Resistance Welding
Resistance welding is a method in which the welding works are heated by resistance heat generated by sandwiching the welding workpieces with welding electrodes, passing current through them, and the metal is welded while pressurizing the works.A resistance welding machine composed of welding power supply, a weld head and an electrode. The welding power supply controls a welding current,the weld head exerts a pressure on the material to weld and the electrode provides welding current and pressurization force to the part under welding. We have been providing various kinds of welding power supplies and welding heads to meet these requirements.

Contact Resistance Tester
Weshine Electric Manufacturing Co., Ltd
The loop resistance tester is used to test the conductive loop resistance of various switchgear, and the test current shall not be less than 100A. Due to the oxidation of the contact surface, poor contact tightening and other reasons, the contact resistance increases. When a large current flows, the temperature of the contact point increases, which further accelerates the oxidation of the contact surface and further increases the contact resistance.

Ground Earth Resistance Tester
2678X
Shenzhen Chuangxin Instruments Co., Ltd.
Ground Earth Resistance Tester verifies the integrity (continuity) of the protective bonding of the equipment (Class I equipment) designed to secure safety through the basic insulation and protective earthing. It is also called earth (ground) bonding test. If the continuity of the protective bonding is confirmed, we can conclude that the equipment has the requirements for preventing electric shock even if the insulation between the primary circuit and the accessible conductive section fails and a fault current flows through the distribution system.

Surface Resistance Tester
MR – 1
The different specific resistances are specified by selecting one of the pre-programmed materials, or by measuring the specific resistance of unknown materials and entering the result. Preferably the coat thickness is displayed, but the measurement and display of the actual resistance, the square resistance and the specific resistance is possible, too. All measured values can be transmitted into a PC via a serial interface. Controlling the MR-1 on the other hand is not possible.

SparkFun Decade Resistance Box
This is the SparkFun Decade Resistance Box, an involved PTH soldering kit that allows you to quickly and accurately dial in a specific resistance value between 0 and 999,990 Ω, in 10 Ω increments. The concept is simple, a decade box is a tool that contains resistors of many values that can be accessed via mechanical switches. All you need to do is just adjust the knobs to output any of the discrete resistances offered by the box. Once assembled, each kit will have controls that correspond to the digits in a decimal number - a control for the tens position, a control for the hundreds position, and so on.
