Year of construction: 1996, condition: good (used), PTW 150 Complete orbital tube welding machine with two complete and fully overhauled welding heads, (and 2 extra fully operational welding heads, respectively for up to 2" and 4") (see pictures) for sale. It includes "collets" (clamping sleeves) for most pipe dimensions from ½" to 4". This equipment is one of 5 orbital welding machines I have had, and it has mainly been used on 54x2mm, in addition to building 5-6 central gas systems with tubes of 12-18 and 28mm, and some 88.9mm. The equipment is complete, ready to weld with cables, gas hoses, red. valve etc. The equipment is delivered in original transport boxes, has complete set of manuals/part lists. Buyers can have the equipment delivered to their door, and up to 1 week of free training (including with many years of experience!) anywhere in Europe! New orbital equipment with the same spec, would cost typical some €40k + with just ONE weldhead. (One enclosed weldhead is typical €12-13000 without collets, typical €300 /dimension you will weld) At the two plants in Norway that operated with nuclear power (Kjeller and Halden), the same type of welding machine was the only one that was able to weld according to the requirements they set! (like 100% Helium, - 200 bar, - vaccum etc) The user interface is simpler on newer machines, but if you can calculate the circumference of a tube, you are well off. If you are wondering if orbital welding is something for you, it involves very little risk when you can get complete equipment, delivered on your door step, welding program for all pipe dimensions from ½" to 4" and one week of training for €10k, (and in addition 3 decades of experience) Pgedpfoycwk Rjx Ag Toi
