2. Informació de seguretat
Welding operations involve significant risks. Always prioritize safety to prevent injury or damage. Adhere to all local safety regulations and guidelines.
2.1 Precaucions generals de seguretat
- Equips de protecció individual (EPI): Always wear a welding helmet with appropriate shade, flame-resistant clothing, welding gloves, and safety shoes. Protect bystanders with welding screens.
- Ventilació: Ensure adequate ventilation to remove welding fumes and gases, which can be hazardous to health. Work in a well-ventilated area or use fume extractors.
- Seguretat elèctrica: Ensure the welding machine is properly grounded. Do not operate in wet conditions. Inspect cables for damage before each use. Never touch live electrical parts.
- Perills d'incendi: Keep flammable materials away from the welding area. Have a fire extinguisher readily available. Welding sparks can travel considerable distances.
- Raigs d'arc: The welding arc produces intense visible and invisible (UV and IR) rays that can burn eyes and skin. Never look at the arc without proper eye protection.
- Àrea de treball: Mantingueu la zona de treball neta i lliure de trastos. Assegureu-vos d'una base estable.
2.2 Product Specific Safety Features
The DEKO 140A Inverter Welder is equipped with multiple protection systems to enhance user safety and product longevity:
- Protecció contra sobreescalfament: Automatically shuts down the machine if internal temperature exceeds safe limits.

5. Instruccions de funcionament
Before operating, ensure you have read and understood all safety information in Section 2.
5.1 Encès
Flip the Power Control Switch on the back panel to the 'ON' position. The Power Indicator Light on the front panel will illuminate, and the digital display will show the current setting.
5.2 Ajust del corrent de soldadura
Use the Welding Current Adjustment Knob on the front panel to set the desired welding current (Amperes). The digital LED display will show the selected value. The appropriate current depends on the electrode diameter and the material thickness being welded.

5.3 Welding Features
The DEKO 140A welder incorporates features to enhance welding performance:
- Inici calent: Provides an automatic boost of current at the start of welding to ensure easier arc ignition and prevent the electrode from sticking.
- Antiadherent: Reduces the welding current if the electrode sticks to the workpiece, allowing for easier removal and preventing damage to the electrode or machine.
- Força de l'arc: Automatically increases the current when the arc length becomes too short, maintaining a stable arc and preventing sticking.
