5.0 out of 5 stars Like the flux you used to get
Reviewed in the United States on November 4, 2021

I recently ran out of the white powdered flux I have had for years. When I went to my local welding supply store they only had a liquid flux which was terrible. They said they didn't have a powdered flux. I searched for quite a while and finally found and purchased this one. So glad I did. It works at least as good as the original. . . Maybe better. Only issue which was my fault. After you heat the rod and dip it in the flux do not forget it and leave it in the can. You will be amazed how much flux adheres to the rod.

I was having a hard time finding this stuff. Welding stores no longer carry it. Found this on Amazon. Works like the flux I used 30 years ago. It is not as powdery as the old flux, but more like salt size. Works never the less.

4.0 out of 5 stars Product good the can not so much.
Reviewed in the United States on June 16, 2021

Product is good but once I received it the package was filled with the contents of the can. The flux was easy to put back into the can but shipping powder in a small paint can is not really smart. unless it would be sealed better Small cans often take damage in shipping. As mine did.
Seller should ask the manufacturer to change package to box or bag. So it would take shipping damage belter It would help lower the cost to the manufacturer and the buyer.
But like I was saying the flux is good at welding or rather helping the metals to bond .
