oxy/acetylene filler metal?

[Ken_CT]

Can anyone give me some pointers on what type of welding wire for oxy/acetylene welding of mild steel? I have some 3/32" ER70S-6 and some 1/16" RG-60, but I don't know what is best for general welding. I can't seem to find any info on gas welding rod recommendations. Thanks.

The company that refills your tanks should be able to help you with the rod you need. I usually stick weld but on occassion have used steel coat hangers when using a torch.

Learn sumpthin new everyday. Here's what AirGas has. I suspect that I've only used RG45 cuz the store I go to only has one choice. 'Course, I've used coat hangers and bailing wire too.

Edit: link didn't work right for me. Here's the path: All Categories > Welding Products > Filler Metal > Gas Welding Rod > Gas Welding Rod - Carbon Steel

I did ask at the welding supply store, but the regular counterman must have been at lunch. They had a young man on the counter who was not very knowledgeable on the subject. He knew about as much as I did. /forums/images/graemlins/frown.gif

What is the differrence between R-45 and R-60?

I use 1/8" RG45 36" long (copper coated), stuff works great for just about anything, good filler properties as well.

Sorry, As I said in the previous post I use coat hangers, flux coated brazing rod or silverbraze rod. If your going to stick weld with an arc welder I could suggest various rods. Hopefully some others will log on with their input.
Or you could check the phone book for other places that sell oxy / acetelyne.
P.S. Homebrews link worked for me and shows the difference between R45 and R60

From the Air Gas link for those internet browsers that won't seem to follow the link.</font><font color="blue" class="small">( "RG45 is a general purpose, copper coated, gas welding rod used for welding low carbon steels up to ¼” thick. It is a great selection when ductility and machinability are most important. You do not need a flux when welding with this product."

"RG60 is a high strength alloy used for gas welding of low carbon and low alloy steels. It is used in applications where a high tensile strength is needed. The high Silicon and Manganese content in the product eliminates the need for flux when welding.")</font>
