- 1). Put on your personal protective equipment such as earplugs, safety glasses, welding gloves and welding helmet to protect your skin and eyes. Flux core wire requires more voltage than other forms of welding which makes it produce more light and heat.
- 2). Prepare the surface of the material you will be welding by using your chipping hammer and wire brush to clean away any oil, rust, paint or dirt to ensure you get proper penetration. Penetration is the distance below the surface your welding that metal is fused together.
- 3). Adjust the machine settings by changing the wire feed speed and voltage based on the size of the wire that you are using. On the inside door of the machine there is usually a chart which indicates what settings you should use based on the wire you have.
- 4). Pull the trigger on your welding gun and start the arc while keeping the end of the contact tip about 1 inch away from the surface you are welding. Use a travel speed which keeps the arc at the front edge of the puddle of molten metal and produces the desired weld size. The higher deposit rate with Innershield wire usually increases the travel speed over what is used in other forms of welding.
