IF Bend, Hebei billion gold pipe, large diameter IF Bend provided by Hebei billion gold piping. IF Bend, Hebei billion gold pipe, large diameter Hebei billion in gold IF Bend Pipe Manufacturing Co., Ltd. (www.yijinguanjian.com) 2013 upgrade been newly launched IF Bend Features: 1 vertical external characteristics of power supplies, DC When using positive polarity (wire then negative) 2. generally less suitable for 6mm plate welding, weld appearance with a large diameter intermediate pipe, a small amount of welding deformation characteristics 3. protective gas argon IF Bend, purity 99.99%. When the welding current is 50 ~ 50A, the flow rate of the argon gas pipe 8 ~ 0L/min IF manufacturer, when the current of 50 to 250A thick intermediate pipe when the argon gas flow rate of 2 ~ 5L/min. 4 from the gas tungsten nozzle protruding length to 4 ~ 5mm, preferably, welding, etc. at the corner where it is poor shielding 2 ~ 3mm, where it is deeply grooved 5 ~ 6mm, the distance from the nozzle to the working generally not more than 5mm. 5 To prevent weld porosity of welded parts, if any, rust, oil, etc. Be sure to clean up. IF Bend Features 6. Welding arc length, welding ordinary steel to 2 ~ 4mm better, but when welding stainless steel to ~ 3mm better, long the protective effect is not good. 7 when the docking base, the bottom of the back to prevent oxidation of the weld, the need to implement the backside gas. 8 is well protected argon weld pool, and ease of welding operation, the center line of tungsten welding of the workpiece should be maintained 80 ~ 85 ° angle, the angle between the filler wire and the workpiece surface should be as small as possible, is generally about 0 °. 9 windproof and ventilation. Windy place, it should take steps to block network, and in the indoor ventilation should take appropriate measures.
