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.
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.
