11.4 Position of MIG Torch
The angle of MIG torch to the weld has an effect on the width of the weld. The welding torch should be
held at an angle to the weld joint. (See Secondary Adjustable Variables below). Hold the torch so that the
welding seam is viewed at all times. Always wear the welding helmet with proper filter lenses and use the
proper safety equipment.
CAUTION! Do not pull the welding torch back when the arc is established. This will
create excessive wire extension (stick-out) and make a very poor weld.
The welding wire is not energized until the torch trigger switch is depressed. The wire may therefore be
placed on the seam or joint prior to lowering the helmet.

11.5 Distance from the MIG Torch Nozzle to the Work Piece
The welding wire stick out from the MIG Torch nozzle should be between 10mm to 20mm. This distance
may vary depending on the type of joint and type of wire that is being welded. Generally solid wire is about
10mm and flux-cored/gasless wire about 15-20mm.
11.6 Travel Speed
The speed at which the molten pool travels influences the width of the weld and penetration of the welding
run.
