MIG 140 INVERTER WELDER 058-9305-6
MIG welding operation
Holding the welding torch (MIG gun)
• Before starting the welding operation, try holding the torch in different positions until you
identify a suitable position.
Positioning the torch on the work piece
There are two angles of the torch nozzle in relation to the work piece that must be considered when
welding.
DANGER!
Potential hazard that will result in serious injury or loss of life.
• Consult a qualified electrician for proper installation of the electrical outlet.
• Make sure the welder is properly grounded. If not, contact a qualified
electrician for all electrical connections. Failure to comply will result in electric
shock.
• Do not cut off the grounding prong or alter the welder’s power plug in any way
and do not use any adapters between the welder’s power cord and the
electrical outlet.
• Make sure the power switch is turned OFF before connecting the power cord to
a properly grounded 120 V AC, 60Hz, single phase,16 A power source.
Angle A (60 degrees) Angle B (30-45 degrees)
• Angle A is the angle between the nozzle
and the work piece and 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, and if it is decreased penetration
will decrease
(fig V)
.
• Angle B is the angle between the
perpendicular of the work piece and the
nozzle and can be varied to improve the
visibility of the arc in relation to the weld
puddle and to direct the force of the arc
