WELDING TORCHES AND ACCESSORIES
The welding torch guides the wire and
shielding gas into the weld zone. It also brings welding power to the
wire. Different types of welding torches
have been designed to provide maximum welding utility for different
types of applications. They range from
heavy duty torches for high current work to lightweight torches for low
current and out-of-position welding.
In both types, water or air cooling and curved or straight front ends are
available. Figure
2-2 shows a cross-sectional view of a typical air cooled, curved front end torch
with these necessary accessories:
a. contact tube (or tip)
b. shielding gas cup or nozzle
c. wire conduit and liner
d. one-piece composite cable
