Turn off all equipment when not in use.
Do not use worn, damaged, undersized, or repaired cables.
Do not drape cables over your body.
If earth grounding of the workpiece is required, ground it directly with a separate cable.
Do not touch electrode if you are in contact with the work, ground, or another electrode from a different machine.
Do not touch electrode holders connected to two welding machines at the same time since double open-circuit voltage will be
present.
Use only well-maintained equipment. Repair or replace damaged parts at once. Maintain unit according to manual.
Wear a safety harness if working above floor level.
Keep all panels and covers securely in place.
Clamp work cable with good metal-to-metal contact to workpiece or worktable as near the weld as practical.
Insulate work clamp when not connected to workpiece to prevent contact with any metal object.
Do not connect more than one electrode or work cable to any single weld output terminal. Disconnect cable for process not in use.
Use GFCI protection when operating auxiliary equipment in damp or wet locations.
SIGNIFICANT DC VOLTAGE exists in inverter welding power sources AFTER removal of input power.
Turn Off inverter, disconnect input power, and discharge input capacitors according to instructions in Maintenance Section before
touching any parts.
Do not touch hot parts bare handed.
Allow cooling period before working on equipment.
To handle hot parts, use proper tools and/or wear heavy, insulated welding gloves and clothing to prevent burns.
Welding produces fumes and gases. Breathing these fumes and gases can be hazardous to your health.
Keep your head out of the fumes. Do not breathe the fumes.
If inside, ventilate the area and/or use local forced ventilation at the arc to remove welding fumes and gases. The recommended way
to determine adequate ventilation is to sample for the composition and quantity of fumes and gases to which personnel are
exposed.
If ventilation is poor, wear an approved air-supplied respirator.
Read and understand the Safety Data Sheets (SDSs) and the manufacturer’s instructions for adhesives, coatings, cleaners,
consumables, coolants, degreasers, fluxes, and metals.
Work in a confined space only if it is well ventilated, or while wearing an air-supplied respirator. Always have a trained watch-person
nearby. Welding fumes and gases can displace air and lower the oxygen level causing injury or death. Be sure the breathing air is
safe.
Do not weld in locations near degreasing, cleaning, or spraying operations. The heat and rays of the arc can react with vapors to
form highly toxic and irritating gases.
Do not weld on coated metals, such as galvanized, lead, or cadmium plated steel, unless the coating is removed from the weld area,
the area is well ventilated, and while wearing an air-supplied respirator. The coatings and any metals containing these elements can
give off toxic fumes if welded.
Arc rays from the welding process produce intense visible and invisible (ultraviolet and infrared) rays that can burn eyes and skin. Sparks fly off
from the weld.
Wear an approved welding helmet fitted with a proper shade of filter lenses to protect your face and eyes from arc rays and sparks
when welding or watching (see ANSI Z49.1 and Z87.1 listed in Safety Standards).
Wear approved safety glasses with side shields under your helmet.
Use protective screens or barriers to protect others from flash,glare and sparks; warn others not to watch the arc.
Wear body protection made from durable, flame−resistant material (leather, heavy cotton, wool). Body protection includes oil-free
clothing such as leather gloves, heavy shirt, cuffless trousers, high shoes, and a cap.
ARC RAYS can burn eyes and skin.
FUMES AND GASES can be hazardous.
