Use gas shielded mig welding instead of flux core.
How to weld thin sheet metal with flux core.
Https amzn to 37bevj1 while wire feed welding sheet metal go for short bursts of welding instead of a going on a long bead.
It s not ideal to use flux cored processes for very thin below 20 gauge materials.
Revolution of flux core before 1950 the common welding use for thin metals was shielded metal arc welding smaw in the mid 1950s the development for flux core welding was achieved.
But keep in mind that thinner material like sheet metal should not be welded with flux cored wires.
How to weld steel with a flux cored welder.
Instead this self shielded flux cored process is ideal for welding dense portions of steel materials.
For sheet metal i use ine welding wire and it is just as good as their flux cored wire if you want you can grab one here.
I use the method flux core to weld thin metals as the cabinets and steel wardrobes are made from thin metals.
Flux cored arc welding fcaw this is another option for welding a 20 gauge metal sheet but does not work as well as the mig.
It is essential that you are already familiar with working with metal such as cutting it and are aware of the safety.
It s important to know that flux core arc welding fcaw is different from shielded metal arc welding smaw and mig welding techniques.
This guide will teach you how to weld steel with a flux core welder.
For thin sheet metal use argon 2 oxygen shielding gas as this will further reduce the arc heat input.
Fcaw shouldn t be used on materials thinner than 3 32 or 12 gauge.
