Hot start/arc force/anti-stick

Advaced inverter welders come with hot start, arc force, and anti-stick features. These features are benefit for both beginners and more experienced welders.

What is hot start in welding?

It is a built-in device function which produces a boost to the output voltage on the welding start and eases electric arc ignition.

When we start welding initially, the base metal is cool and most of initial heat get easily dissipated in base metal. Difficult arc striking, sticking the rod, and low penetration occur when striking the arc.

Hot start supports the function that pumps up the amperage for a short time when you start the arc. Higher amperage helps to start the arc easier without sticking the electrode to the base metal. It allows for an excellent start to welding by providing higher heat at the weld start, resulting in improved arc stability and good fusion between base metals. Hot start also helps to warm the base metal fast to achieve deep penetration at the bead’s starting point.

What is arc force in welding?

Arc force is a feature that senses the drop of the arc’s voltage caused by arc length shortening. Arc force compensates for the voltage drop by increasing the amperage. Increased amperage ensures that the heat stays the same and that the electrode will not stick to the base metal.

It is an automatic temporary voltage-current adjustment system, which can improve weld quality, reduce the chance of burn through and maintain excellent welding arc performance.

The system helps to provide constant arc force during the entire welding process and also compensates for changes in welding current-voltage, by automatically increasing current when necessary.

Arc force works by detecting the arc length when the arc starts to become short and then applying more voltage so that it will remain constant. This helps to ensure a smoother weld. Additionally, this technology can help reduce spatter in finished welds, resulting in better overall quality.

What is anti-stick in welding?

Anti-Stick feature in welding is an important safety measure that prevents welding rods from sticking to the workpiece.

Anti stick is a feature that will take action when the electrode sticks to the base metal. It will detect the short circuit and automatically cut the current. This prevents the electrode from turning red-hot and the welding machine from overloading.

This inbuilt feature can be extremely useful in preventing damage to both the welding rod and workpiece, as well as reducing downtime during operations.

Conclusion

Hot Start, Arc Force, and Anti-Stick are all features of modern welding machines that improve the quality of welds.

Hot Start improves welding startability and can help to reduce the risk of weld fusion at start of- welds.

Arc force helps to maintain a constant arc length for superior arc performance and weld quality.

Anti-stick prevents electrodes from sticking to the workpiece and prevent damaging the welding machine and weld quality.
