Pulling is recommended but pushing can work too. What is the right angle? Should I push or pull? The right stickout varies with wire diameter but for. What is the right stickout? ( distance from the contact tip to the arc) If your welder has no settings chart, then search google for “mig welding chart” but make sure to use the settings for gasless flux core wire and set polarity to DCEN. To get in the ball park, use the settings listed on the chart inside the door of your mig welder to get you started. Most of these are available online.įor example, here is a spec sheet for the Lincoln wire I used in this video Reputable manufacturers of self shielded flux core provide data sheets with recommend settings. How do you know what settings to use for self shielded flux core? People Also Asked these questions about self shielded flux core welding for beginners Take a minute to make sure you have a secure ground and save yourself some heartburn. When that happens, the wire stubs momentarily and can make you think you need to adjust your settings. If your ground clamp is on an area where there is mill scale, paint, rust, or other coating, you risk losing the connection intermittently. Wire fed processes like bare wire mig and flux core really need a good secure ground connection.more so than other welding processes. Stick out is usually slightly less because it refers to distance to the arc and not the work.Įither way, be careful not to use an excessively long stickout. Lincoln uses a term called CTWD which stands for contact tip to work distance. 035" NR211 flux core wire, the recommend stick out is around 5/8". what is the right stick out for flux core welding?įor. The same settings used for bare wire mig will not always work for gasless flux core. I have found that for flat and horizontal welding, these recommended settings are pretty good to get you started.īut make sure to carefully line up each column and chose the right wire type and diameter etc. Most reputable mig welding machine manufacturers put a settings chart inside of the wire feed door. Voltage and wire feed speed for flux core welding I set tension to the point where I can stop the wire feeding by pinching the wire with medium pressure. I set my tension by pinching the wire as it comes out of the contact tip with my fingers while wearing a glove. Flux core wire has flux inside and can be crushed by using too much drive roller tension. You are going to want less tension on flux core wire. How to set the right drive roller tension Knurled drive rollers work best because of the reduced tension used to feed flux core wire. Make sure to select the right drive rollers for the size wire you are using. On other machines, you have to undo bolts and switch wires inside the wire feeder cabinet. Some machines have a pigtail on the front that makes it very easy to change polarity. In bare wire mig welding, the electrode is where the mig gun is connected. Polarity in welding refers to whether your electrode is positive or negative. Trying to weld with self shielded flux core on DCEP will make you cuss. Mig welding on reverse polarity dcep works great often inside the machine, its even less apparent. That is because on many mig welding machines, switching the polarity involves switching the electrode connections.Īnd since that connection is. Since a lot of mig welders are set up to run either with bare wire mig with shielding gas…or self shielded flux core, a lot of mig welders are set to DCEP electrode positive aka reverse polarity with no knob or switch to change polarity that is obvious to a beginner. One main thing you need to know about flux core welding is that it requires the polarity to be on DCEN.
