ESAB Welding & Cutting Products introduces the LHF 405 Pipemaster rectifier

ESAB Group : 05 September, 2006  (New Product)
A sturdy and robust SCR-controlled rectifier specifically designed for heavy-duty MMA welding with coated electrodes, basic Tig welding and air-arc gouging. Designed to provide high reliability and outstanding welding performance over a wide current and voltage range, the rectifier is ideal for use in pipelines, shipbuilding and offshore applications, general fabrication, civil construction, repair and maintenance, power generation and process industry applications.
A sturdy and robust SCR-controlled rectifier specifically designed for heavy-duty MMA welding with coated electrodes, basic Tig welding and air-arc gouging. Designed to provide high reliability and outstanding welding performance over a wide current and voltage range, the rectifier is ideal for use in pipelines, shipbuilding and offshore applications, general fabrication, civil construction, repair and maintenance, power generation and process industry applications.

The welding properties of the LHF 405 were configured to meet the requirements of welding with E-6010 cellulosic electrodes. The unit provides a consistently stable arc, even when starting from the lowest currents. When the arc is shortened, the arc force makes weld penetration easier, especially when the electrode is pressed against the welded material. The unit's vertical static characteristics keep a constant current, regardless of cable length or arc voltage, while the dynamic characteristics ensure a stable arc and ideal control of the molten weld pool. A high power factor lowers energy consumption and installation costs and the unit switches off automatically if it becomes overheated.

The wide current range allows the operator to optimize settings for a wide variety of filler materials. The operator may also adjust parameters during operation. LHF units are also equipped with hot start, arc force and automatic anti-stick functions.

The LHF 405 provides 240 amps at 100% duty cycle, 310 amps at 60% duty cycle, and 400 amps at 35% duty cycle. The setting range is 10A/20V to 400A/36V. Main voltage is 230/460 Vac, 3-60 Hz. A number of options and accessories are available, including a remote control unit.

With more than 100 years of experience, ESAB Welding & Cutting Products is one of the world's largest and most skilled manufacturers of welding and cutting equipment and welding filler metals. Ensuring customer satisfaction, a wide range of ESAB products carry the 100% Satisfaction Guarantee. Recognized as the technological leader in the industry, ESAB is committed to providing customized solutions for their customers.
