Tips are as follows:
Set your heat range based on the thickness of the metal you're welding. That looks like about 1/8" mild steel. You'll need about 100 amps (give or take) to weld that with decent penetration. If your welder is 115v, it's probably a max of 140 amps so if it's labeled 1/4, 2/4, 3/4, 4/4 3 or 4 will work. If it's a 90 amp welder, you'll need to use the top amperage rating.
Once you've set your amperage, use the provided chart to figure a starting point on line speed. Once you've got the speed set according to the chart, you'll need to start welding. When the welder begins to weld, you'll need to have it at arms length so you can adjust/ fine tune the line speed adjustment.
You want to adjust the line speed asjustment by feel and sound. If the torch is "pushing back" against your hand you need less line speed, if the wire is sputtering and a ball forms on the end of the wire, you need more line speed.
When you've got the line speed just right, the wire will be feeding into the weld pool and it will have a nice smooth "frying bacon" sound. The closer you get the line speed, the smoother the sound will be and the cleaner the weld will be.
With a flux cored mig welder, splatter is a way of life but when the wire speed is right it will produce less splatter.
