SAFETY
Instant-On Torches
Plasma arc comes on immediately when the torch
switch is activated.
A PLASMA ARC CAN CAUSE INJURY AND BURNS
The plasma arc will cut quickly through gloves and
skin.
• Keep away from the torch tip.
• Do not hold metal near the cutting path.
• Never point the torch toward yourself or others.
Eye Protection
Plasma arc rays produce intense
visible and invisible (ultraviolet and infrared) rays that
can burn eyes and skin.
• Use eye protection in accordance with applicable
national or local codes.
• Wear eye protection (safety glasses or goggles with
side shields, and a welding helmet) with appropriate
lens shading to protect your eyes from the arc’s
ultraviolet and infrared rays.

ARC RAYS CAN BURN EYES AND SKIN
Skin Protection
Wear protective clothing to protect
against burns caused by ultraviolet light, sparks and
hot metal.
• Gauntlet gloves, safety shoes and hat.
• Flame-retardant clothing to cover all exposed areas.
• Cuffless trousers to prevent entry of sparks and
slag.
• Remove any combustibles, such as a butane lighter
or matches, from your pockets before cutting.
Cutting Area
Prepare the cutting area to reduce
reflection and transmission of ultraviolet light:
• Paint walls and other surfaces with dark colors to
reduce reflection.
• Use protective screens or barriers to protect others
from flash and glare.
• Warn others not to watch the arc. Use placards or
signs.
Work Cable
Attach the work cable securely to the
workpiece or the work table with good metal-to-metal
contact. Do not connect it to the piece that will fall
away when the cut is complete.
Work Table
Connect the work table to an earth
ground, in accordance with appropriate national or
local electrical codes.
GROUNDING SAFETY
Input Power
• Be sure to connect the power cord ground wire to
the ground in the disconnect box.
• If installation of the plasma system involves
connecting the power cord to the power supply, be
sure to connect the power cord ground wire
properly.
• Place the power cord's ground wire on the stud first,
then place any other ground wires on top of the
power cord ground. Fasten the retaining nut tightly.
• Tighten all electrical connections to avoid excessive
heating.
