Stick Electrodes For mild and low alloy steel welding.I used the thinnest solid wire (0.6mm) with mig gas, the zinc will leave a white fluffy powdery residue and as previously mentioned do not breathe in the fumes.īy vertically downwards I really do mean vertically, once it starts getting towards the horizontal the hole will collapse. I expect when you look inside the tube there will be heaps of wires inside, I used a small grinding wheel on a long shaft to remove them. If after the run is finished just go back and do the hole, still vertically. Stay too long in one spot and the weight of the weld/bead will collapse and form a bigger hole. The bead should just keep forming and traveling downwards filling / fusing in as it goes. It will probably burn through but dont worry thats what you want, just keep the arc in the middle of the bead weld and do not go side to side (weaving) Get the tubes to butt nicely, start the bead on the join and travel downwards. I would suggest the best method is to weld vertically downwards. Having mig welded a lot of thin wall steel tubing when building recumbent bicycles. What causes this? Others would have a bulge in the center or a bulge around the edges with a deeper dent in the center. Some of my tacks would be a small flat circle. How does wire speed effect the weld? Is it dependent on how thick the material is? Or how fast you are welding? Or some combination of the two. ![]() If you are tack welding would max power be better to get quick penetration without blowing a hole? Only about half of my tacks looked like they had penetrated all the way through. But what about penetration? Should I see the weld on the inside of the tubing. Intuition suggests that you should be using the min power setting when welding thin tubing. I found that it was real easy to blow a hole in the tubing no matter what the settings were.įirst question is power setting. Yet no demonstration on how different settings impacted the weld or the settings being used. All the rest mentioned adjusting the settings to suit the material. Power on max and wire speed on 5 welding exhaust tubing. Out of all of the videos I watched only one gave the settings being used. Except when the wire speed was set to 1 I didn't really notice much difference in the welding. Min and Max power and wire speeds from 1 to 5. Cleaned the conduit to bright and shiny before welding. Spent most of the afternoon watching videos on flux core welding and practicing welding electrical conduit thin wall steel tubing. I am using 030 wire that came with the machine. My HF 125 has been modified with a bridge rectifier and a capacitor so it is a DCEN welder.
