Sorry about the delay, as I don't check this forum often. The website for welding rods: https://weldingsupply.securesites.com/cgi-bin/einstein.pl?Next::1:UNDEF:OR:terms::PF

The ones I purchased were "house brand" and the number is
RG45322. This is the page where they are listed to order from, so you won't have to search \:\)

Hope this helps.
