HOW TO: IMPROVE YOUR STICK WELDING TECHNIQUE Stick welding (or shielded metal arc welding) can be a hard process to learn as there is an array of issues that could cause problems. But don’t despair. There are techniques that can make the process easier. Known as CLAMS – Current setting, Length of arc, Angle of electrode, Manipulation of electrode and Speed of travel – these procedures are straightforward to learn, will improve the weld and ensure the job is completed properly according to the Welding Industries of Australia. However, before laying down these techniques, the surface has to be prepared properly, which includes making sure that the workspace is clean. It also means that the surface of the metal being welded must be grit-, dirt- and rust-free. If it is not, the weld will probably crack, which means the job will be ruined and the only option will be to start again. Positioning of the body is a key consideration, too, as well as keeping clear of the smoke produced by the weld and having a good view of the weld puddle. 16 June 2017 CURRENT SETTINGS The selected electrode will determine whether a machine should be set up in AC, DC negative or DC positive. It is best to select the amperage being used based on the electrode, welding position and visual inspection of the finished weld. If the finished weld is poor, then one of these settings could be the problem. It is important to adjust the welder by 5 to 10 amps at a time, until a suitable setting is found. If the amperage is too low, the LENGTH OF ARC A good rule of thumb is that a correct arc length will not exceed the diameter of the core of the electrode. Using a long arc seems natural because it helps the user see the arc and puddle. However, the user should position themselves so they have a better view of the arc. If a user’s body is put in the correct position, it not only gives a good view of the puddle it also helps to manipulate the electrode correctly. electrode will start sticking when striking an arc. If the amperage is set too high, glitches can appear that include the puddle being excessively fluid, the electrode charring when half of it is gone and an arc sounding louder than it should. Excessive heat can also have a negative affect the electrode’s flux abilities. WELDING FEATURE
