SET UP AND WELDING

With the correct stud and ferrule to be welded fitted
into the chuck/ferrule grip, loosen the thumbscrews
and slide the foot assembly until the stud is
protruding past the ferrule to the desired distance.
Once this is set, re
-
tighten the thumbscrews.
Remove the ferrule and check the centrality of
the stud in the ferrule grip by looking straight
down the centre of the pistol shaft. If the stud
appears to be off
-
centre. Use a 3mm hex key to
loosen the foot screws on the foot adaptor and
re
-
position the adaptor on the legs (the holes in
the adaptor are designed to allow adjustment).
Re
-
tighten the screws once the adjustment has
been made.
The next step is to set the required lift for
welding. This must be done in three stages to
ensure that the lift is set properly. Stage one is
to back the lift off so that the pistol can be
properly positioned to set the lift. To back the
lift off, twist the rear end cap adjuster anti
-
clockwise until the pistol indicator is in the MAX
position.
Stage two is to
“
zero
”
the lift. NOTE Ensure that the pistol is not connected to the
controller whilst performing this stage. To do this the pistol (with a
stud and ferrule loaded) needs to be pressed into the position as if a
weld is about to take place with the shaft moving back until the
ferrule is hard against the surface. With the pistol held firmly in this
position, turn the rear end cap adjuster clockwise and continue to
turn it until it reaches the zero position. This is the point where
further turning of the adjuster will start to force the stud forward,
lifting the ferrule away from the surface. This is the zero position.
