by plate face change over switch.

Nine, the plate face is provided with motor vehicle primed starting binding post, realizes motor vehicle primed starting and storage battery emergent charging.

Ten, the safety of storage battery when the safety of storage battery and emergent charging when guaranteeing the motor vehicle primed starting, the plate face is installed two D.C. voltmeters, is used for monitoring 12V and 24V VD.

11, the plate face is provided with the ac arc wedling machine working station indicator.

12, back plate face is provided with two wiring of input power source posts (the input power supply is that 220V is civilian).
