Introduction to Welding Technical Parameters of LWG600A Diesel Welder Generator

July 21, 2025

Welding Current Range: The LWG600A diesel welder generator has an extremely wide current adjustment range, which can be flexibly adjusted between 30A and 500A. This feature enables it to adapt to various welding scenarios, from fine thin-plate welding where a smaller current is used to prevent plate burn-through, to thick metal component welding where a larger current is applied to ensure the depth and strength of the weld seam, all can be easily handled. When welding 1mm thick thin plates, the current can be set between 30A and 50A to ensure the accuracy and stability of the welding; when welding 20mm thick plates, increasing the current to 400A - 500A can achieve a good welding effect.

Rated Welding Current and Duty Cycle: Its rated welding current is 500A, and when the duty cycle reaches 60%, it can output a voltage of 40V; when the duty cycle is 100%, the rated welding current is 400A, corresponding to a voltage of 36V. This means that in long-term, high-load welding operations, such as large-scale steel structure projects, the equipment can operate stably and maintain an efficient welding state. For example, in bridge construction, the LWG600A can ensure the welding progress and quality with stable output during continuous hours of welding work.

No-Load Voltage: The no-load voltage of the equipment is 76V. The relatively high no-load voltage helps to quickly establish an arc during welding arc striking, ensuring the smoothness and reliability of arc striking. Even when the electrode is in poor contact with the workpiece, it can easily strike the arc, laying a solid foundation for the smooth progress of welding work.

Applicable Electrode Specifications: It can adapt to a wide range of electrode diameters from 1.5mm to 10.0mm, covering from extremely fine electrodes to thick electrodes. Whether using 1.5mm fine electrodes for precision welding or 10.0mm thick electrodes for welding large components, the equipment can provide appropriate current and voltage support to meet the usage requirements of different electrodes.

Integration of Welding Processes: The LWG600A integrates a variety of advanced welding processes, including manual metal arc welding (MMA), cellulose electrode welding, tungsten inert gas welding (TIG), and carbon arc gouging, etc. In pipeline welding, cellulose electrode welding can be used for backing first, then manual metal arc welding for filling and capping; for welding stainless steel materials, the TIG welding process can ensure the beauty and corrosion resistance of the weld seam; and the carbon arc gouging function can be used for cleaning weld defects, opening grooves, etc.

Convenience of Current and Voltage Adjustment: It is equipped with a welding current/voltage parameter preset function, allowing operators to conveniently preset the required parameters on the control panel according to the welding process requirements. At the same time, the current adjustment of the equipment has a rapid response, which can quickly adjust according to the actual situation during the welding process, ensuring the stability of the welding process and the consistency of welding quality.

Dual Torch Operation Function: It supports the selection of single/dual torch operation modes, and the dual torches do not interfere with each other during operation. At large engineering construction sites, two welders can perform operations using different welding processes at the same time, which greatly improves work efficiency and saves construction space. For example, in the block construction of large ships, welding work on different parts can be carried out by two welders at the same time, accelerating the construction progress.
