3.3 CUTTING OPERATION
The sparks from the cutting process can cause damage to
coated, painted or other surfaces such as glass, plastic, and
metal.
Check torch parts. The torch tip must correspond with
cutting operation and selected current range. The torch
electrode must correspond with cutting mode (air or
multi-gas). See Tip and Electrode Selection, page 16.
Be sure the operator is equipped with proper gloves,
clothing, eye and ear protection and that all precautions at
the front of this manual have been followed. Make sure
no part of the operator’s body comes in contact with the
workpiece when the torch switch is pressed.

OPERATION
WARNING
Disconnect primary power to the system before
disassembling the torch, leads, or power supply.
1. The hand torch should be held in both hands for mak-
ing long cuts. Choose the method that feels the most
comfortable and works the best. Use the thumb to
actuate the control switch on the torch handle.
2. To positively locate the line of the cut, position the torch
over the workpiece, resting the front edge of the shield
cup on the edge where the cut is to start.
3. Lower the welding helmet. Press and hold the torch
control switch. After a two second gas purge, the pilot
arc will start. The pilot arc will stay on as long as the
torch control switch is held.
