## Overview

The HARRISS0FB01 Type B Solar Welding Flux is a 1 lb. can designed to provide superior protection for weld joints by shielding them from oxygen, ensuring optimal weld quality. Its compact size and lightweight design make it a convenient choice for professionals on the go.

## Description

Solar flux is a complex chemical compound in the form of a very fine powder. Solar flux is mixed with alcohol (methanol/methyl alcohol preferred) and brushed on the weld joint. It 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. It will aid in the flow of filler metal over base metal and form a protective barrier to prevent re-oxidation and heat scale.

## Questions & Answers

**Q: Can this be used with a flux cored mig welder.**
A: This can be used on any metal except high-nickel alloys like inconel.  It's mostly used for stainless TIG projects but there's no reason you could not use it to back up other processes as well.  It can be difficult to remove so it's not suitable for food piping, but it works very well for less critical applications like stainless exhaust systems.

**Q: Is it adhesive? Or it should used with other adhesive product?**
A: This is not an adhesive. It is a  product you mix with alcohol to make a brushable  paste you brush onto the back of a stainless steel seam prior to tig welding to keep the oxygen from causing oxidation.

**Q: Can this be used when mig &/or tig welding 304-to-304 and 304-to-409 stainless steel?**
A: Yes, I specifically purchased to apply on the backside of exhaust welds on a 409 system. 
I was tig welding butt connections and it made a big difference. Also welded 304 clamp collars onto the 409 tubes. Worked great. 
Search YouTube for more info. That’s how I found out about this product. Mixed it into a paste and applied to back of weld areas.

**Q: I'm Oxy/Acetylene welding stainless (gas welding is fun for me), is this flux suitable for the front side of the joint as well?**
A: I presume you wouldn't need it as the stream of burning gas should displace oxygen from the pool as it does with mild steel. It may also contaminate the weld pool if you put it way of the welding operation as they say when you think it is clean then clean it again! It dries on the back to prevent the back oxidising thus maintaining the great anti corrosion property of stainless steel. I use tig but imho it is no way as good as a back purge of argon but you could possibly get away with it for a non critical non commercial job. I hope that helps.

## Customer Reviews

### ⭐⭐⭐⭐⭐ What you want to weld 304 316 321 stainless steel
*by G***V on November 17, 2018*

Got here quick, great price, this is what you want to use to weld 30x 304 316 321 stainless steel exhaust with tig or any use case where you dont want to have to run a back side purge to protect against back side carbide precipitates. I mix it with heat, the stuff you can pick up at any automotive store to keep fuel from freezing. It is methanol and what is the recommended to mix with the solarflux. Make it into a paste, on the thin side like olive oil consistancy, not super runny but also not stiff like tooth paste. It will harden up as it sits after you have mixed it. You just need to add more methanol or heat to thin it. If you have extra just keep it. It will dry and you can just add the heat and thin it out again. I use an acid brush. Works well. Before you weld make sure it has fully dried out.

### ⭐⭐⭐⭐⭐ Works great
*by G***N on June 27, 2022*

Much cheaper (if messier) than back purging. Excess cleaned off easy, interior welds are 95% as good as with 100% argon back purge on stainless headers. Also, a little goes a long way. Once the alcohol evaporates, you can re wet it and mix it back up, never noticed a difference.

### ⭐⭐⭐⭐ Nice secondary way of back purging for welding stainless steel.
*by A***R on December 22, 2019*

For welding stainless steel, when you feel welding with purging gas inside of the pipe is a little too lavish or complicated shape, this one works good. Solar flux prevents the back of the material from oxidized.
