The advantage

HIGHER EFFICIENCY

Better efficiency as compared to Vacuum tube Welder

The efficiency of a solid state welder is greater than 85%

EASY FAULT DIAGNOSIS

Because the HMI shows the Because the HMI shows the fault of HF welder , like the fault of 3#board ,over-temperature, fault of water pressure,the opening and closing of the cabinet’s door,the over-current , the fault of negative bridge mos and positive bridge mos. The fault can be found and solved soon, therefore, the downtime is reduced.

EASY TROUBLESHOOTING & MAINTENANCE

They are easier to maintain because of their drawer style design . Troubleshooting and maintenance are also greatly simplified. This results in lower down time and contributes to enhanced productivity.

THE COLD COMMISSIONING

The cold commissioning shall be fulfilled before shipment .So the perfect HF welder is assured.
