Welder welder cartridge filter is to provide a welding power supply of electrical properties, due to the flexible and easy to weld solid and reliable, even after welding the base material of equivalent strength and advantages of widely used in various industrial fields. Welder source in Zhengzhou cartridge filter is designed according to welding characteristics developed efficient mobile dust removal equipment. Welder cartridge filter configured two suction arm, the bottom with two directional, two universal polyurethane wheels with brakes for mobile dusting station. Suction arm can be rotated 360 °, the suction cover by pulling the handle, with the flexibility to easily operator wishes to reach the target position and angle inhale smoke and air positioned themselves in the absence of external force. Depending on needs, optional 2m, 3m or 4m flexible suction arm. Using true temperature suction hose, fire-retardant, wear-resistant composite material will not crack due to burn after Mars, longer life; arm tube diameter 160mm. Clean air filtered through air vents beneath the cleaner directly cycle directly into the interior. Filter the internal use of full-rotor automatic cleaning dust, so the filter surface cleaning more thoroughly, to ensure the welding cartridge filter can always have a constant amount of suction.
