Select the right stickout (free wire protrusion) for your welding task to avoid seam defects that can be caused by an unfavorable torch position.
The optimum stickout depends on the process used, wire diameter and component geometry. A stable torch position is a prerequisite for uniform penetration depth and seam formation. This is often influenced by the preparation and accessibility of the component.
In forced welding positions - e.g. overhead or vertical seams - particular attention must be paid to correct welding parameters (current, voltage, wire feed) and sufficient gas coverage in order to avoid arc instability or pore formation.
