Dot touching contact gas pressure semi auto spot welding machine
1. Three phase power supply, grid balance, small impact on the grid
The power factor is as high as 0.7-0.9 (power frequency 0.4), which greatly reduces the reactive power loss;
2. Significantly improved welding control accuracy The inverter frequency reaches above 1000Hz, and the welding current control ability and control accuracy are 20 times higher than those of AC welding machines;
3. Great leap in welding quality The current waveform is straight, the size of the nugget is stable, the spatter is less, and the surface quality of the solder joint is good;
4. Save basic investment and save energy The grid power demand is low, only 2/3 of the AC resistance welding machine; the welding time is short and the electrode life is long;
5. Human-computer interface, easy to operate Multiple sets of welding specifications can be stored and called with one key, real-time display of welding current and time; monitoring and alarm functions of welding pressure, cold water flow, and welding current.
FEATURE
Advanced welding machine, adopt principle of MF inverter . Change the three phase AC power into DC power.
Welding current is DC , no inductance , higher heat input and output efficiency , more reliable and stable welding quality
Three phase load balance, power factor is close to 1
Intelligent digital controller, more precise and faster control of the welding current. The adjustment precision is 20 times higher than the AC machine
Reduce the production cost, save energy, reduce the requirement for cables and maintenance cost, improve the induction factor.
Store energy in a special inverter, more adaptation to the fluctuation of the power grid.
Smaller size and lower weight of welding transformer, one third of the AC machine .
Be able to weld aluminum and galvanized material product
Especially suitable for welding three-layer metal sheet or very thin product
