When welding or cutting what five things are to be aware of? - ✔️✔️-Flames-Sparks-
Fire Hazards-Harmful Rays-Fumes
What effect can intense visible light rays cause? - ✔️✔️Eye strains, or temporary
blindness
Effects of excessive noise? - ✔️✔️irritability, headaches, rise in blood pressure, loss of
concentration, hearing problems, ect
What is the order of lightest filler plate to darkest (welding mask) - ✔️✔️9.10, 11, 12 ,14
types of GMAW electrodes - ✔️✔️solid and cored
what do GMAW electrodes do ? - ✔️✔️carry electricity to the weld puddle and are filler
metal
how are wire electrodes sold? - ✔️✔️1 lb, 11 lb, 33 lb all the wat to 55 gallon drum size
GMAW wires come as copper coated electrodes because? - ✔️✔️better conductivity,
resistance to rust, and better arc starts.

molybdenum, nickel, silicon
GMAW wire code ER70S-X what does the 70 mean ? - ✔️✔️this is the tensile strength
of the wire in psi =70,000
GMAW wire code ER70S-X what does the S mean ? - ✔️✔️solid
GMAW wire code ER70C-Y what does the E mean ? - ✔️✔️E=electrode and in the
case of GMAW it is also the filler wire
