3. Position the torch to the work piece
There are two angles of the torch nozzle in
relation to the work piece that must
be considered
when welding.
3.1. Angle A can be varied, but in most cases the optimum angle will be 60
degrees, the point at which the torch handle is parallel to the work piece. If angle
A is increased, penetration will increase. If angle A is decreased, penetration will
decrease also.
3.2. Angle B can be varied for two reasons: to improve the ability to see the arc in
relation to the weld puddle and to direct the force of the arc.
4. Distance from the work piece
If the nozzle is held off the work piece, the distance between the nozzle and
the work piece should be kept constant and should not exceed 1/4 inch or the arc
may begin sputtering, signaling a loss in welding performance.
5. Tuning in the wire speed
This is one of the most important parts of MIG welder operation and must be
done before starting each welding job or whenever any of the following variables
are changed: heat setting, wire diameter, or wire type.
EXPOSURE TO A WELDING ARC IS EXTREMELY HARMFUL TO THE EYES
AND SKIN!
Prolonged exposure to the welding arc can cause blindness and burns.
Never strike an arc or begin welding until you are adequately protected.
Wear flameproof welding gloves, a heavy long sleeved shirt, trousers with
no cuffs, high topped shoes, and an ANSI approved welding helmet.
5.1. Connect the Ground Clamp to a scrap piece of the same type of material
which you will be welding. It should be equal to or greater than the thickness of
the actual work piece, and free of oil, paint, rust, etc.
