Alcotec ER4043 Wire, 3/64″, 50 lb Mini-Drum | 404350047

Alloy 4043 is one of the oldest and most widely used welding and brazing alloys. AlMigweld 4043 can be classed as a general purpose type filler alloy. The silicon additions result in improved fluidity (wetting action) to make the alloy a preferred choice by welders. The alloy is less sensitive to weld cracking and produces brighter, almost smut free welds.

Efficient Wire Feeding

With AlcoTec Almigweld 4043, smooth wire feeding now means less tangling. Our proprietary surface quality improvements mean better feeding resulting in less customer down time, which is highly important to automated setups such as factory assembly line application. An improved surface treatment on the wire enables the wire layers to travel more easily over each other during wire feeding, resulting in less scrap and rework.

QualityImprovements

Industry-leading surface quality makes AlcoTec Almigweld 4043 the optimal filler metal for aluminum welding applications requiring this alloy. This alloy has been fine-tuned with optimized chemistry to improve weld quality and appearance. Plus, welders get even better feeding, less wire resistance, and premium wire delivery with AlcoTec accessories, as well as easy usage with ESAB’s new push/pull torches.

Consistent Performance

AlcoTec Almigweld 4043 provides consistent, repeatable quality welds, which is ideal in automated & robotic welding applications. With this newly improved wire product, you get fewer welding problems and more consistent results with less production risk and greatly improved performance thanks to the latest surface treatment technology.
