Adjusting The Spool Position - Clarke HOT SHOT SPOOL GUN WELDER FLUXCORE/MIG 135SG Mode D'emploi

Figure 14. Changing Polarity
WARNING
Electric shock can kill! Always turn the
power OFF and unplug the power cord from
the ac power source before changing polarity.
CAUTION
Do not use a ratchet, crescent or other lever
type wrench to tighten knobs on the polarity
block. The nuts must be hand tightened only.
Too much torque applied to one of the knobs
could cause the knob to break off.
1. Remove the retaining knobs from the +
and - mounting posts on the Gas/No Gas
Board on the inside of your welder.
A. For Gasless welding, mount the
Ground Clamp ring terminal to the "+"
mounting post and the Torch ring ter-
minal to the "-" mounting post.
B. For Gas (MIG) welding, mount the
Ground Clamp ring terminal to the "-"
mounting post and the Torch ring
terminal to the "+" mounting post.
See configuration shown in Figure 14.
2. Attach the ground clamp to the work
piece, making sure that it is cleaned of dirt,
oil, rust, scale, oxidation, and paint at the
point of connection.
Note: It is best to connect the ground clamp
directly to the work piece and as close to the
weld as possible. If it is impractical to con-
nect the ground clamp directly to the work
piece, connect it to metal that is securely
attached to the work piece, but not electrical-
ly insulated from it. Make certain this other
metal is of equal or greater thickness than
that of the workpiece.
CAUTION
Risk of electric component damage! If the
ground clamp is being connected to an auto-
mobile or other equipment with on-board
computer systems, solid state electronic con-
trols, solid state sound systems, etc., do not
weld until disconnecting the battery that is
attached to the chassis ground. Failure to do
so may result in electronic component dam-
age.

ADJUSTING THE SPOOL POSITION

Before you begin welding, you may want to
adjust the position of the spool so it is most
comfortable for you. There are three posi-
tions to chose from.
To change the position of the spool:
1. With a flat tipped screwdriver, loosen
the screw which connects the spool cas-
ing to the gun.
2. Pull the casing far enough away from
the gun to allow for rotation of the cas-
ing.
3. Rotate the casing to one of the three
available positions, making sure that the
grooves on the gun are aligned with the
grooves on the casing.
4. Push the casing and the gun back
together.
5. With a flat tipped screwdriver, tighten
the screw which connects the spool cas-
ing to the gun.
