Final answer:
To fix an electrode sticking to the base metal, adjust the arc length, calibrate the welding current, optimize the electrode angle, and use a dry and correct type of electrode. Anti-stick devices can also help by briefly increasing current to remove the stuck electrode.
Step-by-step explanation:
If the electrode keeps sticking to the base metal causing arc strikes, this could be symptomatic of several issues within the welding process, such as incorrect arc length, welding current settings, or electrode angle. Here are some ways to remedy the problem:
- Adjust the arc length: Keeping the electrode at an appropriate distance from the base metal can prevent sticking.
- Calibrate the welding current: If the current is too low, it won't heat the base metal enough to form a proper arc, causing the electrode to stick.
- Optimize the electrode angle: An incorrect angle can affect the arc quality and result in sticking.
Additionally, ensuring the electrode is dry and using the correct type for the welding process can further alleviate sticking issues. In some cases, anti-stick devices or features in welding machines can provide a quick solution by briefly increasing current to burn off the stuck electrode without damaging the electrode or the workpiece.
