50m Roll of 70mm² Flexible Welding/Battery Cable

Built for High-Current Power Delivery in Demanding Australian Environments

The Austech 50m Roll of 70mm² Flexible Welding/Battery Cable is a heavy-duty flexible welding and battery cable designed for installers and builders who need dependable current delivery where vibration, movement and heat are part of the job. Whether you’re wiring a starter/battery system or feeding an inverter, or running a welding power lead, this single-core cable is engineered to support stable performance and confident routing in tight bays and busy electrical enclosures.

At the core is finely stranded Class 5/6 plain copper, chosen to improve flexibility and help reduce fatigue where cables are frequently handled or exposed to ongoing vibration. That flexibility also makes terminations easier, helping you achieve cleaner bends, better cable management and a more professional finish—especially important in 4WD and touring engine bays where access is limited.

Double-Insulated Construction for Practical Protection

This cable uses a double-insulated build: an inner V90 PVC insulation layer paired with a tough UV-stabilised NBR (rubber) outer sheath. In real-world installs, that combination helps reduce the risk of premature insulation wear from abrasion, rubbing against trays or chassis edges, and exposure to sunlight in outdoor or canopy-mounted setups. It’s also designed with flame and heat-retardant properties to support safer installations in workshop, automotive and industrial environments.

Designed to Reduce Voltage Drop Where It Matters

In high-current DC systems, voltage drop can quickly become the difference between equipment that performs as expected and equipment that runs hot, underperforms or triggers low-voltage cut-outs. By selecting the correct conductor size for your run length and load, the Austech 50m Roll of 70mm² Flexible Welding/Battery Cable helps maintain efficient power transfer—supporting better output from inverters and DC-DC chargers and more consistent operation across battery interconnect and welding lead applications.

Installation Confidence for Trades and DIY Builds

Every build is different, but the priorities stay the same: electrical reliability, mechanical durability and straightforward installation. This cable is commonly used across 4WD and touring builds, caravan and marine electrical upgrades, workshop welding setups, and industrial switchboard-style applications where a flexible, robust single core is preferred. The outer sheath is easy to identify, and the cable construction supports neat routing through conduits, trays and protective sleeving.

Key Features

• Flexible Class 5/6 copper stranding for easier routing and vibration resistance
• Double insulation with V90 PVC inner layer and UV-stabilised NBR outer sheath
• Flame and heat-retardant properties for demanding electrical environments
• UV-resistant outer sheath suited to outdoor and canopy installations
• Temperature-rated design intended for higher-heat installations (refer to specs for limits)

Notes for Correct Selection

Current carrying capacity depends on installation conditions. Consider run length, ambient temperature, bundling, ventilation, duty cycle and termination quality when selecting cable size for your system. For best results, use appropriately rated lugs, crimp tools and circuit protection, and have installations completed or checked by a licensed electrician where required.
