What is Hot Start, Arc Force & Anti-Stick?

What is 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. What is Arc Force ? Arc Force, sometimes called 'Dig' or 'Arc Control', is a similar feature to Hot Start, except Arc Force operates
