FAQ
Which Rod Size Should I Choose?
Pick the rod diameter to match the metal thickness and the joint you’re welding. Use smaller diameters like .045″ or 1/16″ for thin sheet and out-of-position work, move to 3/32″ for medium‑thickness pieces, and choose 1/8″ for heavier sections where you need more filler.
If you’re unsure, test on scrap with the amperage you plan to run to confirm puddle control and fusion.
How Clean Do The Rods Need To Be?
You should keep the rods and the base metal as clean as practical because contamination causes porosity and poor fusion; wipe oily surfaces with acetone and wire‑brush heavy rust. ER70S-2 contains multiple deoxidizers that help when you can’t get everything perfectly clean, but that’s not a substitute for proper prep.
If rods arrive loosely wrapped instead of in a tube, inspect and clean them before use and store them in a dry, sealed container to avoid moisture and dust.
Can I Use ER70S-2 For Both TIG And MIG?
Yes, ER70S-2 chemistry is used for both TIG and MIG applications, but treat them differently: TIG uses argon shielding and fingertip control of the rod, while MIG setups require appropriate transfer modes and gas mixes such as CO2 or argon‑CO2 blends. Match your machine settings, filler diameter, and technique to the process, and always try a short trial weld on scrap to dial in parameters before working on the actual part.
What Welders Prefer
You’ll usually prioritize diameter and handling, packaging and pack size, and whether the rod has a coating for smoother feeding — PGN’s copper coating helps with longer runs while Hy-weld gives you different weight options to suit shop restocking. Most pick the 1/16\ choices for controlled, consistent puddles and the .045\ when thinner filler is needed, and everyone pays close attention to whether rods arrive sealed or loose because cleanliness affects porosity and prep time.
Wrapping Up
Picking the right ER70S-2 TIG filler rod affects weld strength, appearance, and how much cleanup you do. You’ll benefit from picking a rod that matches your typical projects: reach for small sealed packs for precision work, buy mid-size packs for regular shop use, and choose 10 lb containers if you need continuous supply.
Pay attention to packaging and deoxidizer chemistry when you work on rusty or mill-scaled steel, and keep a high-rated brand on hand for the jobs where consistency matters most.
