Was playing around tonight practicing on some scrap and got thinking.What are some visual/sound/obvious ways to help you dial in wire speed and heat.Any rules of thumb to go by judging by the weld that will tell you to turn up your speed, lower your speed, heat, etc?

Reply:For a given voltage setting you can watch the length of arc as the wire feed is adjusted. Too high a feed and the arc length closes and will momentarily stub on the material. At the other extreme you will notice the arc will max out until you have an unmanageable welding arc. With practice at a given voltage range such as short circuit voltage ( 19 volts) you will recognize that sweet spot/arc length. I tend to set my voltage then tune my wire speed. Others do the opposite. Once I have it close I will then tweak the voltage if I want a more fluid puddle for example.
