1. Using vertical outside characteristics of dc power supply, when using n-dodecylamine polarity (anode) wire connect
2. 6mm plate under general suitable for welding, has the weld moulding beauty, the welding deformation characteristics of small amount
3. Protection for argon gas, purity of 99.99%. When the welding current is 50 ~ 150A, argon gas flow for 8 ~ 10L/min, when the current for 150 ~ 250A, argon gas flow for 12 ~ 15L/min.
4. Tungsten pole from gas nozzle prominent length, with 4 ~ 5mm for beautiful, welding, the Angle of bad place is covered in 2 ~ 3mm, slotting deep place is 5 ~ 6mm, nozzle to working distance usually less than 15mm.
5. In order to prevent the appearance, welding stomatal welding parts such as have rust, oil, etc must be clean.
6. Welding arc length, welding ordinary steel, with 2 ~ 4mm is preferred, and welding stainless steel, with 1 ~ 3mm for beautiful, too long is to protect the result is bad.
7. Docking render, in order to prevent the bottom on the back of weld bead oxidation, the reverse side also need to implement gas protection.
8. To make argon gas well protect welding pool, and facilitate the welding process operation, tungsten pole centerline and welding place workpiece generally should keep 80 ~ 85 ° Angle, filling, wire and the surface of workpiece Angle should as far as possible, generally 10 ° little about.
9. Windbreak and ventilation. Has the wind the place, please take block nets declarations of measures, but in indoor should be take proper ventilation measures.
