Hello, I apologize for your experience with Bernzomatic and the inconvenience it has caused with your project. That is certainly not how our product should have performed. I would recommend checking out our article on brazing metal for additional support: https://www.bernzomatic.com/Community/Projects/Build/Braze-Metal-Together
We take all reviews seriously and investigate each case so we can continue to improve our products. If you have not already returned or exchanged your torch we would appreciate you contacting us at: Bernzomatic@WorthingtonIndustries.com or at 1-614-438-7907. Thank you.
