1.2.5 Electric shock

All electric shocks are potentially fatal and therefore live wires and/or parts should never be touched.

Insulation must be kept from the piece to be welded and from the ground by wearing insulation gloves and clothing.

Garments such as gloves, shoes, hats, clothings and body must be kept dry at all times and it is to be avoided working in humid or wet areas.

Never touch or hold the piece to be welded by hand; if the slightest electric shock is felt, welding should be stopped immediately; the unit is not to be used until the problem is identified and solved by qualified personnel.

Frequently inspect the primary power cable for damage or cracking of the cover and replace immediately damaged cable. Disconnect power supply cable from mains before replacing cables or before removing unit covers.

Always replace any damaged parts of the unit, with original material.

Never short out or in any other way defeat the safety interlock devices and make sure that the power supply line is equipped with an efficient earth plug.

Make sure that the work table is connected to a good earth ground.

Any maintenance is to be carried out by qualified personnel only that is to be aware of the risks due to dangerous voltages necessary for the operation of the unit.

1.2.6 Pacemaker

Person wearing electronic life support devices (such as pacemaker) should consult with their doctor before going near arc welding, cutting, gouging or spot welding operations in order to make sure that magnetic fields associated with high currents do not affected their devices.

SECTION 2 --- GENERAL DESCRIPTIONS AND PRODUCT SPECIFICATIONS

2.1 INTRODUCTION

The welding power supplies deliver constant current and are designed with INVERTER technology using components having high performance and high reliability and can use for stick electrode and TIG welding.

2.2 SYSTEM DESCRIPTION

The power supply is built on a single main board with the control logics on separate interchangeable hybrid boards which give the system a very high degree of reliability and simplify maintenance and service.

The power module uses an INVERTER working at a frequency higher than 80 kHz with a very low dynamic response time (500 millisecond) resulting in an extremely smooth welding characteristic which gives easier starting, more homogeneous droplet size, better penetration and smoother bead appearance.

2.6 PROTECTION DEVICES

2.6.1 Overheating and main supply anomalies protection

The power supply is protected by a device installed in such a way as to act in case of overheating and/or main supply anomalies.

When this device intervenes, the unit stops supplying current but the cooling fan keeps working. The acting of the device is shown by the LED turning on (4 in figure 2).

The turning off of the LED signals the resumed ability of the unit to be in operating conditions.

Inverter Power Sources specifications

ARC inverter power sources are essential tools in the field of welding, known for their efficiency, versatility, and advanced technological features. These devices convert direct current (DC) to alternating current (AC), which allows operators to produce high-quality welds with greater control and stability. The evolution of inverter technology has significantly improved the performance of welding equipment, making ARC inverter power sources a popular choice among professionals in various industries.

One of the main features of ARC inverter power sources is their lightweight and compact design. Compared to traditional transformer-based welders, inverter models are significantly smaller and easier to transport, which is particularly beneficial for mobile welding applications. Their portability does not compromise their power output; in fact, many modern inverter welders can deliver high amperage while remaining energy-efficient.

A notable technological advancement in ARC inverter power sources is their use of high-frequency inverter circuits. These circuits enhance the welding process by providing a more stable and consistent arc, reducing the likelihood of defects such as undercutting or spatter. Additionally, the high-frequency operation allows for better control over the heat input, making it easier to weld thin materials without causing warping or burn-through.

Another characteristic of these power sources is their user-friendly interface and adjustable settings. Many models come equipped with digital displays, allowing welders to monitor parameters such as voltage, amperage, and duty cycle in real time. This adaptability ensures that operators can tailor the welding process to suit various materials and thicknesses, improving overall weld quality.

ARC inverter power sources are also designed with built-in safety features, including thermal overload protection and automatic shutdown functions. These safety measures help prevent equipment damage and enhance operator safety, making them suitable for both novice and experienced welders.

Overall, ARC inverter power sources combine advanced technology, ease of use, and robust performance, making them an indispensable asset in the welding industry. As manufacturers continue to innovate, these devices are likely to become even more efficient and versatile, solidifying their place in modern fabrication and construction projects. With their growing range of applications, from automotive repair to heavy industrial work, ARC inverter power sources are revolutionizing the way welding is performed.
