Please study these operation safety instructions and respect them when installing, operating, and servicing the machine. The welding arc and spatter The welding arc harms unprotected eyes. Also be careful with reflecting flashes from the arc. The welding arc and spatter burn unprotected skin. Wear safety gloves and protective clothing. Danger of fire or explosion Pay attention to fire safety regulations. Remove flammable or explosive materials from the welding location. Always reserve sufficient fire-fighting equipment at the welding location. Be prepared for hazards in special welding jobs – for example, the danger of fire or explosion in welding of container-type work pieces.
Welding fumes Make sure that there is sufficient ventilation during welding. Take special safety precautions when welding metals that contain lead, cadmium, zinc, mercury, or beryllium.
Fire can break out from sparks even several hours after the welding is done!
If improperly used, the device can present risks to people and physical property. • Use the device in line with its designated use only. • Do not convert or modify the device to enhance its performance without appropriate authorization.
• Using clean water, rinse work pieces that have been degreased with chlorinated solvents, to prevent the risk of phosgene gas forming. Do not place degreasing baths containing chlorine in the vicinity of the welding area. • Adhere to the general fire protection regulations, and remove flammable materials from the vicinity of the welding work area before starting work. • Keep suitable fire-extinguishing equipment in the work area, ready for use.
The device may only be used by qualified personnel. • The product has been developed and manufactured in accordance with state-ofthe-art technology and the recognized safety standards and regulations.

Kemppi Robot Gun Mount T4 is a solid bracket without collision sensibility. It is recommended that the robot itself is equipped with the collision sensing ability, when Kemppi Robot Gun Mount T4 is used. Gun orientation can be adjusted in 30 degree steps.
The delivery for a gas-cooled gun includes the following components: • Kemppi Robot Gun Mount T2 or T4 • Operating instructions • Cylinder-head screws, M4×55 (6 pcs.) • Certificate of conformity • Connection cable
The holding force of the inserted springs is directly applied to the release flange and fixes the switching axis, which is positioned by three pins, in the zero position. In the event of collision, the switching axis tips over, the release flange pushes the spring plate toward the base of the housing, and the trigger is actuated by the spring plate’s actuating mechanism. The applied switching voltage is interrupted. Figure 5: Functional diagram

17.2 Materials This product consists for the most part of plastics, steel, and non-ferrous metals. Steel and non-ferrous metals can be melted down, so iron materials are almost infinitely recyclable. The plastic materials used are marked in preparation for appropriate sorting of the materials for later recycling.
Proceed as follows: 1. Remove the parts to be disconnected:
Oils, greases, and cleaning agents must not contaminate the ground or enter the sewer system. These materials must be stored, transported, and disposed of in suitable containers. Please observe the relevant local regulations and the disposal instructions on the safety data sheets supplied by the manufacturer of the consumables. Also, contaminated cleaning tools (brushes, rags, etc.) must be disposed of in accordance with the information provided by the manufacturer of the consumables.

17.4 Packaging The shipping packaging has been reduced to a minimum. Packaging materials are always selected with attention to their possible recyclability.
Unmounting may only be carried out by specialist personnel. Please make sure that the shutdown procedures are strictly observed before the unmounting work begins. Ensure this also for the components integrated into the welding system.
The pull-in tool accessory serves for the correct mounting of cable assemblies. The O-rings at the rod of the pull-in tool indicate the mounting positions of cable assembly versions A7 MIG Gun 500-g and A7 MIG Gun 500-w. The pull-in tool must only be used for Robot Gun Mount T2. To get the correct type of the adapter flange for the robot's 6th axis, please notify Kemppi about the robot manufacturer and model.
