Product Features of Medium Frequency Spot Welding Machine

1.三相供電，電網(wǎng)均衡，對電網(wǎng)沖擊小/3-phase power supply,balanced power grid with less impact

功率因數(shù)高達(dá)0.7-0.9(工頻0.4),大大降低了無功損耗。

The power factor is as high as 0.7-0.9 (power frequency 0.4), which greatly reduces the reactive power loss.

2焊接控制精度顯著提高/Greatly improved welding control accuracy

逆變頻率達(dá)到400Hz以上，焊接電流控制能力、控制精度相對于交流焊機(jī)提高了20倍。 The inverter frequency reaches more than 400HZ, and the welding current control and control accuracy are 20 tmes haner than that of AC welding machine.

3焊接質(zhì)量大幅度飛躍/Great leap in welding quality

電流波形平直，熔核尺寸穩(wěn)定范圍大，飛濺少，焊點(diǎn)表面質(zhì)量好。 The current waveform is straight, the nugget size is stable with a wide range and fewer splashes, and the surface quality of the soider joint is good.

4節(jié)省基礎(chǔ)投資、節(jié)能/Saving for basis investment and energy

電網(wǎng)功率需求低，僅為交流流電阻焊機(jī)的2/3;焊接時間短，電極壽命長。 The power demand of power grid is low. which is only2/3 of that of AC current resistance welding machine: the welding time is reduced and the electrode life is extended.
