Customer Questions & Answers
-
Question:
What is the composition of Blue Demon E71T-11 flux core welding wire?
Answer: The Blue Demon E71T-11 flux core welding wire is composed primarily of mild steel with a blend of various alloys that enhance its performance. This wire is specifically designed to provide excellent arc stability and a smooth finish, making it ideal for welding mild steel without the need for shielding gas. Many welders prefer this wire for its ability to handle diverse environments, including outdoor conditions, where wind might affect gas shielded welding. It is particularly effective for projects like home repairs, automotive work, and metal fabrications. -
Question:
What size of the Blue Demon E71T-11 wire is suitable for my welding machine?
Answer: The Blue Demon E71T-11 welding wire comes in a .030 inch diameter, which is compatible with most MIG welding machines designed for gasless flux core operation. This size is ideal for various applications, including light to medium steel fabrications and repairs. When selecting the wire diameter, consider the thickness of materials you are working with. For instance, .030 wire is perfect for welding thinner materials like sheet metal while providing ease of control and feeding through the machine. -
Question:
Can I use Blue Demon E71T-11 welding wire for outdoor projects?
Answer: Yes, the Blue Demon E71T-11 welding wire is specifically designed for gasless applications, making it well-suited for outdoor use. Unlike traditional MIG welding that requires shielding gas, this flux core wire generates its own shielding gas during the welding process, protecting the weld from atmospheric contaminants, especially in windy conditions. This feature makes it a go-to choice for outdoor projects such as fence construction, metal fabrications, and machinery repairs in open environments. -
Question:
How does the Blue Demon E71T-11 welding wire perform with different welding machines?
Answer: The Blue Demon E71T-11 wire exhibits excellent performance across a variety of welding machines that are equipped for flux core operation. It's compatible with both portable and industrial-grade welders, allowing users to achieve a stable arc and high-quality welds. Many users have noted its smooth feeding and arc stability, which minimize spatter and improve overall work quality. Those using voltage-adjustable welders often find it particularly effective for customizing settings based on material thickness. -
Question:
What types of materials can I weld with Blue Demon E71T-11?
Answer: You can weld a variety of materials with the Blue Demon E71T-11 welding wire, primarily focusing on mild steel and some low alloy steels. This makes it suitable for a range of applications, from automotive repairs to structural fabrication. The wire’s flux formula also allows for welding dissimilar metals, making it a versatile choice for hobbyists and professionals alike. Users often apply this wire in projects like building frames, repairing equipment, or crafting metal art. -
Question:
Is the Blue Demon E71T-11 wire suitable for beginners?
Answer: Absolutely! The Blue Demon E71T-11 is a popular choice among beginners due to its gasless operation and ease of use. It allows novices to practice without the complexities of managing a shielding gas. Users find that it produces a forgiving weld pool that facilitates learning and adjustment. Therefore, it’s excellent for practice sessions and smaller home projects, enabling newcomers to develop their skills in welding with minimal fuss. -
Question:
What is the spool size of the Blue Demon E71T-11 welding wire?
Answer: The Blue Demon E71T-11 welding wire comes in a convenient 2LB spool size. This compact spool is ideal for both occasional and frequent welding tasks, allowing users to easily change out the wire without handling bulky rolls. Many hobbyists appreciate this size for its portability, making it easier to store and transport for different projects. It’s perfect for projects where space and weight are considerations, like mobile welding jobs or DIY repairs at home. -
Question:
What is the recommended shielding technique when using Blue Demon E71T-11?
Answer: When using the Blue Demon E71T-11 gasless flux core welding wire, no additional shielding gas is necessary. The flux within the wire creates its own shielding during the welding process, which protects the weld from oxidation. As a best practice, maintain a proper travel speed and technique to ensure consistent weld quality. Many users recommend adjusting your technique according to the material thickness and position, ensuring that the flux can effectively shield the weld pool from impurities in the air. -
Question:
What are the key benefits of using gasless flux core welding wire like Blue Demon E71T-11?
Answer: Using gasless flux core welding wire like Blue Demon E71T-11 offers several advantages, including portability and ease of use. Since it doesn’t require a separate gas source, it’s an ideal option for fieldwork and outdoor projects. Additionally, the ability to weld in windy conditions without gas interference is a significant benefit. Users appreciate the minimal setup required, allowing quick transitions between projects. This type of wire is perfect for DIYers, hobbyists, and professionals needing flexibility on-site. -

BlueDemon Welding Wire Editorial Review
The Blue Demon E71T-11 x .035 x 1LB Spool Gasless Flux Core Welding Wire is a high-quality product suitable for general-purpose steel welding. Made in the USA, the wire has a long shelf life that can be extended by keeping it in the packaging or by wiping off rust with mineral spirits. The wire is ferrous and does not require gas to function. The only notable difference between this and Blue Demon E71TGS wire is that T-11 wire has a multi-pass rating and is better suited to thicker materials. The wire is not suitable for welding aluminum.
