3.02 Torch Head
ART# A-10838_AB
Figure 3-6: Torch Head
The N7500 Torch Head feeds the jointed electrodes down to the work surface. The Control Box controls and sig-
nals the motor on the Torch Head to feed or retract the electrode. This action maintains arc voltage or current, set
on the Remote Pendant. The Control Box (See “Figure 3-1: Control Box” on page 3-1) channels the DC current
from the DC Welding Power Supply to the Torch Head using standard welding cables. Compressed air coming
from the Control Box connects at the Torch Head with a 3/8” NPT female pipe elbow.
