Forney Industries 42302 Flux Core Mig Wire 0.035 in 2 Lb

Product Description

The Forney Industries 42302 is a flux core MIG welding wire designed for gasless, self-shielded welding applications. Classified E71T-GS, this 0.035-inch diameter wire runs on straight polarity (DCEN) and produces a smooth arc suited for single-pass welds on mild steel. The spool weighs 2 pounds, making it a practical choice for field repairs, maintenance welding, and light fabrication where portability matters. Licensed welders and experienced metal fabricators use this wire for outdoor work where wind would otherwise disrupt gas-shielded processes.

This wire is used in single-pass MIG welding on mild and galvanized steel in residential, agricultural, and light commercial settings. It performs well on thin to medium gauge material and does not require an external shielding gas cylinder, which simplifies setup in remote or outdoor environments. Typical applications include structural tack welds, equipment repair, and general fabrication work handled by welding professionals and skilled tradespeople.

Key Features

• E71T-GS classification for self-shielded, gasless flux core welding
• 0.035-inch wire diameter suited for thin to medium gauge mild steel
• 2 lb spool size supports portability and field use
• No external shielding gas required, reducing equipment setup time
• Single-pass weld design for repair and maintenance applications

Compatibility

Designed as an OEM-style replacement spool for standard flux core MIG welders accepting 0.035-inch wire on a 2-pound spool arbor.

Installation Notes

Loading should be performed by a qualified welder familiar with their equipment. Before changing wire, disconnect the welder from power and release tension on the drive roll. Verify the drive roll groove size matches the 0.035-inch wire diameter and set polarity to DCEN as required for flux core wire. Follow the equipment manufacturer's guidelines and applicable AWS safety standards when operating welding equipment.
