YC-300BC2
* In addition to this product (welding power source), a torch and gas regulator are required for welding.Key functions
-
Reduces noise through an arc start without using high frequencies. Also reduces electrode wear
-
Improved arc start performance that is ideal for welding for plant construction, etc.
-
Versatile waveform control that can be selected according to the application
-
Case structure with improved transportability and storage efficiency enables stacking
-
3-phase / single-phase, 200 / 220 V, 50 / 60 Hz (common)
High frequencies are not used when starting the arc, thereby reducing the impact of noise on other electronic devices. Furthermore, this model is equipped with a noise filter as standard.
This model achieves a stable output with high-speed control 1.6 times faster than conventional inverter machines. It is also equipped with energy saving functions.
The body is 7 kg lighter than conventional models. This product has adopted a case structure, allowing it to be vertically stacked in two tiers for transportation or three tiers for storage, thereby enabling effective use of space.
Noise reduction through an arc start without using high frequencies
Since no high frequencies are used when starting the arc, high frequency noise that affects other electronic devices is suppressed. Since the electrode surface is not roughened, the service life of the electrode is extended and stable operation can be performed even during frequent arc starts.
Improved arc start performance ideal for tack welding
The adoption of arc starts without using high frequencies has improved the arc start performance. Instantaneous starts are possible even when performing repetitive operations, such as for tack welding or when using an extension cable, making it ideal for welding in plant construction.
Versatile waveform control that can be selected according to the application
Equipped with various welding waveforms for middle pulse control (effective for thin plate welding) and low pulse control (optimal for medium to thick plate welding) as well as initial current control and other control for uniform welding. Settings can be performed on the front panel.
Effective even for DC manual welding
This product achieves high-quality welding of mild steel, stainless steel, high-tensile steel, Cr-Mo steel, etc., and can increase the efficiency of additional welding of the second and subsequent layers after TIG welding.
Effective check and protection functions
This product is equipped with an error indicator, power switch with a no-fuse breaker, electric shock prevention function, and connection terminals for various jigs.
Compact and lightweight case structure
This product has achieved a 7 kg lighter body than conventional machines. A case structure has been adopted for the ease of transportation and storage. The units can be stacked vertically up to two tiers for transportation and up to three tiers for storage.
