Distance From The Work Piece; Tuning In The Wire Speed - Magnum CARIMIG 202LCD Manual

Operating Instructions and Parts Manual
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.
5.2. Select a heat setting. Refer to set up chart
5.3. Hold the torch in one hand, allowing the nozzle to rest on the edge of the work piece
farthest away from you, and at an angle similar to that which will be used when welding.
(See HOLDING THE TORCH if you are uncertain of the angle at which you will be welding).
