AUTOMATIC VARIABLE CONTROLLED WELDER

DAW – 300SS
Equipped with an advanced microcomputer-controlled stepless engine control unit, Denyo's DAW-300SS engine-driven welder has achieved a new level of performance.

Microcomputer-controlled stepless engine control realizes markedly lower fule consumption, about 40% less then conventional models, and less engine noise.

• The extremely lightweight, compact design has reduced total weight by about 24%.

• The advanced IGBT microcomputer control ensures the highest operating efficiency of any model in its class.

• All operations can be easily and automatically controlled over a full 30A-300A range.

• The e-AVC 300 operates on a single-phase AC power supply.

The "e" in the highly functional e-AVC 300 model stands for ecology, economy and ease.

Environmentally friendly thanks to low fuel consumption and low noise

• The built-in microcomputer controls engina revolution automatically and smoothly, making the unit more suitable for various load conditions. The engine slows down automatically under no-load conditions, and this translates into more efficient fuel consumption and lower noise.

• Fuel consumption has been reduced by 15~40%, compared with previous models.

• This unit runs more quietly than any other model designed by Denyo.

Pawer genarator features highest efficiancy in this class

Adopting a permanent magnet-type generator and advanced IGBT microcomputer control system, energy loss has been reduced by 20%, making the e-AVC 300 the most efficient generator in this class.

Lightweight and compact
When compared with our models, the volume and the total weight have been reduced by 14% and 24%, respectively, making this unit easier to transport.

The best arc-welding characteriftics
The e-AVC 300's microcomputer-aided welding control assures quiet, optimum operation that will accommodate any kind of welding rod.

Claaner exhauxt gas
• The engine is equipped with a crankcase emission control system to catch blow-by mist.

• It is also equipped with an aluminum radiator to eliminate lead contamination.

Easy operation
• All operations can be automatically controlled over a full 30~300A range by a welding current regulating unit, eliminating the need for manual switching between strong or weak positions.

• The built-in microcomputer automatically controls engine revolution in a stepless manner fn conformity with single-phase AC load and welding load.

Single-phase AC power (up to 3 kVA) and the welding power (0 to 200A) can be operated concurrently.

• The generator unit is equipped with an automatic fuel/air vent unit.

Completely maintenance-free
The welder has no bearings, making it maintenance free.

"One-side" access makes maintenance easy

• Daily maintenance can be carried out from a single panel conveniently located on the side of the unit. The radiator can be easily cleaned when the front cover is removed.
