MZ7 Series of Inverter Hot-wire SAW Welding Machine

Features:

▉  IGBT module, all-bridge soft-switch inverter technology, high efficiency and power saving

▉  Automatic protection from phase lacking, over current, over-heat, over/under voltage

▉  Precise presetting of welding current, voltage and marching speed

▉  CC/CV, suitable for both thin and thick wires

▉  Support SAW, MMA, and gouging

▉  Excellent touchable arc starting and no-touching arc starting function

▉  Strong arc penetration force, different welding tractors are optional

▉  Wire feeding auto checking, while the wire connects the work-pieces well, wire-feeding stops automatically, press the wire sending/back without release, wire sending or wire feeding will be speed up automatically, wire will be drawn back automatically after welding finish

 ▉  Wide voltage adoption, ±20%

▉  Can weld mild steel and stainless steel, the first-choice power source of gantry welding and operator.

▉ In hot wire welding, the welding wire is preheated to 500-900℃ in advance before being fed into the arc area, therefore, the molten speed of unit current wire is increased, and the welding efficiency is increased accordingly

▉ In hot wire welding, under the same current conditions, the welding wire melting speed can be increased by about 15-30%; the heat input of the weld is reduced by 10-20%; the penetration depth is increased by 10-20%; the flux consumption is reduced by 10-30%
