Operating Instructions
1. Connect the ground clamp to a scrap piece of the same
material as that of the workpiece to be welded.
Note:
The thickness of the scrap piece should be equal to
or greater than the thickness of the actual workpiece, and
free of oil, paint, and rust.
2. Select the heat setting.
3. Hold the torch in one hand, and allow the nozzle to rest
on the edge of the workpiece farther from the user and
at a desired angle for welding. There are two angles of
the torch nozzle in relation to the workpiece that must be
considered when welding.
Angle A
60
fig N
JM-1998594-18
• 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 workpiece). If angle A is
increased, penetration will increase, and if it is decreased
penetration will decrease (fig N).
Angle B
30
45
fig O
JM-1998594-19
• Angle B can be varied to improve the visibility of the arc
in relation to the weld puddle and to direct the force of
the arc (fig O).
4. Turn the wire speed adjustment knob with the other hand
to its maximum position and continue to hold onto the
knob.
5. Pull the trigger (1) on the torch to start an arc. Drag the
torch towards the user while simultaneously turning the
wire speed adjustment knob counter-clockwise (fig P)

6. When the wire speed decreases, the sound that the arc
makes will change from a sputtering sound to a high-
pitched buzzing sound. The correct setting is the point
where the high-pitched buzzing sound is achieved.
Use the wire feed control to slightly increase or decrease
the heat and penetration by selecting higher or lower wire
feed settings. Repeat this tune-in procedure if a new heat
setting, a different diameter wire, or a different type of
welding wire is selected.
Note:
Clean the base material using chipping hammer/
wire brush combination (1) before you start welding and
between each welding pass to avoid contaminants that
lead to poor welds (fig Q).
