Save money and time when you weld without purging.

Solar Flux

The unique welding backup flux, SOLAR FLUX is a complex chemical compound in the form of a very fine powder. When mixed with alcohol and brushed on the back of the weld joint, SOLAR FLUX is formulated to shield the BACK of the weld joint from oxygen, dissipate heat and unwanted oxides, and to clean the surface of the metal. SOLAR FLUX aids in the flow of filler metal over base metal and forms a protective barrier to prevent re-oxidation and heat scale.

SOLAR FLUX is available in two types:

For fusion welds
For every type of joint
By all arc and gas welding methods
