5.Remove all combustible materials from the work site. If you can not remove them, protect them with fire- proof covers.
NEVER perform welding operations on a container that has held toxic, com- bustible or flammable liquids or vapors. NEVER perform welding operations in an area con- taining combustible vapors, flammable liquids or explosive dust.
VENTILATION
Ventilate welding work areas adequately. Maintain sufficient air flow to prevent accumulation of explosive or toxic concentrations of gases. Welding operations using cer- tain combinations of metals, coatings and gases generate toxic fumes. Use respiratory protection equipment in these circumstances. BEFORE welding, read and understand the Material Safety Data Sheet for the welding alloy.
ELECTROMAGNETIC COMPATIBILITY
BEFORE installing a MIG power source, inspect the surrounding area checking the following points:
1.Make sure there are no other power supply cables, control lines, telephone cables or other devices close to the power source.
2.Make sure that telephones, televisions, computers or other control systems are not in the working area.
3.People with
Reduce interference by following these suggestions:
1.If there is interference in the power source line, mount an E.M.T. filter between the power supply and the power source.
2.Shorten the output cables of the power source, keep them together and connected to ground.
3.Securely fasten the panels of the power source in place after performing maintenance.
PROTECTIVE WELDING GASSES
1.These welders use only inert or
2.DO NOT use gas from unidentified cylinders.
3.DO NOT connect the cylinder directly to the welder. ALWAYS use a pressure regulator.
4.Make sure the pressure regulator functions properly. Read the instructions supplied with the regulator.
5.DO NOT lubricate the regulator with oil or grease.
6.Each regulator is designed for use with a specific gas. Make sure the regulator is designed for the protective gas being used.
7.DO NOT use damaged cylinders.
8.Make sure that the cylinder is safely secured tightly to the welder with the chain provided.
9.DO NOT carry the cylinder by holding it by the valve.
10.NEVER expose cylinders to excessive heat, sparks, slag or flame.
11.Make sure that the gas hose is ALWAYS in good condition.
12.Keep the gas hose away from the working area.
