Push Pull Environmental Systems

Lincoln Electric, Automation Division

New systems for welding, grinding, gouging and cutting operations provide cleaner, more cost effective and energy conscious environmental solutions

Environmental Push-Pull Systems from Lincoln ElectricMany manufacturers have gone to great lengths in recent years to develop work environments that help attract and retain superior employees. Everything from ergonomics to lighting has been upgraded to increase the effectiveness and productivity of production workers. With the new focus on “green” manufacturing practices, employers have a new set of opportunities to reduce their environmental impact, and operate in a more energy conscious manner.

Changing expectations and government regulations are also prompting manufacturers to examine their operations and to meet requirements or guidelines and optimize them for the well-being of the worker. For welding operations, Lincoln Electric offers weld fume extraction solutions for a wide variety of applications and fabrication environments. If a welding fabrication facility or welding school’s current welding fume control systems do not produce the general indoor air quality required – administrators may want to evaluate a Push Pull environmental system.

An alternative concept in shop fume extraction systems, Push Pull systems may be the best recommendation for welding operations impacted by these conditions:

  • Manufacturing and fabrication applications where fume extraction at the source is difficult
  • Fabrication of especially large work pieces
  • Shops that utilize robotic and hard automation welding fixtures
  • Manufacturing where welding work cell locations change

A Push Pull system captures shop air and welding fume within a given perimeter, filters it, and then pushes the filtered air back into the working air in the same area. This method reduces energy costs, as the heated or cooled air from the shop is circulated back into the manufacturing location rather than exhausted outdoors. Unique to Lincoln Electric systems is the methodology of filtering only the immediate work area (below the push and pull ducts). The alternative is to filter the full floor to ceiling area, which can dramatically increase costs.

A Push Pull system is a general ventilation solution, which can be used to supplement targeted control of welding fume at the arc. Push Pull systems are intended for use when the goal is to improve general indoor air quality. To comply with upcoming OHSA and EPA regulations, many U.S. plants must conduct performance testing to evaluate worker exposures and plant emissions. A complete range of welding fume solutions, including equipment intended for use specifically at the source, are also offered by Lincoln Electric.

The operation of welding fume control equipment is affected by various factors including proper use and positioning of the equipment, maintenance of the equipment and the specific welding procedure and application involved. Worker exposure level should be checked upon installation and periodically thereafter to be certain it is within applicable OSHA PEL and ACGIH TLV limits.

Lincoln Electric is the world leader in the design, development and manufacture of arc welding products, robotic arc welding systems, plasma and oxyfuel cutting equipment and has a leading global position in the brazing and soldering alloys market. Headquartered in Cleveland, Ohio, Lincoln has 38 manufacturing locations, including operations and joint ventures in 18 countries and a worldwide network of distributors and sales offices covering more than 160 countries.
