AK-E71T-1C Flux-Cored Wire for All-Position Welding of Carbon and High-Strength Steels.
A CO2-shielded flux-cored wire designed for stable arc, low spatter, and easy slag removal in all positions, including vertical down welding.
Product Overview
AK-E71T-1C is a flux-cored wire for gas shielded arc welding, used with CO2 shielding gas for all-position welding, including vertical down welding. It is formulated for carbon steels and 500 MPa grade high-strength steels.
The wire delivers stable arc performance, reduced spatter, and minimal smoke during welding. Slag removal is straightforward, which supports efficient multi-pass welding and reduces inter-run cleaning time.
Application: Used to weld Carbon steels and 500MPa grade high strength steels.
Key Benefits
Stable Arc and Low Spatter.
The flux-cored formulation ensures a stable arc across the recommended current range, minimizing spatter and improving weld consistency on carbon and high-strength steels.
Easy Slag Removal
The slag produced is easy to remove after each pass, reducing the need for extensive chipping or grinding between runs.
All-Position Capability Including Vertical Down.
AK-E71T-1C is suitable for flat, horizontal, vertical, overhead, and vertical down welding, allowing one wire to cover multiple joint orientations.
Low Smoke Emissions
The wire generates less smoke during welding, improving visibility and working conditions in confined or poorly ventilated areas.
Where It Is Used
- Welding of carbon steels in structural and fabrication applications.
- Joining 500 MPa grade high-strength steels in pressure vessels, bridges, and heavy equipment.
- All-position welding in field and shop environments.
- Vertical down welding in pipeline and structural steelwork.
Who It Is For
- Welding consumable distributors supplying flux-cored wires for structural and industrial projects.
- Fabricators working with carbon and high-strength steels requiring consistent weld quality.
- Contractors performing field welding in multiple positions, including vertical down.
Problems It Solves
- Inconsistent weld quality and excessive spatter when using flux-cored wires with poor arc stability.
- Difficult slag removal that increases cleaning time and risks incomplete slag removal.
- Limited positional flexibility requiring multiple wire types for different joint orientations.

Use Guide
- Select wire diameter based on joint thickness and welding position: 1.0 mm for thin sections, 1.2 mm for medium, 1.6 mm for thicker materials.
- Set voltage and current within the recommended ranges: 1.0 mm – 15–20 V / 80–150 A; 1.2 mm – 20–32 V / 140–300 A; 1.6 mm – 20–38 V / 180–400 A.
- Ensure proper CO2 shielding gas flow and clean joint surfaces before welding to avoid porosity and contamination.
- Inspect and remove slag completely between passes to prevent inclusions and ensure sound welds.
How It Compares
AK-E71T-1C and E71T-1 both belong to the same AWS A5.20 classification and are used for CO2-shielded welding of carbon steels. AK-E71T-1C is specifically designed for all-position welding with improved slag removal and lower spatter. It differs from E71T-1 in its flux formulation, which enhances arc stability and reduces smoke. For applications requiring higher strength or specific toughness, other flux-cored wires with different classifications may be required.
