Self-Shielding E71T-GS Wire: Advanced flux core design provides a stable arc and high feedability, eliminating the need for external shielding gas for ultimate portability.
Superior Weld Quality: Experience minimal spatter, excellent slag coverage, and porosity-free deposits, ensuring a clean and professional-looking bead appearance.
Versatile All-Position Use: Ideal for welding in all positions (flat, vertical, overhead), making it perfect for field repairs, home projects, and outdoor windy conditions.
Welds Through Light Scale: Powerful deoxidizing agents in the core deliver clean, reliable welds even when working on slightly rusty or mill-scale-covered carbon steel.
Durable ABS Spool: Supplied on a robust, anti-fragile ABS plastic spool that ensures smooth, consistent wire feeding and superior durability during transit and operation.
Q: My welder says it can use .030 or .035. Which should I choose?
Q: My welder says it can use .030 or .035. Which should I choose?
A: If you are welding mostly thin sheet metal (exhaust, auto panels), go with .030. If you are welding 1/8" or thicker (trailers, brackets, frames), the .035 is superior because it carries more heat into the metal.
Q: Do I need a different "Contact Tip" for this wire?
Q: Do I need a different "Contact Tip" for this wire?
A: Yes. You must use a .035 (0.9mm) contact tip. If you try to run this through a .030 tip, it will jam immediately. If you run it through a .045 tip, the arc will be unstable.
Q: Can I run .035 flux core on a standard 15-amp 120V household outlet?
Q: Can I run .035 flux core on a standard 15-amp 120V household outlet?
A: It is difficult. .035 wire requires more power to melt. You will likely trip a 15A breaker very quickly. For .035 wire, a 20A dedicated circuit or a 240V outlet is highly recommended for the best performance.
Q: Is the "E71T-GS" rating okay for building a trailer?
Q: Is the "E71T-GS" rating okay for building a trailer?
A: E71T-GS is a "General Service" wire intended for single-pass welds. For a standard utility trailer, it is widely used. However, for heavy-duty structural frames or multi-pass industrial work, some professionals prefer "E71T-11."
Q: Which polarity should I use?
Q: Which polarity should I use?
A: You MUST use DCEN (Electrode Negative / Straight Polarity). Connect your ground clamp to the Positive (+) terminal and your torch to the Negative (-) terminal. If your spatter is excessive and the weld looks like a "mountain," check your polarity first.
Q: How do I stop the wire from "bird-nesting" inside my machine?
Q: How do I stop the wire from "bird-nesting" inside my machine?
A: Since .035 is stiff, ensure your drive roll tension is not too tight (which flattens the wire) and that you are using a "knurled" drive roll specifically designed for flux core. Also, try to keep your welding lead as straight as possible while working.
