Features:

• IGBT module full-bridge soft switching inverter technology, high efficiency, energy saving Automatic protection from phase lack, overcurrent, overheating, overvoltage and undervoltage Precise presetting of 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 automaticaly, press and hold to automatically accelerate the feeding and unwinding, and automatically unwind the wire after welding.
• Can realize efficient welding of thick plates instead of tandem wire tandem-arc SAW 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 machines.

Technical Features:

1.  Thick wire ahead thin-wire-following big penetration welding.

• The front wire starts arc while touching the workpiece and the rear wire doesn't need to touch workpiecs for arc starting.
• Diameter of front wire is 3.2mm, the diameter of rear wire is 4mm, and the welding currents will be matched automatcially according to the proportation of 3:1.
• The distance between two wires is 3-6mm, the front wire can increase the molten depth, and the rear can increase the molten width.
• There is no need to bevel and leave a gap when welding on both sides of the T type weld with a plate thickness of 30mm.

• The front wire starts arc while touching the workpiece and the rear wire doesn't need to touch workpiecs for arc starting.
• The welding current of front and rear wires is automatically matched by 1:1.
• The distance between the front and rear wires is 3-6mm, the front wire increases the penetration depth, and the rear wire increases the molten width.
• It can replace double wire double arc submerged arc welding.

• Two welding wires of the same thickness are welded in parallel.
• The left and right wire welding current is automatically matched according to 1:1.
• The width of one-time welding weld can reach more than 40mm.
