2. Saugos instrukcijos
Welding operations involve significant risks. Always adhere to the following safety guidelines to prevent injury or damage:
- Akių ir veido apsauga: Always wear the provided Red 13 LCD welding helmet or a suitable alternative with appropriate shade protection (9-13) to shield your eyes and face from arc rays and sparks.
- Kūno apsauga: Wear flame-resistant clothing, heavy-duty gloves, and protective footwear. Avoid synthetic materials.
- Vėdinimas: Ensure adequate ventilation in the work area to disperse welding fumes. Welding fumes can be hazardous to health.
- Priešgaisrinė prevencija: Keep a fire extinguisher nearby. Remove all flammable materials from the welding area. Sparks and hot slag can travel.
- Elektros sauga: Ensure the welder is properly grounded. Do not operate in wet conditions. Inspect cables for damage before each use.
- Darbo sritis: Darbo vieta turi būti švari ir tvarkinga. Užtikrinkite stabilų stovėjimą.
- Vaikai ir pašaliniai asmenys: Laikykite vaikus ir neįgaliotus asmenis atokiau nuo suvirinimo zonos.

5.1 Powering On and Current Adjustment
- Maitinimas: Flip the main power switch located on the welder to the 'ON' position. The digital display will illuminate.
- Pasirinkite elektrodą: Choose an electrode suitable for your material and welding thickness (diameter 1.6 to 5 mm).
- Adjust Welding Current: Use the control knob on the front panel to set the desired welding current. The digital display will show the current in Amperes (15-200A). Refer to electrode manufacturer guidelines for recommended current settings.
5.2 MMA suvirinimo procesas
- Saugus ruošinys: Prijunkite įžeminimą klamp securely to the workpiece or a metal workbench that is in direct contact with the workpiece.
- Įdėkite elektrodą: Insert the chosen electrode into the electrode holder.
- Padėtis: Position yourself comfortably and safely. Lower your welding helmet.
- Smūgio lankas: Briefly touch the electrode to the workpiece and quickly lift it slightly to establish an arc. The ARC 250 features HOT FORCE for optimal ignition and ANTI-STICK technology to prevent the electrode from sticking.
- Suvirinimas: Maintain a consistent arc length and travel speed. The ARC 250 is designed for continuous welding (high duty cycle).
- Baigti: Once the weld is complete, lift the electrode from the workpiece. The helmet will return to its light state.
- Išvalyti: Use the wire brush/hammer to remove slag from the weld.
5.3 Generator Compatibility
The AWELCO ARC 250 welder can be connected to a suitable power generator. Ensure the generator provides stable power within the welder's specifications (230V, 50/60Hz, sufficient KVA output, minimum 8.5 KVA recommended) to prevent damage to the welder or inconsistent welding performance.
6. Priežiūra
Regular maintenance ensures the longevity and safe operation of your welding equipment.
- Valymas: Regularly clean the welder's ventilation openings to prevent dust and debris buildup, which can cause overheating. Use compressed air if available.
- Kabelio apžiūra: Periodically inspect all cables (power, ground, electrode) for cuts, fraying, or damaged insulation. Replace damaged cables immediately.
- Terminalo patikrinimas: Ensure all cable connections to the welder are tight and free of corrosion.
- Helmet Care: Clean the helmet's outer and inner lenses with a soft cloth and mild cleaner. Do not use abrasive materials.
- Saugykla: Store the welder and accessories in a dry, clean environment, away from moisture and extreme temperatures.
