Preparation For Welding; Welding Sequence - Leister TWINNY T7 Bedienungsanleitung

Setting the speed, temperature, and air volume before welding
• If the drive is switched off, then the welding parameters for temperature, air volume, and speed are set as
follows in the working display (29):
• Using the "Up" (22) and "Down" (23) arrow keys, you can set the cursor to the desired working display
(29).
• Rotate the "e-Drive" (27) to set the setpoint. The set value is applied immediately.
• A switch is made to the function display after 5 seconds or by pressing the "e-Drive" (27).
Setting the speed, temperature, and air volume during welding
• If the drive is switched on, then the welding parameters for temperature, air volume, and speed are set as
follows in the working display (29):
• During welding, the speed working display is blocked and the cursor is positioned in the drive speed field.
• Briefly pressing the "e-Drive" (27) enables the speed setting and you can adjust the setpoint speed by rotating
the "e-Drive" (27).
• The block becomes active again after 5 seconds or when you press the "e-Drive" (27).
• Using the "Up" (22) and "Down" (23) arrow keys, you can set the cursor to the heating or air working

7.3 Preparation for welding

• The maximum overlap width is 125 mm.
• The sealing sheets must be clean and dry between the overlaps and on the upper and lower side.

7.4 Welding sequence

• Before the automatic welder is used, test welds are to be carried out in accordance with
the welding instructions of the material manufacturer and with national standards or guide-
lines. The test welds must be checked.
• Caution: If the heating is switched on but the device is not welding or if the device is in Cool down
mode, the hot-air blower (19) must be in the park position. Otherwise, the device may become
damaged.
