OPERATION FIREPOWER 160 S
Manual 0-5371 4-7 Operation
12. The tungsten must be ground to a blunt point in or-
der to achieve optimum welding results. It is critical
to grind the tungsten electrode in the direction the
grinding wheel is turning.
NOTE
About tungsten selection for this power
supply, a 2% Thoriated tungsten is generally
used for DC straight polarity welding. Point
the tungsten by grinding a taper on it about
2½ times the diameter of the tungsten used
and grind a slight flat on the end, this will
help stabilize the arc.
13. Install the tungsten with approximately 1/8” to ¼”
sticking out from the gas cup, ensuring you have
correct sized collet.
14. Tighten the back cap then open the valve on the
torch.
15. You are now ready to begin TIG Welding.

1. Before opening the cylinder valve, turn the
regulator adjusting screw counter-clockwise
until there is no pressure on the adjusting spring
and the screw turns freely.
!
WARNING
Stand to the side of the cylinder opposite the
regulator when opening the cylinder valve.
Keep the cylinder valve between you and the
regulator. For your safety, NEVER STAND
IN FRONT OF OR BEHIND A REGULATOR
WHEN OPENING THE CYLINDER VALVE!
2. Slowly and carefully open the cylinder valve
(Figure 4-9) until the maximum pressure shows
on the high pressure gauge.

3. On all cylinders, except acetylene, open the
valve completely to seal the valve packing. On
gaugeless regulators, the indicator will register
the cylinder contents open.
4. Attach the desired downstream equipment.
