501D wire feeding tube

The 501D wire feeding tube is a core accessory that is compatible with the MB 501D series gas shielded welding gun (especially water-cooled MIG welding gun). It is mainly used to transport welding wire carefully and smoothly during the welding process, and is a key component for protecting welding stability and weld quality. Its detailed characteristics are as follows:

Material and Structure

Core guide wire layer: The mainstream materials used are graphite or PTFE. The graphite layer has a relatively low friction coefficient and is suitable for materials such as aluminum welding wire that are prone to adhesion, resulting in low wire feeding resistance; Teflon material is resistant to high temperatures (based on actual reports) and corrosion, suitable for various types of welding wires, and has a relatively long service life.

Outer protection: Some models are wrapped in nylon or spring steel to enhance the bending resistance and performance of the hose, avoiding damage to the pipe body caused by dragging and bending during welding, and adapting to complex working environments.

Interface design: European standard interfaces are used at both ends, with some parts equipped with sealing gaskets, which are tightly connected to the wire feeding mechanism and conductive nozzle of the 501D welding gun. It is confirmed that there is no offset or jamming during the wire feeding process, and the sealing is improved to reduce the entry of impurities.

performance advantage

Strong wire feeding smoothness: The graphite/PTFE inner layer material has a low friction coefficient, which can effectively prevent the welding wire from sticking to the pipe wall. It is especially suitable for aluminum welding wire, steel welding wire, and stainless steel welding wire with a diameter of 0.8-1.6mm. It ensures stable wire feeding accuracy during high-speed welding and reduces weld defects.

Suitable for high load operations: Equipped with MB 501D welding gun with a rated current specification of 500A, it supports 90% duty cycle (continuous load rate). In high-intensity scenarios such as thick plate welding and heavy-duty fabrication, the pipe body is resistant to high temperatures (based on actual reports), aging, and is not easily affected by heat deformation that affects the wire feeding effect.

Balancing flexibility and practicality: The hose has good overall flexibility, making it easy to adjust the welding gun angle during welding and reducing operational fatigue; The outer protective material is wear-resistant and drag resistant, extending its service life and reducing the frequency of accessory replacement.

Specifications and Applications

Core specifications:

Inner diameter x outer diameter: commonly 4.0 x 2.0mm, 4.7 x 2.7mm, 2.3 x 4.7mm, 2.9 x 4.7mm, etc., suitable for different diameter welding wires (mainly 0.8-1.6mm, partially supporting 0.9-2.0mm large diameter welding wires).

Length: Standard lengths of 3.5 meters, 4.5 meters, 5.5 meters, can also be customized according to demand, and some reputation offers bulk specifications of 50 meters per roll.

Adaptation interface: European quick connect interface, compatible with Binzel, TBI and other reputable 501D series welding guns, can match the wire feeding mechanism of mainstream welding machines such as Lincoln and Miller.

Application scenarios: Mainly used for gas shielded welding (MIG/MAG welding), especially suitable for welding aluminum, welding iron, welding stainless steel and other scenarios. It is widely used in industrial industries such as heavy machinery manufacturing, steel structure welding, and automotive parts processing that require high wire feeding accuracy.
