The automatic tank welder machine is specifically designed for the efficient horizontal welding of huge diameter storage tanks, ship's hull, etc., ranging from 6m diameter and above. The recommended plate thickness is from a minimum of 6mm to a maximum of 50mm while recommended plate height is from a minimum of 1200mm to a maximum of 3000mm.

The tank top is transported by a DC gear motor. Both the JTW 11.3 (single side welding model) and JTW 11.2 (Double sided welding model) weld both internal and external walls simultaneously via the submerged arc process. The flux support unit consists of two knurled drive wheel, belt system and a recycling capacity of up to 95%.

The unit also incorporates a travel speed indicator with an override fast jog button that allows the tank to be repositioned. Travel can be manually initiated on arc start. For added safety, both welding stations are fitted with emergency stop facilities designed to de-activate all control and welding functions at the touch of a button. Seam tracking on the tank wall is accomplished through motorized vertical slides.

The Lincoln NA3S automatic welding heads are recommended for reliable results. Other features of the automatic tank welder include:

• Heavy motorized carriage supporting both welding stations
• Telescopic legs for welding adjustment from 300 -1200mm
• Welding head for vertical welding adjustments of up to 300mm
• Frame head spreader designed for easy tank top loading and clamp facilities
• Safety cages, ladders handrails are featured with floors and roofs of non slip plate

The automatic tank welder (for all models ) consists of:

• An operator seat
• An weather-proof curtains
• An pre-heat torches & brackets
• An cross seam head adjusters
