We continue to get tons of questions on some of the basics of Flux Cored Welding. The two most popular questions we get are:
Q → I get excessive splatter and popping when I try to weld in FCAW mode, what am I doing wrong?
A → First off, lets be clear; there will always be more spatter and popping in FCAW than there is in solid wire MIG welding. It is simply the nature of the process. However, if you are REALLY getting an excess amount, you probably forgot to switch your polarity. FCAW, unlike MIG, is performed in DCEN. So switch your ground and electrode and you will likely fix the problem.
Q → Why do my welds look like crap?
A → Well, assuming that it isn’t welder induced crap, the FCAW process produces a slag (and smoke) covering that don’t look all that aesthetically pleasing. Take a wire wheel to it and it cleans right up.
In this video we are going to show you the proper welding technique to get better looking and stronger flux cored welds. We will go over:
→ Setting drive roll tension
→ Changing the polarity
→ Torch angle
→ What to look for under the hood
