Operating Manual of SZ-1800 2. Performance Index Welding material: all metal material include copper, aluminum and other work pieces except some low melting and hard alloy material like Tin, Zinc. Welding position: 1. Partial abrasion for equipment mould welding process. - Page 4 Operating Manual of SZ-1800 1. Plug argon tube ( Note: press plastic material in the connection part when pull out argon tube) 2. Plug above control wire 3. Plug the socket to 220V 50HZ single phase socket; and the socket grounding wire should available touch to ground.

If the tungsten needle is not sharp, electrode and work pieces will not be fused well.
- Page 10 Operating Manual of SZ-1800 6: Nitriding work pieces welding Much nitrogen molecule will penatrate into the workpieces when do nitriding. Nitrogen will overflow fastly in welding under high temperature, which lead to many gas holes in weld pool, even some melted metal will splash to tungsten needle and influence welding.

- Page 16 Operating Manual of SZ-1800 It is null if the pulse time screen show”---“when using resistance welding mode. At this time, adjust relevant pulse current value is available (refer to above sheet). Adjust relevant pulse current value lower about 30% when use stainless steel wire.
- Page 17 Operating Manual of SZ-1800 10: Electrode / Welding Wire Option Welding wire should be chose the same or similar material as nature. Too large difference in structure could lead to sand holes, air holes or even can be welded well. If the welding hardness it too low, the welding part will be abraded or sloughed.
- Page 18 Operating Manual of SZ-1800 11: FAQ (Frequently Asked Question) Common Reason Solutions Phenomenon tungsten needle 0.3mm-1.0mm position of the electrode, Far distance from tungsten needle to and keep distance to the work pieces in work pieces, but short distance from about 0.2-0.7mm height.
