Product Description

Introduction

Product Overview

The medium frequency inverter DC spot welding machine converts power frequency (50Hz) AC power into medium frequency (1000Hz) DC output. Compared with power frequency, the time resolution is higher, the control accuracy is improved, and the output current is not affected by changes in the secondary output circuit. It has high thermal efficiency, high output power rate, and better welding quality. Compared to traditional power frequency welding machines, medium frequency inverter DC welding machines are more efficient and energy-saving, which is a revolutionary technological breakthrough in the field of resistance welding.
Characteristic

Balanced three-phase electrical input, low impact of DC output on user's power grid, energy-saving, stable current, consistent welding points, and high welding quality.

FAQs

How long does it usually take for delivery from placing an order to receiving the goods?

The delivery time may vary depending on the model, configuration, and order quantity of the equipment. Generally speaking, standard configuration spot welding machines and laser welding machines can be produced and shipped within 2 weeks after receiving the deposit and confirming the order. For customized configurations or equipment with special requirements, the delivery time may be correspondingly extended, and the specific delivery time will be clearly communicated with the customer during order confirmation. We promise to do our best to shorten the delivery time and ensure that customers can receive the required equipment on time.
Which transportation method is usually used to transport spot welding machines and laser welding machines?

PDKJ usually uses sea freight to transport spot welding machines and laser welding machines, as it is suitable for large-scale and long-distance transportation. Meanwhile, sea transportation can also ensure the stability and safety of equipment during transportation. Of course, if the customer has particularly urgent requirements for delivery time, we can also develop an air freight plan based on their needs, but the corresponding shipping cost will be negotiated and determined.
How is the packaging of ordinary spot welding machines and laser welding machines carried out?

The packaging of ordinary spot welding machines and laser welding machines adopts professional wooden box packaging method. We will customize suitable wooden boxes based on the size, weight, and shape of the equipment, and reinforce them with high-strength wooden boards and strips to ensure their stability during transportation. Inside the wooden box, we will use shockproof materials such as foam plastic, bubble film, etc. to wrap the equipment to prevent the equipment from being damaged due to collision or vibration during transportation. In addition, we will also label clear transportation signs and warning information on the outside of the wooden crate to ensure safety during transportation.
