VT-SS CAUTION ! Do not splash water on the product. Water splashed over the electric parts can cause electric shock and short circuits. Do not give excessive force to connecting cables. Do not bend, pull, or pinch any cable forcibly. If the cable is damaged, it will cause an electric shock, short circuit, or firing.
VT-SS (2) Precautions for Handling In this machine, the linear guide (linear bushing) is used vertically. Accordingly, grease or oil may drip, but this is not an accident. In particular, when a new machine is used, lots of grease of oil will drip. In this case, wipe it off properly during machine operation.

VT-SS (1) Pressure adjusting knob This knob is used to adjust the pressure at welding. Turn the pressure knob to set the required pressure. (2) Pressure scale This scale is used to read the pressure at welding. For the relation of pressure between "Pressure scale"...
VT-SS 4. Installation and Connection When fixing the pressure follow-up mechanism, (1) Installation perform drilling by referring to the drawing. Short shaft specification Fix this machine on a high-rigidity driving section for use. If the rigidity is ! CAUTION not enough, the welding quality may be lowered by flapping.

VT-SS 5. Operating Method (1) Introduction We recommend you to use this machine (VT-SS) in combination with our pressure follow-up mechanism driving unit as a set. To obtain the performance of the pressure follow-up mechanism driving unit fully, read the "Operation manual for the pressure follow-up mechanism driving unit"...
VT-SS (2) Operating Method (1) Setting the pressure Turn the pressure adjusting knob to set the pressure. For the relation between the scale and pressure, refer to the pressure diagram (page 13). (2) Installing the welding electrode Install the welding electrode on the electrode holder.
VT-SS (3) Electrode Projection Allowance, Stroke, and Pressure Allowance Electrode projection allowance Determine the electrode projection allowance out of the electrode holder by taking interference with the workpiece, operational convenience, etc. into consideration. <Example of general electrode projection allowance>...
VT-SS (4) Pressure Diagram 7N spring Spring constant 0.61N/mm 4N spring Spring constant 0.30N/mm Pressure scale *1 This is the pressure when Main Shaft is pushed up 2.5 mm. *2 The pressure diagram represents theoretical values. To measure actual pressure, use a pressure gauge or spring balance.
VT-SS (5) Maintenance Management (1) Lubrication It doesn’t need to replace. If the movement become bad, please oil the friction parts a little. Please use the oil which isn’t sticky for the friction parts. Too much lubrication will cause the bad ability.
VT-SS 6. Product Specifications (1) Specifications 1 N to 7 N (spring type) Pressure range Recommended operating thrust "Operating pressure x 2" as standard 2.5 0.5 mm Pressure allowance Electrode holder Standard type: □3.2 *Refer to the drawing of electrode.
