Saw Welding Machine
Digital Inverter Tri-wire Tri-arc SAW Welding Machine
Our Tri-wire tri-arc SAW machine is developed based on the all-digital submerged arc welding machine.
One system include one MZ7-1600 DC submerged-arc power source and two sets of MZE-1250 AC/DC square-wave submerged-arc power sources,and one three-wire welding tractor as well as one control panel.
Inverter Single-arc Double-wire SAW Welding Machine (big wire)
Features:
▉ The SAW welding machine adopts IGBT module full-bridge soft switching inverter technology, high efficiency, energy saving
▉ Automatic protection from phase loss, over-current, overheating, over-voltage and under-voltage
▉ Precise preset welding current, voltage and march speed
▉ Wide voltage adoption, with a voltage fluctuation of ±20%; 100% duty cycle
▉ Wire feeding auto detecting, when it is in good contact with the workpiece, wire feeding will stop aromatically, press and hold to automatically accelerate the feeding and unwinding, and automatically unwind the wire after SAW welding.
▉ Can realize efficient welding of thick plates instead of tandem wire tandem-arc SAW welding machine
▉ Two kinds of heads:: A (diameter of forward wire is 3.2mm, and that of backward wire is 4mm or 5mm)
B: (the diameter of two wires is the same)
▉ Double wires do not affect each other, do not interfere with each other, and have strong arc penetration
▉ It can realize high-effective welding to thick plate instead of double-wire double-arc welding and high-efficiency
surfacing in double-wire parallel welding
▉ It is the first choice welding power source for gantry welding, welding manipulators and other special
MZ7-1250 Inverter Hot-wire SAW Welding Machine
The MZ7-1250 hot-wire SAW welding machine is developed based on the the original submerged-arc welding machine. As its wire is preheated before welding, its molten depth will be deeper, and welding performance is higher and better.
MZE-1250 AC/DC Square-wave SAW Welding Machine
Our all-digital AC/DC square-wave SAW machine is developed on the DC SAW machine adopting the inverter technology twice, with wonderful welding result. The details is: the 3-phase 380V/50Hz power will change into HF AC after the filtration of the power frequency rectifier and role of inverter. And over high-frequency transformation and rectification, feedback control of output signal, the smooth and continuously adjustable DC will be got. After the second inversion, the DC will be changed into low-frequency AC for automatic welding of work pieces.
