About this item
- GASLESS: E71T-11 does not require a shielding gas. The flux core inside the wire acts in place of the shielding gas. This makes the wire very versatile and perfect for mobile jobs, outdoor jobs, and people who do not have access to shielding gas.
- VERSATILE: This wire can be used on carbon and galvanized steel in a variety of applications including maintenance repairs, automotive repairs, light structural work, and more!
- EASY TO USE: This wire is less sensitive to contaminants in the base metal such as rust and mill scale, allowing you to still make quality welds even in suboptimal conditions. Our wire also has low spatter and slag that is easily removable.
- USABILITY: E71T-11 runs very similarly to E71T-GS. However, E71T-11 is designed for multi-pass operations. This wire runs on DCEN (Direct Current Electrode Negative) and can be used in the flat, horizontal, vertical upwards, and overhead positions.
- COMPOSITION: Our wire contains Silicon for better fluidity of the weld pool, Manganese for improved hardness, and other deoxidizers to ensure optimal performance.

- Reviewed in Canada on September 27, 2024Verified PurchaseI've used a bunch of different brands. This has worked the best so far. You get that noticable "sizzling bacon" sound with this wire and it makes nice welds with flux core with minimal splatter.

- Reviewed in Canada on July 9, 2023Verified PurchaseExcellent product and price. I used today and worked as expected.
The only thing that I want to mention is the fact that I had to return the first order because the spool was damaged, likely due to poor packing (an envelope!). However, the replacement was unexpectedly quick.
I recommend this product.

- Reviewed in Canada on December 23, 2023Verified PurchaseSwapped this wire in when I ran out of my last spool of Lincoln wire. The old wire was tripping the breaker and spattering all over the place, this new welding wire burns in way better and hotter, made my welding project a breeze
- Reviewed in Canada on June 24, 2023Verified PurchaseEach welder/ wire combination is going to be different .Just the way it is in the welding world .I have been using this in my new HZXVOGEN multi purpose welder and it seems to work very well after getting the
voltage and current in the right place .I would defenately buy it again..

5.0 out of 5 stars Best flux core wire hands down!
Verified PurchaseI absolutely love this wire. I run it in my 125 Titanium flux core mig welder. I will never use any other brand of wire. Love the results this wire produces for me. I have fabricated many projects using this wire. The most recent being some rock sliders for my truck.

5.0 out of 5 stars Great stuff
Verified PurchaseGoing on my 6th or 7th roll if this wire, .030. Works great, it's cool that you usually get a sticker with them. Easy to use, seems like it burns a brighter color than your run of the mill Lincoln stuff or maybe whiter? Not sure. Lol
I do a lot of thin gauge welding with my job but I have also used this stuff to build thicker gauge items such as stairs and hand rails or even 1/4 plate in non structural areas.
The only thing I do have a complaint about is 鶹s packaging. EVERYTIME they ship this in a paper bag envelope and the spools get beat up. Come on 鶹, do better!
