Common Questions

How do I choose the right electrode for my job?

Start with your welding process (Stick, MIG, or TIG) and base material (mild steel, stainless, or aluminum). For general structural stick welding on clean steel, run 7018. For dirty or rusty steel or outdoor work, 6011 handles it. For MIG welding mild steel, ER70S-6 is the standard. For TIG, we carry ER70S-6 (mild steel), ER308L and ER316L (stainless), and ER4043 (aluminum). Not sure? Browse The Weld Room for process-specific guides, or use the Shop All page to filter by product type.

Do you offer wholesale or bulk pricing?

Yes. Copper Bridge offers tiered pricing for higher volume orders — from pallet quantities (2,000 lb) up to truckloads (44,000 lb). Visit our Wholesale page to request a quote. Quotes usually come back within 1 business day.

Where do you ship from, and how fast will I get my order?

All orders ship from our warehouse in Riverside, CA. Most orders leave within 1–2 business days. We ship to the contiguous US only. Orders over 00 ship free.

Are your products AWS classified?

Yes. All Copper Bridge consumables are labeled to their applicable AWS classifications — including ER70S-6, E7018, E71T-GS, and E308L-16. Manufactured by Jinlong Welding Electrode Co. with over 20 years of production experience. SDS and TDS on file for every product. COA/COC available on request.

What is the difference between 6011 and 7018 electrodes?

6011 is an AC/DC all-position rod that runs well on dirty, rusty, or coated steel — ideal for field repairs and outdoor work. 7018 is a low-hydrogen rod that produces cleaner, stronger welds on prepared steel — ideal for structural work and code-compliant joints.

Do you carry TIG welding rods?

Yes. We stock TIG rods in ER70S-6 (mild steel), ER308L and ER316L (stainless), and ER4043 (aluminum). Available in 1/16", 3/32", and 1/8" diameters. Browse TIG on the Shop All page.

Popcorn weld? Don’t touch the machine yet. Check this first: Polarity wrong leads = spatter + porosity Arc length long arc = too hot + messy bead Rod match: 6011 = dirty steel / wind / repairs 7018 = clean steel / smoother welds (keep it dry)

Gasless flux core gets a bad rep because most people run it wrong. If your weld looks like popcorn (spatter), swiss cheese (porosity), or you’re fighting stubbing/hissing… do these 3 checks: Polarity (most gasless = DCEN) Drag angle (10–15°) Stickout (aim ~3/4", don’t let it creep long)
