Inadquate gas flow could also be a factor, but not likely if the flowmeter is showing 20CFH. Try to keep the flow set at about that amount.
Let us know how it goes. I just finished up an intro MIG course Monday night; well worth the money. I too thought I was out of gas Originally posted by hankj View Post. If you have not been snipping the end of the wire back sometimes the restrike will do that. You get a ball on the end that will take more current to melt than the wire and Check the ground and make sure they have tips in the gun.

That popcorn sound is normally caused by one or both of these items with MIG. Also, don't hesitate to play a bit with both your tap setting and your wire speed. Look inside the cover to get your ballpark setting the list inside will be the thickness of the mild steel you're working on, the size wire you're running, the wire speed and the voltage tap. Of course your material thickness and wire size are constant, but you should learn to play with your speed and your voltage.
Each welding machine has its own personality, each weldor has his or her own technique and quirks, and until you play with those two a bit, you aren't going to get satisfactory results.
And don't forget to ask your teacher for some input if you aren't able to get good end results. That's what he's there for. Going to class should be a blast that you look forward to.

The amperage is the thing that melts the wire, heats the piece, and joins them together like solid metal. You must use the right amperage settings to avoid any popping problem with MIG welding. The right amperage settings will help you avoid the popping, bad, and unstable welding. A flux core welding electrode will give you a completely different welding speed and output than a solid wire.
Here are the best hacks to stop a MIG welder from popping and getting the best output from the welding job:. The right amperage settings will allow you to avoid overburn or keeping the wire too cold.
Decide how much amperage you need and set it accordingly. To figure how much amperage you need, multiply the thickness of the metal by After getting the size correct, feed the wire, light up the material, and listen to the sound first.
Clean it if possible or change it and move onto the liner if it has any bent or somehow chucking the wire, fix it. Here are the most common and frequently asked questions about MIG welding that you should know about as well:. A bad weld can never get you the satisfaction of accomplishment you want, where the popping problem is keeping you back.
By following these steps before you start welding, you will land some rigid joints that soothes your eyes. Turn them into habits, and be sure to check the steps before you start welding with a MIG welder. Hi, I am John Romero, I am a technical expert of a welder machine.
I have been working for more than 15 years with welding machines. Now I have started a business besides my profession. Where I sell various types of welder machines. Because of my service and business, I have to face so many clients of welder machine users. As my shop is specialized in the Welder machine,.
When it comes to welding stainless steel, it gets more complicated when you have to do it with MIG welding. The faster the wire speed, the higher the amps. But in general, wire popping is usually a result of welding wire being fed into the puddle faster than it can melt in and larger chunks just flying off violently as it does eventually create enough heat to weaken the wire and pinch off. Knowing whether to adjust just the voltage, the wire speed, or a combination of the two is largely a result of experience for the professional or trial and error by the beginner.
Any given weld will require enough wire speed to form a proper sized and shaped weld and achieve penetration, so it may be advantageous to increase the voltage first to properly utilize all the wire that is being fed into the puddle instead of readjusting the wire speed. These are notoriously inaccurate and cannot account for every welding situation and can only be relied upon for a general ball park setting. In some cases, they may not even be close.
Ultimately the key to achieving proper adjustment is to make small adjustments each time without wildly swinging the adjustment from one extreme to the other. Learn more on our welding forum.
