- Page 44 10.1 Basic MIG Welding Good weld quality and profile depend on factors like gun angle, travel direction, electrode extension (stick out), feeding speed, base metal thickness, wire feed speed (amperage), and arc voltage. Here are some basic guidelines to help with your setup: Gun Position and Travel Direction ...
- Page 45 Figure 56 Angle to Work The work angle is the forward back angle of the gun relative to the work piece.The correct work angle provides good bead shape, prevents undercut, uneven penetration, poor gas shield and poor quality finished weld.
- Page 46 10.2 Feeding Speed Feeding speed refers to how quickly the gun is moved along the weld joint, measured in inches per minute. It can vary based on conditions and the welder's skill, limited by their ability to control the weld pool.
