A welding apparatus includes a welding electrode, where the welding electrode has a concavely formed end-face region and where the welding electrode has a magnet such that a spherical dome-shaped portion of a magnetically attractable ball which is located in an effective range of the magnet is drawable against the concavely formed end-face region.

Apparatuses, systems, and/or methods relate to a welding system that provides a field former for use in welding applications. The welding system includes a welding torch that includes one or more coil windings through which flows current that forms a magnetic field. The magnetic field is concentric to the tool center point. An arc is formed between the electrode and a workpiece. The magnetic field forces the arc in a center of the welding torch or the one or more coiled windings.

Methods and apparatus to synergically control a welding-type output during a welding-type operation are disclosed. An example welding-type power supply includes a power conversion circuit configured to convert input power to welding-type power and to output the welding-type power to a welding-type torch; a communication circuit configured to receive a control signal from a remote control device during a welding-type operation; and a control circuit configured to synergically control a voltage of the welding-type power and a wire feed speed based on the control signal.
