The MultiWave 215DC YT-81420 TIG inverter welder is a safe and reliable device for HF TIG welding, using a non-consumable electrode in a gas shield with high-frequency arc ignition technology. It meets all CE requirements for welding equipment and has test-approved high-voltage shock protection. It is equipped with an LC filter that protects other devices connected to the same network from voltage spikes generated during welding. All technical parameters are accurate, and the welding process itself is stable and pleasant.
TIG is one of the more difficult welding methods to master, yet it allows experienced welders to achieve welds with the best mechanical properties and high aesthetics. The MultiWave 215DC is a full-fledged TIG (HF arc ignition method) with basic functions, designed for those in the automotive and decorative industries. A maximum current of up to 210 A allows for the seamless joining of sheets up to 5-6 mm thick.
The MultiWave 215DC was developed through a collaboration between YATO and RILAND. Riland, the brand owner, is a company listed on the Shanghai Stock Exchange specializing in welding equipment. As a leader in the Chinese market, it devotes significant resources to research and development. One of the results of this work is a dedicated microprocessor for welding equipment that autonomously manages the entire welding process. A proprietary method of sampling the welding current and managing the current transformation process translates into unprecedented ease of placing a correct weld at this price point.
The RICHIP microprocessor is capable of analyzing welding process parameters at up to 200 million times per second and enables control of the latest generation IGBT transistors at up to 70,000 times per second. This allows, among other things, for the welding process to be performed efficiently. The welding current and voltage are adjusted to the current welding conditions at a speed of up to seventy thousand times per second, and each decision regarding the degree of transistor opening/closing is made based on over 2,800 samples!
RICHIP is an all-in-one solution. There's no need for additional electronics to implement dedicated welding functions, such as ARC FORCE or HOT START. The lack of additional circuits reduces the device's failure rate and ensures that the impact of interference generated during the current transformation process on welding quality is marginal and completely eliminated by the number of samples.

Function Description:
Post-glow - sets the shielding gas supply time after welding.
Hot start - When the electrode is placed on the workpiece, the welder increases the welding current for a fraction of a second, significantly facilitating arc ignition.
Arc force - regulates the arc dynamics depending on the distance of the electrode from the workpiece. RICHIP monitors welding parameters approximately 200 million times per second and analyzes the measurement results in real time. Then, by controlling transistors at a speed of up to 70,000 times per second, it increases or decreases the welding current. This results in the best possible welding power source quality for a given current setting.
Anti-stick - cuts off the welding current when the electrode shorts, allowing the electrode to be detached from the workpiece.
VRD - this function reduces the open-circuit voltage from approximately 60 V to a level safe for humans. Despite its significant safety impact, this function is often disabled by users. This is due to arc ignition problems, especially among those with little experience. Most inverter welders monitor the output current using analog sensors, which, in short, slows the response time and consequently makes arc ignition more difficult. The RICHIP handles this differently. It generates a waveform with a frequency of approximately 200 MHz in the welding current circuit. It monitors waveform distortions in real time, which vary depending on the welding stage. The moment the electrode touches the workpiece is detected in a fraction of a second, disabling the VRD function and simultaneously activating the HOT START function. Arc ignition is prevented.
Overload and overheating protection (fan on demand) - RICHIP monitors the temperature of critical components in real time. Depending on the temperature, it first controls the fan speed, but when the temperature reaches a certain level, the fan speed is reduced.
If the level is too high, the microprocessor smoothly reduces the output current, allowing for electrode burnout or a controlled termination of the weld. In most welders on the market, the moment of overheating immediately shuts off the welding current, often resulting in the need to make mechanical adjustments to the welded components. This problem does not occur in devices with RICHIP.
