There is already a roll of flux cored wire in the welder. Tighten the tension nut so that it offers a small amount of turning friction.
Not so tight so as to overload the wire feed motor when it needs to starts feeding the wire. Remove the protective plastic wrapper from the roll of wire already in the welder.
Use your 3 hands so it dose not unravel. Press the roller release lever up and swing it out and let the lower roller fall away downwards. Pull the welding wire and feed it into the wire guide tube passing it under the top roller.
With a little upward pressure from your finger guide the wire into wire feed tube into the MIG torch. You may feed it by hand all the way through and out through the torch head. Swing the lower roller back into place. Pressing and holding the MIG torch trigger should feed the wire continuously.
On the roller release lever there is a screw for adjusting the roller pressure on the wire. Tighten it so as the wire feeds continuously and consistently. For MIG welding you need to clean the meta l to welded quite thoroughly. Use a flap sander or a wire brush to clean it up to bare metal.
For metal with oil on it use a cloth and thinners to clean it if the sanding has done a good job. The reason we use gas is because it shields the weld puddle from the contaminents in the atmosphere that can wreak havoc on the weld appearance and strength. With DCEN, the negative terminal inside your machine is hooked up to your electrode your MIG gun while the positive terminal is hooked up to your ground.
They then travel through the workpiece and ground cable, then back to the machine. For DCEP, you now have your positive terminal hooked up to your electrode. The electrons now travel in the reverse direction from the machine through the ground cable, and back in through the MIG gun.
