Current monitor LWM-100A
LWM-100A is a high accuracy and multi function monitor for the measurement of current, electrode voltage and power time of resistance welding.
- input voltage (1 AC in diameter 100 ~ 240V), respond to any occasion.
- wide measuring range (0 ~ 199.9KA, 0 ~ 9.99V)
At the same time can display dynamic curve, welding current and voltage between the electrodes of the average effective value and peak value
- monitoring time unit can according to the determination of MS and CYC type automatic switch
Input and output signals of I/O - rich, corresponding to the resistance welding quality management.
There are two kinds of internal and external - Determination method. Can be used to determine the different parameters of the automaton.
- can measure multiple resistance welding machine. Single phase AC, AC / DC inverter, capacitor energy storage, transistor type, three-phase secondary rectification, pulse type.
Pressure monitor LWM-200A
LWM-200A is a multi - functional and high - precision pressure monitoring instrument for the measurement of the pressure of resistance welding.
- input voltage (1 AC in diameter 100 ~ 240V), respond to any occasion.
In the dynamic display of the pressure fluctuation process curve. And show the maximum, minimum and average values as well as the state decision results.
- displays a list of 5 recent management pressure monitoring
"Any pressure point zero function; at any time under the pressure gauge decision function
According to the actual demand, with a variety of pressure sensor, the pressure measuring range (0.5 ~ 900Kg).

In a variety of alarm function; Determination of standard by external selection (15 group). With convenient and automaton.
