MK 3A/4/5Group Number: 2231
The GCE BUTBRO MK3A/4/5 is a high pressure, sturdily constructed and well balanced welding and cutting torch replacing the GCE BUTBRO MK 2, together with additional improved progressive features. Each component (shank, mixer, cutting attachment) is inter-changeable with other leading makes of type 3/4/5 equipment.
It has front mounted colour coded control valves, employing stainless valve spindles fitted with both ‘O’ ring and nylon seals; providing fine adjustment and leak-free conditions.
The shank is common to both welding and cutting heads, the same quick positive positioning and leak-free means of attachment being used for both. GCE BUTBRO torches and nozzles conform to BS EN ISO 5172.
WELDING AND HEATING
Designed for welding work from 18 swg to over 1“ thickness using type 3/4/5 swaged nozzles sizes 1 - 90 litres. The mixer seats on serrated toothed faces allowing the operator a selection of positive nozzle positioning through 360°. Also can be used for heating, with either acetylene or propane heating nozzles, together with a heating neck.
The cutting head is nozzle mixing, enabling the operator to use either acetylene or propane fuel gases by fitting the appropriate nozzle. A range of ANM and PNM nozzles are available for clean efficient cutting of material thickness from sheet metal to 50 mm (2“) using both acetylene, and propane fuel. It’s versatility allows gouging, flame cleaning etc., to be supplied to customer’s requirements.
PROPANE SUPER HEATING
Using a propane super heating mixer and 10“ or 28“ stainless steel super heating neck an intense heat output of up to 600,000 Btu/H is obtained. Ideal for heating castings and similar large articles.
