= Bending bent elbow = = = Big Bend is how the formation made out of it? I'll help you answer

1. IF Bend power vertical external characteristics, dc with positive polarity (wire then negative) 2. IF Bend is generally suitable for the following 6mm sheet welding, with weld appearance, a small amount of welding deformation characteristics 3. shielding gas is argon with a purity of 99.99%. When the welding current is 50 ~ 50A, the argon gas flow rate of 8 ~ 0L / min, when the current 50 to at 250A, the argon gas flow rate of 2 ~ 5L / min. The welding arc length, welding ordinary steel, with 2 ~ 4mm is better, but when welding stainless steel, with ~ 3mm better, long the protection is not effective. 5. IF Bend To prevent weld porosity of welded parts such as rust, oil, etc. Be sure to clean up. 6. tungsten from the gas nozzle protruding length to 4 ~ 5mm ,, preferably in fillet welding and other places with poor shelter is 2 ~ 3mm, slotted deep in places is 5 ~ 6mm, distance from the nozzle to work is generally not more than 5mm. 7. IF Bend docking base, in order to prevent the back of the bottom bead is oxidized back also need to implement gas. 8. windproof and ventilation. Windy place, be sure to take measures to block network, and in the indoor ventilation should take appropriate measures. 9. IF Bend is well protected argon weld pool, and easy welding operation, TIG welding workpiece center line and should generally be maintained 80 ~ 85 ° angle, the angle between the filler wire and the workpiece surface should be as small, usually about 0 °.
