fault display & trouble shooting

Cooling water fault will lead to output leg burn to red or capacitor damage.

Capacitor damage can lead to tank fail to resonance. Remove the capacitor and check one by one.

Switching power supply is applied for perfect protection and hard to damage for the working power. Only if high voltage, the power may be destroyed. Once destroyed, there is no indicated LED on. Over current protection will also make the power stop. Find the over current reason and after trouble shooting, supply power then the welder works normally.

Usually, the problem is water pipe jam caused by bad water quality or debris. So, check periodically and change water pipe when necessary.

Welder works normally, speed is low

⑴ Coincide the moulding open corner (VEE) with demand: the open corner of the ordinary carbon steel is 3-5.

⑵ The outsider diameter circular section surface of the axial magnet should be 75% times the inside diameter circular section surface. Does the axial magnet have any crack? Does it locate in the most suitable place? The water cooling of the axial magnet should be increased appropriately.

⑶ Has the squeeze roller been adjusted in place?

⑷ Does the width of the band steel meet the needs? (narrow width can influence the speed) The empirical factor multiplied is differently adopted, when the company calculates the welding line quality and the welding speed, and can also save the material.

⑸ Steel strip moulding, the appearance before entering the squeeze roller
