TOKO Welding Consumables Overview

TOKO E81T1-K2C Flux-Cored Welding Wire

TOKO AWS A5.29 E81T1-K2C, flux cored welding wire is used for high-strength, low-alloy steel welding in low-temperature environments.It supports all-position welding with 100% CO2 shielding gas and DC+ polarity. The wire offers stable arc, minimal spatter, and good toughness down to -60°C, ideal for robust welds. Use 1.2mm or 1.6mm diameter, 140–320A current, and 20–32V voltage. Clean the surface and store wire in a dry place to avoid defects.
