Application And Mode Of Action; Preparations And Operation - Sinotec Sweldex Basic Wartungsanleitung

3. Application and mode of action

The design of the mobile SINOtec SWELDex basic is primarily intended for extracting and iltering welding fumes that arise when using different
methods of electrode welding, except for the extraction of welding fumes containing carcinogenic components (eg: stainless steel). For this
purpose only devices which are certiied according to DIN EN ISO 15012-1 may be used.
Basically, the device can be employed in all work processes where no carcinogenic particulates, in other words fumes and dusts, are released.
However, you should make sure that no sparks (eg: from any grinding process) are sucked into the ilter device.
The pollutants released during the work process, in the case of an attached exhaust arm, are taken in by the exhaust hood on the arm. They are
sucked in with the air low into the ilter device and here are directed through a pre-ilter and main ilter (two-stage iltration) with a separation
rate of more than 99.9% and cleaned. The cleaned air is sucked in by the fan and is returned to the work area.
In the case of the extraction of welding fumes containing carcinogenic components (eg: stainless steel),
in line with oficial regulations only devices which are certiied and approved according to DIN EN ISO 15012-1
are allowed to be operated in what is known as the recirculated air method.
The device described here does not fulil these requirements and therefore may not be used for extraction
of welding processes of this type!

4. Preparations and operation

• Take notice of the information on the type plate.
• Connect the ilter unit with the CEE plug to the power supply.
• Make sure that the extracted air can freely leave the blow out opening.
• To increase the stability of the unit, pivot the steering rollers outwards and set the brakes of the front ones.
The protective conductor of the welding smoke precipitator may not be supplied with strayed welding current
(error current), so please make sure to correctly connect the unit to the welding power source (UW VBG 15 § 43
para. 1). In order to guarantee a proper build up and disconnection of the welding circuit, the welding current may
only be switched on, if all connections of the welding circuit are build up and can only be switched off before all
connections in the welding circuit are disconnected. Make sure that the welding current return circuit between
work piece and welding unit is of low resistance and that connections between the work piece and the welding
smoke precipitator are avoided.
