Intermediate Frequency Inverter DC Spot (Convex) Welder
DTB-80 DTB-160 DTB-240 DTB-280 DTB-340 DTB-450
Energy saving, power saving, high efficiency, low operating cost, and high welding quality.
Product overview: The medium frequency inverter DC spot welding machine converts the power frequency (50Hz) AC to the medium frequency (1000Hz) DC output. The time resolution is higher than that of the power frequency, the control accuracy is also improved, and the output current is not affected by the change of the secondary output circuit. It has high thermal efficiency, large output power rate and better welding quality. Compared with the traditional power frequency welding machine, inverter medium frequency DC welding will be efficient and energy-saving. It is a technological revolution breakthrough in the field of resistance welding.

1,How are the electrodes of the spot welding machine maintained and replaced during the welding process?
Answer: The electrodes of the spot welding machine gradually wear during use, so they need to be checked and maintained regularly. When electrode wear is severe, new electrodes should be replaced promptly. When replacing electrodes, choose suitable electrode materials and specifications and follow the correct installation and adjustment procedures outlined in the equipment manual. Additionally, regular cleaning and polishing of electrodes can extend their service life.
2,Does the spot welding machine have energy-saving features?
Answer: Yes, our spot welding machine has energy-saving features. The equipment automatically enters a low-power mode when idle or not in use, reducing energy consumption. Additionally, we utilize an efficient power management system to ensure optimal energy utilization during the welding process.
3,How to control noise generated during the welding process of the spot welding machine?
Answer: Noise generated during the welding process of the spot welding machine mainly comes from the contact between the electrode and the workpiece and the vibration generated when the current passes through. To control noise, the following measures can be taken: Firstly, choose welding equipment and power supply systems with low noise to reduce noise generation sources. Secondly, arrange the work area reasonably, placing the welding equipment in a place with good sound insulation to reduce noise transmission. Additionally, operators can wear noise-canceling earplugs or earmuffs to protect hearing health.
4,How is the accuracy and stability of the spot welding machine ensured?
Answer: Our spot welding machine adopts advanced control systems and precise mechanical transmission mechanisms to ensure welding process accuracy and stability. During the manufacturing process, we strictly adhere to quality control standards and conduct rigorous quality inspections to ensure the equipment's stability and reliability.
5,What should be paid attention to when the spot welding machine welds thin sheet materials?
Answer: When welding thin sheet materials, the spot welding machine needs to pay special attention to controlling the welding pressure and welding time to avoid over-welding, which may cause material deformation or burn-through. It is recommended to use smaller welding currents and shorter welding times, and adjust the welding pressure appropriately to achieve good welding results.
6,Does the spot welding machine support counting function?
Answer: Yes, our advanced models of spot welding machines support real-time counting function, allowing users to better calculate the length of work and whether workpieces are missed welds.
7,What should I do if my machine is damaged during the warranty period?
Answer: First, our engineers will assist you in diagnosing the issue through online guidance. If any parts are damaged during the warranty period, we will ship the parts to you for replacement free of charge. If you are unable to resolve the issue by replacing new parts, we will dispatch engineers to your factory to assist in repairing the machine.
For foreign users, we prioritize solving problems for you through remote phone and video calls. Over the past decade, almost all issues have been successfully resolved through remote phone and video calls. If part replacement is necessary, it will be done through express delivery, with remote guidance for installation.
If the problem still cannot be resolved, we will negotiate and dispatch after-sales engineers to your location for repairs.
8,How is the welding speed of the spot welding machine adjusted?
Answer: The welding speed of the spot welding machine can be adjusted by adjusting welding parameters and control systems. By increasing or decreasing parameters such as welding current, welding time, and welding pressure, you can control the welding speed to adapt to different welding requirements.
