Attributes such as material thickness, welding position, electrode diameter, surface condition, welding procedures and others can affect results. Limited to short circuit and globular transfer. Limited to short circuit and globular transfer. Can be used in short circuit, globular, pulse and spray transfer. Can be used in short circuit, globular, pulse and spray transfer.
Most welders tend to make a weld that is too big - leading to potential burnthrough problems.
A smaller diameter wire welds more stable at a lower current which gives less arc force and less tendency to burn through. If you keep your weld current lower, you will have a greater chance of success on thinner materials. Whenever a change like this is made, always verify the quality of the weld meets its intended application. In arc welding, an arc is established from the electrode to the workpiece. To do this properly, the arc requires a smooth flow of electricity through the complete electrical circuit, with minimum resistance.
