A. Arc welding is widely used in various industries due to its simplicity and versatility. For a new welder,the most frustrating step in arc welding is learning how to strike an arc weld. The good news is that once you learn,it becomes second nature.
Step 1 Buy a welder with the correct amperage for the thickness of metal you are intending to weld.
Step 2 Practice striking beads of weld on a piece of steel plate. Do this on two plates, both sides each. Arc welding is a process that involves practice. You may need to burn up to 15kgs 40 lbs of electrodes to become proficient in striking an arc.
Step 3 Position the electrode approximately 12mm inch away from the piece you want to weld and flip down your helmet. Jab the electrode quickly into the work and immediately pull it back. This is the method used to strike the electrode.
Step 4 Strike the electrode against your work, known as the work piece, to make a weld. Make sure that the stroke is quick so the rod doesnt freeze to the work.
Step 5 Turn up the amperage if the rod freezes to the metal youre working on. Increase the amps by 10amps at a time until the freezing stops.
Step 6 Pull the welding rod back about 6mm inch only. This will prevent the electrode from going out once you strike the arc.
Step 7 Listen for a crackling noise to indicate that youre keeping the electrode at the correct distance. A popping noise with sparks means that its too far away. If you keep it too close, it will extinguish the arc will start to go out and youll hear less noise.
Step 8 Stick the electrode back into the puddle if the arc goes out after youve started welding.
