MMA Welding Machine: What is Hot Start, Arc Force & Anti-Stick?

Hot Start
Hot Start is a special feature for MMA (stick-electrode) welding where the machine delivers a peak of current when striking the arc. This is important as it significantly increases the ease of starting electrodes, especially in difficult conditions such as damp electrodes, imperfect job surface, or when using ‘difficult to run’ electrodes, etc

Anti-Sticking
Arc Force, sometimes called "Dig" or "Arc Control", is a similar feature to Hot Start, except Arc Force operates during welding, not just at ignition. When the welding machine senses a short circuit it will deliver a peak of current. This greatly assists in stabilizing the arc, preventing the arc from cutting out while welding and preventing electrode sticking.

Arc Force
Anti-Stick allows the stick welding electrode to be easily detached, if it does begin to stick to the job. When the machine senses that the electrode is sticking, it will collapse the welding current to stop the electrode from continuing to weld itself to the job, allowing it to break free easily.

All of them help against one of the disadvantages of stick welding, which is sticking the electrode.
1.Hot start increases the amperage when striking an arc.
2.Arc force increases the amperage when shortening the arc length.
3.Anti stick cuts off the current when the rod sticks to the base metal.
