IMA 608D September 2004 OPERATING MANUAL RANGER 405D Part No. KA1453 Multi Process DC Welder & three phase 15 kVA Auxiliary Power Generator-Diesel Engine driven Engine-Kubota / Perkins SAFETY DEPENDS ON YOU Lincoln Electric welders are designed and built with safety in mind. However, your overall safety can be increased by proper installation and thoughtful operation on your part. Read and observe the general safety precautions on page 2 and follow specific installation and operating instructions included in this manual. Most importantly, think before you act and be careful. THE LINCOLN ELECTRIC COMPANY (AUSTRALIA) PTY. LTD. A.B.N. 36 000 040 308 SYDNEY. AUSTRALIA A Subsidiary of THE LINCOLN ELECTRIC CO. U.S.A. Associated Subsidiaries in Australasia, Asia, Canada, Europe, North and South America. THE WORLD’S LEADER IN WELDING AND CUTTING PRODUCTS PROTECT YOURSELF AND OTHERS FROM POSSIBLE SERIOUS INJURY OR DEATH. READ AND UNDERSTAND BOTH THE SPECIFIC INFORMATION GIVEN IN THE OPERATING MANUAL FOR THE WELDER AND/OR OTHER EQUIPMENT TO BE USED AS WELL AS THE FOLLOWING GENERAL ARC WELDING SAFETY PRECAUTIONS |
ELECTRIC SHOCK can kill | | --- | | 1. a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands.
b. In semi-automatic and automatic wire welding, the electrode, electrode reel, welding head and nozzle or semi-automatic welding gun are also electrically “hot”.
c. Insulate yourself from work and ground using dry insulation. When welding in damp locations, on metal framework such as floors, gratings or scaffolds, and when in positions such as sitting or Lying, make certain the insulation is large enough to cover your full area of physical contact with work and ground.
d. Always be sure the work cable makes a good electrical connection with the metal being welded. The connection should be as close as possible to the area being welded.
e. Ground the work or metal to be welded to a good electrical (earth) ground.
f. Maintain the electrode holder, work clamp, welding cable and welding machine in good, safe operating condition. Replace damaged insulation.
g. Never dip the electrode holder in water for cooling.
h. Never simultaneously touch electrically “hot” parts of electrode holders connected to two welders because voltage between the two can be the total of the open circuit voltage of both welders.
i. When working above floor level, protect yourself from a fall should you get a shock.
j. Also see items 4c and 6. | |
FUMES AND GASES can be dangerous | | 2. a. Welding may produce fumes and gases hazardous to health. Avoid breathing these fumes and gases. When welding, keep your head out of the fume. Use enough ventilation and/or exhaust at the arc to keep fumes and gases away from the breathing zone. When welding on galvanised, lead or cadmium plated steel and other metals which produce toxic fumes, even greater care must be taken.
b. Do not weld in locations near chlorinated hydrocarbon vapours coming from degreasing, cleaning or spraying operations. The heat and rays of the arc can react with solvent vapours to form phosgene, a highly toxic gas, and other irritating products.
c. Shielding gases used for arc welding can displace air and cause injury or death. Always use enough ventilation, especially in confined areas, to ensure breathing air is safe.
d. Read and understand the manufacturer’s instructions for this equipment and the consumables to be used, including the material safety data sheet (MSDS) and follow your employer’s safety practices.
e. Also see Item 7b. | 3. a. Use a shield with the proper filter and cover plates to protect your eyes from sparks and the rays of the arc when welding or observing open arc welding. Headshield and filter lens should conform to AS 1674.2-1990 standards. b. Use

FAQs

What are the key safety messages emphasized in the manual?

The manual stresses that safety depends on the operator, and operators should read both specific instructions in the operating manual and the general arc welding safety precautions before use.

How does the manual warn users to prevent electric shock?

It instructs not to touch electrically “hot” parts while the welder is on, to wear dry insulating gloves, to insulate from work and ground, and to maintain safe condition of the electrode holder and cables.

What precautions does the manual provide regarding fumes, gases, and ventilation?

It warns that welding fumes and gases can be hazardous, advises keeping the head out of the fume and using adequate ventilation/exhaust, and calls for extra care when welding materials that produce toxic fumes.
