High Power 220V Gas Protection Spot Welding Machine 80A 800W Butt Welder. Welding current: 0.5-80A continuously adjustable (ignition pulse).Applications: All precious metals, precious metal alloys, such as gold, silver, platinum, palladium, stainless steel, titanium, Where the weak metal arc welding can be welded. Before using the welder, you should first check whether the use of voltage power supply. On welder output terminal connected to the respective corresponding screw polarity (output line connected to the output poles should tighten). When working with a black line output clip clinching the workpiece, close to the tungsten needle, the distance depending on the size and shape of the workpiece may be, from the general tungsten needle and the workpiece is between 0.5-1 mm, it will be a good post position welding, inching feet Tap switch between the workpiece and the tungsten needle to produce high-temperature electric arc welding good moment workpiece. The discharge end of the tungsten needle before and during use must be kept sharp to maintain a good discharge state. Welding according to the size of the workpiece, the size of the solder joints, process requirements, changing the size of the output pulse current to achieve the desired effect (the machine can weld 0.5-2.8MM).
Clockwise rotation of the potentiometer, the output pulse current increases, whereas the output pulse current is reduced. 1 x Tungsten tungsten needle.
