This tractor is suitable for AC or DC tandem power supply, tandem wire submerged arc welding. It can support welding of one weld, or two parallel welds, or fillet welding. It is used for welding various types of medium wire feeding heads, box beams of thick steel plates, H-beams, etc. It can such materials like carbon steel, low-alloy steel, heat-resistant steel, etc.

Main Parameters

    The G-type deep penetration pulse welding machine is a further electromagnetic compression arc welding machine based on high-speed pulse welding machine, which makes the arc density higher, the arc more concentrated, and the arc more straight to achieve greater penetration, which is conducive to welding medium thick plates. The welding speed is faster and the heat input is low. Especially when using double 1.6mm welding wire for high current welding, the matching power supply is larger. If using 1.6mm solid core welding wire, the welding current is 300A, and the matching voltage can be 27V, which is very suitable for metals with high heat input requirements.

    Gas shielded welding with flux cored wire has been promoted and widely used in industries such as shipbuilding, steel structures, bridges, automobiles, and mining machinery for many years. The gas shielded welding of flux cored wire mainly uses pure CO2 gas or 20% CO2+80% Ar as the shielding gas, and the process is very mature. However, there are still some shortcomings in the application process, mainly including: firstly, the welding wire is prone to moisture; Secondly, when welding with 1.2mm flux cored wire at currents below 160A, there are small balls  at the end of the wire, which is not conducive to controlling the arc and molten pool. Therefore, welding with currents above 160A is mostly used; Thirdly, the depth of melting is shallow, the arc is weak, and the penetration power is not strong.

     When we use deep penetration high-speed pulse or high-speed pulse welding in flux cored wire, even the current is 80A, arc spray transition can also be realized. And there are no small balls at the end of wire when arc burns. The molten pool and arc are easy to control, and the molten pool is clear; The melting depth is greater,  30% greater than that of the core wire in general DC gas shielded welding. High speed pulse arc has greater stirring force and stronger arc force. Therefore, it is easier for flux cored wire welding slag and gas to overflow during welding.

3. Can realize three-wire or four-wire welding together with DC SAW welding machine and realize quick and high efficiency welding

Technical Parameters

The G-type deep penetration pulse welding machine is a further electromagnetic compression arc welding machine based on high-speed pulse welding machine. When the arc is compressed, the arc density is higher, the arc is more concentrated, and the arc is more straight to achieve greater penetration, which is conducive to welding medium thick plates. The welding speed is faster and the heat input is low. Especially when using 1.6mm or more welding wire for high current welding, the matching power supply is larger. If using 1.6mm solid core welding wire, the welding current is 300A, and the matching voltage can be 28V, which is very useful for metals with high heat input requirements.
