Frequently Asked Questions
Can this Dual Head Spot Welding Machines be custom-made?
+
-
Absolutely. We specialize in non-standard customization. We can provide tailored solutions based on your workpiece dimensions, welding process requirements, and production line tempo.
How significant is the energy saving compared to traditional AC welders?
+
-
It's remarkably significant. The medium frequency inverter technology achieves a power factor of over 0.95, saving 30%-40% more energy than traditional AC welders (which have a power factor of about 0.6-0.7). This leads to substantial savings on electricity costs over time.
How do you ensure the weld spots don't crack when welding automotive high-strength steel?
+
-
Through precise control. Our intelligent controller provides accurate adaptive control over welding current, time, and pressure, ensuring optimal heat input. This prevents issues like burn-through or cold welds, guaranteeing weld spot strength.
What after-sales services do you provide?
+
-
We offer comprehensive support. This includes free installation and debugging, on-site operator training, a 1-year warranty, lifetime technical consultation, and a rapid spare parts response.
Can it be integrated into our existing automated production line?
+
-
Absolutely yes. The machine is designed with compatibility in mind, featuring standard communication interfaces (e.g., PLC, I/O). Our engineers will assist you in achieving seamless integration.
