Learn how to properly strike an arc when the welding arc can be quite a headache. There are several methods to strike an arc and we will discuss them here. One thing that might make even the most difficult part is that you can not see what you're doing, so I highly recommend getting an automatic welding helmet dark. It will probably be the most important investment that will make on your quest to learn how to arc weld.
The basic theory behind how to strike a simple arc. You have to make the metal of the metal electrode on the welding contact you. Then have to be pulled away from the metal about 1/4 inch. If you do not pull it away it would just stick to your job. If it happens quick twist and pull will usually get it loose. If it does not break free on your first attempt will want to squeeze the clamp on the electrode holder and pull away. Keep in mind every time the electrodes attached to your work, welders are fused. This will cause it to overheat more quickly, and can blow the fuse or breaker in your breaker box.
There are some techniques on how to strike the arc, I suggest you try them all and see which one is most comfortable for you. Remember, practice is the key to being a good welder. The first method is a method of puncture. The way this works is you position the electrode about 1/2 inches from your work. Then flip your helmet down. Now you want to quickly prick the stem into the job then immediately pulled back. Another method is the initial method. This method works very much like striking a match. Just imagine the electrodes is a match, and the location you want to express your welding bead is the striker. If you are sure to use very fast strokes you are much less likely to have a stick electrodes when using this method.
One common problem people have is that no matter what the electrode simply freezes on the job. If you experience this, most likely means that the amps need to appear on your welder. Try to change it to 10 amps at a time until it stops sticking. If you are having success getting the arc to start, but then get out, you will attract the welding rod is too far from your work. Remember, you only want to pull back about 1/4 inch.
Once your bow case, you need to immediately start feeding the electrode into it. Electrodes will burn fast enough, so you must keep at the proper distance to maintain the arc. When it is at the correct distance that would make a crunching noise. If you get too much more than sound would emerge with the sparks flying in all directions. If too close you'll see an arc starting out and it will make less noise. If the bow out after you have restarted you can weld a little easier while still molten metal. Simply attach the electrode back into the puddle of water while you still can see it shine through your mask.
Sometimes need to have the initial arc exactly the right place. It can be difficult without a helmet auto dark. One trick is to put a small piece of scotch tape on the ends of metal where you want the beads to get started. This way you can put electrodes on the tape with a helmet to the top, then drop your helmet and just drag it off the tape.
Learning how to strike the arc can be one of the most frustrating step in learning how to arc weld. Fortunately, once you get to the bottom, it becomes almost natural. Learn how to arc weld is mostly a process of practice. Get yourself some scrap metal and spent a few afternoons burning electrodes before you try to weld something important.
