Observe all instructions and information from ð the Safety section. WARNING Danger of burns Immediately after the laser machining (soldering/ welding/cutting), the machined surfaces of the workpieces are very hot.
Page 59: Switching On/Off
| Operation Switching on/off Ensure that the supply line of the supply voltage is connected. Switching on Humidity within the product cabinet If the product was subjected to an environment with high humidity while switched off, it may be neces- sary to reduce the humidity within the product cabi- net.
Page 60 | Operation Switching off NOTICE Risk of damage due to freezing If the laser is in a cold area or one at risk of freezing temperatures, freezing water can damage the laser and the water lines. ð If you do not intend to use the laser for a pro- longed period of time, follow the steps listed in the section on decommissioning and disposal.
Page 61: Switching On The Laser Power Supply
| Operation Switching on the laser power supply High leakage current High leakage current upon switching on the laser power supply can result in shutdown of the laser power supply. In a stable condition, the typical leak- age current at 400 VAC is approximately 60 mA. In this case, use a residual current circuit breaker with a delay during the start phase.
Page 62: Test Mode
| Operation TEST mode For the TEST mode, you require an external computer on which the LaserNet software is installed in order to control the laser. The commu- nication between the computer and laser takes place by means of an Ethernet interface (see supplied technical data).

Page 66: Analog Control
| Operation 7.4.4 Analog control With the Analog control function, you can define the preselected power via the analog interface. The function is also available in ROBOT mode (see interface description in the supplied technical data). To use the Analog control function, a direct voltage signal of 0…10 VDC must be present at the analog interface (see supplied technical data).
Page 67 Contact the responsible IPG service department if the laser spot at the outlet of the process optics is invisible or exhibits irregulari- ties such as dark spots.
Page 68 | Operation To enable laser radiation in ROBOT mode, a laser program (program Laser program nos. 1–50) must be specified. Laser programs can be created via the program editor LaserNet software and stored in the internal memory of the laser (see section LaserNet program editor [} 106]).

Page 118 | Maintenance Check the quartz-block end-face for impurities (e.g. dark points). If you find impurities on the quartz-block end-face, perform the following steps. Remove a cleaning swab from the package without touching the wadding of the stick. Moisten the cleaning swab with a drop of isopropanol. Shake off excess isopropanol from the cleaning swab.
Page 119 | Maintenance Look through the microscope and swipe over the quartz-block end-face on the fiber connector with a light pressure. Figure 72: Cleaning the quartz-block end-face After 20 seconds at most, replace the cleaning stick if the cleaning is to last longer. Clean the protective conduit with compressed air outside of the cleaning station and screw this back onto the fiber connector once the cleaning of the quartz-block end-face is completed.
Page 120 | Maintenance Plug the cleaned fiber connector promptly and carefully into the optics (see the following figure). Align the markers on the fiber connector (A) and optics holder (B) with each other (1) and care- fully slide the fiber connector up to the stop into the optics (2). Figure 73: Plugging fiber connectors (here: a HLC-8 fiber plug into an FCH-8 adapter) Turn the large pin on the bayonet mount from position 1 marked on the adapter to position 2 (step (3) in the figure below).

Page 123 | Maintenance 9.1.4 Checking the water outlet The product is equipped with a water drain with a water-soluble mem- brane in the cabinet bottom. In the case of a leakage inside the laser, the membrane dissolves and the water can flow out through the water drain.
Page 124 | Maintenance Figure 76: Removing the left cover Look through the membrane mount, and check whether the mem- brane is present and undamaged. The membrane is a replacement part and is delivered in an assembly to- gether with the membrane mount and the membrane holder.

Page 125 | Maintenance If the membrane is damaged or not present, the entire membrane as- sembly consisting of the membrane mount, the membrane holder and the membrane itself must be replaced. To do this, proceed as follows: Hold the drain nut in place while unscrewing the membrane mount counterclockwise (wrench size 40 mm).
