Operating instructions for OSK series S / G Tacking with the OSK: It is also possible to tack with the orbital welding head. Insert the prepared pipes in the welding head, so that the joint with the electrode forms a line. Close the welding head and start the tacking process.
Operating instructions for OSK series S / G 7.7. Welding process Rotor back in basic position Completely open the clamping shell housing Insert the tacked pipe and align central to the electrode. Close clamping shell housing and weld together. It is mandatory to form depending on the application.
Do not make any modifications to the tool. Do not expose the product to extreme environmental conditions (f. ex. rain). Use only accessories of Orbitec GmbH. Regularly check and, if necessary, replace the electrode. Blow out the water channels of the water-cooled clamping shell housing with compressed air prior to putting these down, in order to avoid leaks.
Operating instructions for OSK series S / G 8.2. Cleaning The welding head must be cleaned regularly, to reduce the wear and tear and to increase the service life. If necessary, this guideline must be adjusted according to use and degree of contamination.

Operating instructions for OSK series S / G d. Clean the individual disassembled parts to remove welding beads, soot and other contamination. Clean the contact areas of power transmission and rotor with fleece (Item. no. 1.1.4125) Clean contact areas with fleece Clean and degrease all individual parts as well as the body with isopropyl or benzine and then blow out with compressed air.
Operating instructions for OSK series S / G 8.3. Setting the end switch cam The end switch cam is already set at the factory. In the event that it needs to be readjusted, proceed as follows: The adjustment is carried out in fully assembled condition, the following illustration shows schematically the function of the end switch.

Drive shaft Fixing Coupling Do not dismantle the drive shaft. Use only original Orbitec drive shafts. Tighten the threaded pins of the coupling only on the intended flattened areas of the drive shaft. Tension on flattened areas (Remaining components hidden)
Operating instructions for OSK series S / G 8.5. Exchange of graphite nodule The graphite nodules ensure that the rotor can turn freely a they centre it in the middle. The balls in the graphite nodules press the rotor to the current loop and thereby ensure the power transmission.
Page 30
Operating instructions for OSK series S / G Correctly insert the new graphite nodules only slightly tighten the screws. Lay the rotor so that the graphite nodules are lying in the guide slot. Carry out circular movements with the rotor to align the graphite nodules Tighten the graphite nodules, while the screw only projects as far as necessary from the rotor.
Operating instructions for OSK series S / G 8.6. Setting of tension lock OSK 21 CW and OSC 38 CV are fitted with space saving tension locks. In case of under- or oversized pipe, if necessary ,readjustments can be made with the adjusting screw to ensure a safe tightening.
