To shut off the torch simply release the control switch. When the switch is released a ten second
post-flow will occur. If the torch switch is closed during the post-flow, the cutting arc will restart
immediately when the torch is brought within range of the workpiece.
B. Piercing with a Hand Torch
√ √ √ √ √
When piercing with a hand torch, tip the torch slightly so that blowback particles blow away from the
torch tip (and operator) rather than directly back into it.
√ √ √ √ √
Complete the pierce off the cutting line and then continue the cut onto the line. Hold the torch
perpendicular to the workpiece after the pierce is complete.
√ √ √ √ √
Clean spatter and scale from the shield cup and the tip as soon as possible. Spraying or dipping the
shieldcup in anti-spatter compound will minimize the amount of scale which adheres to it.
WARNING
Disconnect primary power at the source before disassembling the torch or torch leads. Frequently review
the Important Safety Precautions at the front of this Manual. Be sure the operator is equipped with proper
gloves, clothing, eye and ear protection. Make sure no part of the operator's body comes into contact with
the work -piece while the torch is activated.
CAUTION
Sparks from the cutting process can cause damage to coated, painted, and other surfaces such as glass,
plastic and metal.
NOTE Handle torch leads with care and protect them from damage.
TORCH CONSUMABLE PARTS SELECTION
