Excelente

Works well and easy to use.

Worked on copper and galvanized steel air propane with good benzomatic torch, better flow with Hobart brazing flux granuals and with air acetylene torch. Fine for smaller copper on copper joining. Almost no flow on copper to stainless steel even with flux with these torches. Not as nice flow as brazing with some silver in the filler rod. Likely able to work with 1 in and larger with oxygen and flux.

Good purchase

Exelente para mi trabajo a un buen precio

Works as expected.

Don’t expect to melt it and blend it if you only have propane . This needs oxígen and acetylene to get it hot enough

Good to go

Good item for welding the copper line on the fridge and freezer.

I got these for copper brazing and they work great, and with no need for adding flux.
