11015B - Hobart Megafil 1100M .045 Metal Core Wire 35lb Spool E110C

Crack-Resistant Wire for Heavy-Duty Steel

When your job involves welding high-strength steel like T1 or HY-100, you need a wire that is as tough as the base metal. The Hobart Megafil 1100M is a .045-inch metal-cored wire built for the heavy hitters—cranes, earthmovers, and offshore rigs. Unlike standard wires, this filler metal delivers a massive 120,000 psi tensile strength, ensuring your welds hold up under extreme stress and heavy loads. It is designed to run smooth and fast, giving you the deposition rates of a flux-cored wire with the clean finish and efficiency of a solid wire.

One of the biggest challenges with high-strength steel is cracking, often caused by hydrogen. The Megafil 1100M solves this with a hermetically sealed, seamless design that keeps moisture out. This results in incredibly low hydrogen levels in your weld deposit, drastically reducing the risk of cracking and the need for expensive repairs later. You will notice the difference in the arc stability and the lack of spatter, which means less time grinding and more time welding. It runs best on a mix of Argon and CO2, giving you a comfortable, controllable puddle in flat and horizontal positions.

Whether you are repairing a boom on a crane or fabricating a pressure vessel, this wire gives you the confidence that your welds will pass X-ray and ultrasound testing. The 35lb spool size is perfect for shop use, providing enough material for long runs without the bulk of a drum. If you are looking for a wire that handles the toughest steels without fighting you, the Hobart Megafil 1100M is the tool for the job.
