The Copper Braided Flexible Cable 4010 is a high-current flexible conductor used in resistance welding equipment, welding transformers, robotic welding arms, and movable power connection positions. It is made from T2 copper and formed into a braided structure, allowing the cable to carry welding current while absorbing movement, vibration, and repeated bending during machine operation.
With a 200 mm² cross section and 500 mm length, this copper braided cable is suitable for welding systems that require a soft conductive connection between fixed and moving components. It helps reduce mechanical stress on terminals, improves current transfer stability, and supports reliable operation in compact or frequently moving welding equipment.

Product Features
High-Conductivity Copper
T2 copper provides good electrical conductivity for welding current transfer. In resistance welding systems, the current path must remain stable even when the welding arm moves, clamps, or resets repeatedly.
This copper braided cable helps reduce unnecessary resistance at the connection section and supports smoother power transmission between welding equipment components.
Flexible Braided Structure
The braided conductor is designed to bend more easily than a rigid copper bar. It can absorb movement from welding guns, transformers, movable arms, and clamping mechanisms without placing excessive stress on the terminal connection.
This flexibility is useful in equipment where the conductive part needs to move frequently but still maintain dependable electrical performance.
Stable Machining Accuracy
The cable ends and connection areas can be processed according to drawing requirements. Accurate hole position, end width, terminal shape, and overall length help the cable install correctly onto welding machines or current output terminals.
Good dimensional control reduces installation adjustment and improves compatibility with equipment that has fixed mounting points.
Heat and Load Resistance
During welding operation, the cable may experience current fluctuation, mechanical movement, and temperature rise. The braided copper structure distributes the conductor path across many copper strands, helping the cable maintain flexibility while carrying high current.
Correct cable selection, proper terminal tightening, and suitable cooling conditions can help reduce overheating and extend service life.
Customizable Design
The cable can be customized for different machine layouts, current levels, bending directions, and installation spaces. Options include different cross sections, braid widths, lengths, terminal styles, insulation sleeves, tin-plated surfaces, and reinforced end structures.
This makes the product suitable for new welding equipment manufacturing as well as replacement of worn copper flexible connectors.
Applications
The Copper Braided Flexible Cable #4010 is used as a movable current-carrying connector in welding and industrial power systems. Typical applications include:
Resistance welding machines
Spot welding guns and welding arms
Robotic welding equipment
Welding transformer secondary connections
Battery tab welding equipment
Automotive welding production lines
Appliance and sheet metal welding stations
High-current flexible grounding connections
Equipment requiring a soft copper conductor instead of a rigid copper busbar
This product is especially suitable for positions where current needs to pass through a moving or vibrating connection point.
Resistance Welding Connection Process
In a resistance welding system, the copper braided flexible cable is usually installed between the transformer output, welding arm, electrode holder, or movable conductive component. Its role is to transfer current while allowing the connected parts to move during the welding cycle.
Before installation, the terminal contact surfaces should be cleaned to reduce contact resistance. The cable should be installed without excessive twisting, sharp folding, or over-stretching. After fastening, the connection bolts should be tightened evenly so that the copper terminal face contacts the equipment surface firmly.
During operation, the braided section moves with the welding mechanism and helps absorb repeated bending. This prevents rigid stress from being transferred directly to the terminals, reducing the risk of loosening, cracking, or abnormal heating.
Process Advantages
Provides flexible current transfer for moving welding equipment
Reduces mechanical stress at conductive connection points
Helps prevent cable breakage caused by repeated bending
Suitable for compact machine layouts where rigid copper bars are difficult to install
Supports stable secondary current transmission in welding systems
Can be customized to match equipment current level and mounting space
Helps simplify replacement and maintenance of conductive connections
Compared with a rigid copper busbar, the braided cable offers better movement adaptability in dynamic welding equipment.
Connector Requirements
A flexible welding conductor should provide enough copper cross-sectional area for the required current, while also having sufficient bending flexibility for the machine movement range. The terminal connection must be firm, clean, and properly aligned to avoid local overheating.
For long-term operation, the cable should not be installed under tension. The bending radius should be suitable for the braid structure, and the cable should be protected from sharp edges, excessive torsion, oil contamination, and mechanical impact.
If the connection position operates at high current or high frequency, regular inspection of terminal temperature, bolt tightness, braid wear, and surface oxidation is recommended.
Customization Services
EAA provides custom copper braided flexible cables for welding machines, robotic welding equipment, high-current connectors, and industrial conductive assemblies. Customers can provide drawings, samples, installation dimensions, or equipment photos for customization.
Custom production is available for replacement cables, new machine development, non-standard welding equipment, and special conductive connection layouts.
Dimension Customization
Length, cross section, braid width, thickness, terminal size, hole diameter, and hole spacing can be manufactured according to customer requirements.
For movable equipment, the final cable length should consider the full movement stroke of the welding arm or fixture. A suitable length helps avoid pulling stress while keeping the installation neat.
Structure Options
The cable can be produced with different braid densities, copper strand sizes, conductor layers, end pressing methods, and terminal structures. Depending on installation needs, the ends can be drilled, pressed, welded, crimped, or shaped into specific connection forms.
Multiple-layer braided structures can be selected when higher flexibility or larger current capacity is required.
Surface Treatment
Available surface options include bare copper, tin-plated copper, anti-oxidation treatment, and insulation sleeve protection. Tin plating can help improve oxidation resistance, while insulation sleeves can protect the cable from external contact, abrasion, or accidental short-circuit risks.
The suitable surface option should be selected according to working environment, installation exposure, and maintenance requirements.
Technical Support
EAA can help review cable cross section, length, terminal design, bending direction, installation clearance, and surface treatment according to the welding equipment structure.
To improve selection accuracy, customers are encouraged to provide rated welding current, duty cycle, connection distance, movement range, installation photos, and terminal mounting dimensions.
Fast Delivery
For standard copper braided cable structures, sample production and batch supply can be arranged efficiently after drawings or samples are confirmed. For customized cables, delivery time depends on copper specification, braid structure, terminal processing, surface treatment, and order quantity.
EAA supports small-batch orders, replacement part production, and long-term supply for welding equipment manufacturers and industrial users.
