FABRIGAS is and has been a “first responder” as the country has grown and the need for new products to meet the needs of a growing nation and the new categories of business spawned by this growth.

Today, FABRIGAS is the unquestioned leader in Fire Suppression Plans and Fire Equipment. The use of Nitrogen, internationally, to fill tires in-stead of compressed air, for safety and economic reasons, has grown from commercial use in airplane tires, buses, commercial trucks and now, private vehicles has led FABRIGAS to introduce “Nitro-Tire” to the Belizean company and individual. FABRIGAS is also a large supplier of

commercial Welding Equipment and supplies that has enabled Belizean businesses to enjoy the benefit of using superior products and equipment. Other categories like Abrasives and Grinding plus the professional testing of Scuba Tanks and large gas cylinders has contributed greatly to the safety of the country’s many users.

UTP- More than four decades of experience in developing and production of welding consumables.

The production program specializing in technical application contains spe-cial electrodes in the corresponding special- and standard alloys. Based on

developing technologies in the production of high quality welding consumables and on the latest production equipment, the UTP program of welding consumable is continuously extended.

UTP products are finding applications in all industries. The success of UTP is depending on one side on a streamlined program and on the other side on well organized technical service available for all customers around the world.

Miller’s long history of innovation includes the first welder with a built-in wire feeder, the Millermatic® 35. Not until 1971 was there an “all-in-one” MIG welder that was affordable and easy to use—and perfect for welding on au-tomobiles, farm and ranch equipment and home-hobby projects. Millions of Millermatics later, this product family has rekindled the love of metalworking just for fun (witness the popularity of shows like American Chopper), and it has turned many garage-shops into multi-million dollar fabrication businesses.

On the industrial side, Miller led the charge that made “inverter” technology widely accepted with the XMT® 304 multiprocess welder. Today, advanced products like the XMT, Axcess®, Dimension™ NT 456 and Millermatic 350P set the industry standards for reliability, arc quality, productivity and ease-of-use. In fact, Miller believes that putting more technology inside the machine should make it easier to use, not harder. That’s why its advanced welders are also among its most operator-friendly.

UTP 82 ASChamfering electrode for metallic materials

Application FieldThe strongly coated chamfering electrode UTP 82 AS can be used on all steel grades with ferritic and austenitic structure, as well as cast iron, cast steel and all non-ferrous metals. It enables workpieces to be grooved out in a very simple way. UTP 82 AS is also suitable for removing corroded metal layers and for fusion-cutting metallic materials.

Welding properties UTP 82 AS strikes easily and generates a high gas pressure, enabling a clean and smooth cut to be achieved.

Welding InstructionWhen grooving it is advisable to tilt the plate in the direction of working, so that the molten parent metal can run off better. The electrode should be inclined to the parent metal as horizontally as possible (approx 15°) and kept constantly in contact with it. The working speed is increased by slight pushing movements in the direction of working. Parent metal left on the edge of the groove is easily removed with the slag hammer. Machining the groove down to the bare metal may be advisable, depending on the circumstances.
