WeldproSafety
Thank you for using Weldpro arc welding and cutting equipment.
We ask you to work like a weld-pro and weld-pros weld and cut safely. Please read and comply with the sample safety
procedures outlined in this guide and the equipment Owner's Manual.
Always read and follow the Owner's Manual, the safety labels on the product, and all applicable safety
standards, especially ANSI Z49.1, Safety in Welding, Cutting, (we recommend you get a copy and keep it
handy).
Only qualified persons should install, operate, maintain, and repair this equipment. A qualified person is defined
as one who, by possession of a recognized degree, certificate, or professional standing, or who by extensive
knowledge, training and experience, has successfully demonstrated the ability to solve or resolve problems
relating to the subject matter, the work, or the project and has received safety training to recognize and avoid
the hazards involved.
Thank you for working safely.

1. General Safe Practices
Become trained and read the instructions before
working on the machine or welding or cutting. Read
and understand the Safety Data Sheets (SDSs) and
the manufacturer's instructions for adhesives,
coatings, cleaners, consumables, coolants, de-
greasers, fluxes, and metals.
Wear approved safety glasses with side shields under your welding helmet or face shield
and at all times in the work area.
Read and follow all labels and the Owner's Manual carefully before installing, operating, or
servicing unit. Read the safety information at the beginning of the manual and in each
section.
Wear a safety harness if working above floor level. Keep children away from all equipment
and processes.
Do not install or place machine on or over combustible surfaces.
Use GFCI protection when operating auxiliary equipment in damp or wet locations.
Use only genuine replacement parts from the manufacturer.
Perform installation, maintenance, and service according to the Owner's Manuals, industry
standards, and national, state, and local codes.
2. Arc Welding Hazards
Electric shock from welding electrode or wiring can kill.
Wear dry, hole-free insulating gloves and body protection. Do not touch electrode with
bare hand. Do not wear wet or damaged gloves.
Do not touch live electrical parts.
Do not use AC weld output in damp, wet, or confined spaces, or if there is a danger of
falling.
Use AC output ONLY if required for the welding process.
If AC output is required, use remote output control if present on unit. Do not use worn,
damaged, undersized, or repaired cables.
Additional safety precautions are required when any of the following electrically hazardous
conditions are present: in damp locations or while wearing wet clothing; on metal
structures such as floors, gratings, or scaffolds; when in cramped positions such as
sitting, kneeling, or lying; or when there is a high risk of unavoidable or accidental contact
with the workpiece or ground. For these conditions, use the following equipment in order
presented: 1) a semiautomatic DC constant voltage (wire) welder, 2) a DC manual (stick)
welder, or 3) an AC welder with reduced open-circuit voltage.

Protect yourself from electric shock by insulating yourself from work and ground. Use
non-flammable, dry insulating material if possible, or use dry rubber mats, dry wood or
plywood, or other dry insulating material big enough to cover your full area of contact with
the work or ground and watch for fire.
Disconnect input plug or power before working on machine. Do not make input
connections if color blind.
Frequently inspect input power cord and ground conductor for damage or bare wiring –
replace immediately if damaged – bare wiring can kill. Keep cords dry, free of oil and
grease, and protected from hot metal and sparks. Be sure input ground wire is properly
connected to a ground terminal in disconnect box or receptacle.
Properly install, ground, and operate all equipment according to its Owner's Manual and
national, state, and local codes.
Breathing welding fumes can be hazardous to your health.
Keep your head out of the fumes. Do not breathe the fumes. Use enough ventilation,
exhaust at the arc, or both, to keep fumes and gases from your breathing zone and the
general area. The recommended way to determine adequate ventilation is to sample for the
composition and quantity of fumes and gases to which personnel are exposed.
Read and understand the Safety Data Sheets (SDSs) and the manufacturer's instructions
for adhesives, coatings, cleaners, consumables, coolants, degreasers, fluxes, and metals.
Use enough forced ventilation or local exhaust (forced suction) at the arc to remove the
fumes from your breathing area.
Use a ventilating fan to remove fumes from the breathing zone and welding area.
If adequacy of ventilation or exhaust is uncertain, have your exposure measured and
compared to the Threshold Limit Values (TLV) in the Safety Data Sheet (SDS).
Welding can cause fire or explosion.
Do not weld near flammable material or where the atmosphere can contain flammable
dust, gas, or liquid vapors (such as gasoline). Move flammables at least 35 feet (11
meters) away or protect them with flame-proof covers (see NFPA 51B listed in Section.

?
Welding sparks can cause fires. Have a fire extinguisher nearby and have a trained fire
watcher ready to use it. After completion of work, inspect area to ensure it is free of
sparks, glowing embers, and flames.
Do not weld on containers that have held combustibles, or on closed containers such as
tanks, drums, or pipes unless they are properly prepared according to AWS F4.1 and AWS
A6.0 (see Safety Standards in Section 9).
Welding can cause fire or explosion.
Use welding helmet with correct shade of filter (see Section to choose the correct shade).
Wear welders cap and safety glasses with side shields. Use ear protection when welding
out of position or in confined spaces. Button shirt collar.
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.
Moving parts can injure.
Keep hands, hair, loose clothing, and tools away from moving parts such as fans, belts, wire drive rolls, and rotors. Keep all
doors, panels, and guards closed and secured.
