2. Veiligheidsinformatie

WAARSCHUWING: Welding can be dangerous. Always follow safety precautions to prevent injury or death. Read and understand all safety information before operating this equipment.

• Elektrische schok: Kan dodelijk zijn. Raak geen stroomvoerende elektrische onderdelen aan. Draag droge lashandschoenen en beschermende kleding. Zorg ervoor dat het werkstuk goed geaard is.
• Dampen en gassen: Kan schadelijk zijn voor uw gezondheid. Houd uw hoofd uit de buurt van de dampen. Gebruik ventilatie of afzuiging om de dampen uit de ademzone te verwijderen.
• Boogstralen: Can burn eyes and skin. Wear a welding helmet with a proper shade filter. Wear protective clothing to cover exposed skin.
• Brand en explosie: Lasvonken kunnen brand of een explosie veroorzaken. Houd brandbare materialen uit de buurt van de lasplek. Zorg dat er een brandblusser binnen handbereik is.
• Hete onderdelen: Kan ernstige brandwonden veroorzaken. Laat het apparaat afkoelen voordat u het aanraakt.
• Lawaai: Overmatig lawaai kan gehoorschade veroorzaken. Draag gehoorbescherming.
• Pacemaker: Magnetische velden van hoge stroomsterktes kunnen pacemakers beïnvloeden. Raadpleeg uw arts voordat u gaat lassen.

Het frontpaneel omvat:

• Digitaal beeld: Shows welding parameters such as current and voltage.
• Modusselectieknoppen: For choosing MIG-MAG, MMA, or TIG Lift welding.
• Parameterinstelknoppen: To fine-tune welding current, voltage, and other settings.
• Uitgangsklemmen: Connections for welding torch and earth clamp.
• Wire Feeder Mechanism: For MIG-MAG welding wire spool and feeding.

3.2 Meegeleverde accessoires

Figuur 3: The included MIG-MAG torch and the 3-meter earth clamp cable. These are essential for starting MIG-MAG welding operations.

The welder is supplied with:

• MIG-MAG Torch (3 meters)
• Aarde Clamp Cable (3 meters)

Opmerking: An electrode holder and TIG torch are not included and must be purchased separately for MMA and TIG Lift welding, respectively.

4. Installatie en installatie

Before beginning any setup, ensure the welder is switched off and disconnected from the main power supply.

4.1 Stroomaansluiting

• Connect the welder to a 230V single-phase power supply. The machine is designed to operate within a voltage range of 230V +/- 15%.
• Ensure the power outlet is properly grounded and capable of supplying the required current (16A fuse recommended).
• The Bester 190C is compatible with sufficiently powerful generators.

4.2 Laskabels aansluiten

• Aarde Clamp: Sluit de aardingsklem aanamp cable to the appropriate terminal on the front panel. Attach the clamp stevig aan het werkstuk bevestigen, zodat een goed elektrisch contact gegarandeerd is.
• MIG-MAG Torch: Connect the MIG-MAG torch to its designated connector on the front panel. Ensure it is firmly seated.
• MMA/TIG (Optional): If using MMA or TIG Lift, connect the electrode holder or TIG torch to the appropriate terminals (positive or negative, depending on polarity requirements for the specific process and electrode/filler material).

4.3 Gas Connection (for MIG-MAG and TIG)

• Connect the gas hose from your shielding gas cylinder (e.g., Argon/CO2 mix for MIG, pure Argon for TIG) to the gas inlet on the welder.
• Zorg ervoor dat alle aansluitingen goed vastzitten om gaslekkages te voorkomen.
• Set the gas flow rate according to your welding process and material requirements using a flowmeter on the gas cylinder regulator.

4.4 Wire Loading (for MIG-MAG)

• Open het compartiment voor de draadspoel.
• Place the wire spool (max 5 kg, 200 mm diameter) onto the spindle, ensuring it rotates freely.
• Feed the welding wire through the guide tube and into the drive rollers.
• Close the drive roller tension arm and adjust the tension. The wire should feed smoothly without slipping or deforming.
• With the torch pointed away from yourself and others, press the trigger to feed the wire through the torch liner until it exits the contact tip.
• The welder supports wire diameters from 0.6 mm to 1.0 mm.

5. Gebruiksaanwijzing

The Bester 190C offers three welding processes: MIG-MAG, MMA, and TIG Lift.

5.1 Process Selection

• Schakel het lasapparaat in met de hoofdschakelaar.
• Use the mode selection buttons on the front panel to choose your desired welding process: MIG-MAG, MMA, or TIG Lift. The selected mode will be indicated on the digital display.

5.2 Parameteraanpassing

• MIG-MAG: Adjust the welding current (wire feed speed) and voltage using the dedicated knobs. Refer to welding charts for recommended settings based on material thickness and wire type. The machine allows for easy polarity inversion.
• MMA: Pas de lasstroom aan (ampleeftijd) op basis van het elektrodetype en de diameter.
• TIG Lift: Adjust the welding current. TIG Lift arc starting requires touching the tungsten electrode to the workpiece and then lifting it slightly to initiate the arc.

5.3 Geavanceerde functies

The Bester 190C includes features to enhance welding performance:

• Boogkracht: Automatically adjusts the welding current to prevent the electrode from sticking during MMA welding, improving arc stability.
• Goede start: Provides an initial boost of current at the start of MMA welding to ensure easy arc ignition.
• Anti-aanbaklaag: Reduces the current if the electrode sticks to the workpiece during MMA welding, making it easier to detach and preventing overheating.

6. Onderhoud

Regular maintenance ensures the longevity and optimal performance of your welding machine. Always disconnect the welder from the power supply before performing any maintenance.

• Schoonmaak: Periodically clean the exterior of the machine with a dry, soft cloth. Use compressed air to blow out dust from inside the machine, especially around cooling vents, but ensure the air is dry and oil-free.
• Kabelinspectie: Regularly inspect all welding cables, power cords, and gas hoses for cuts, abrasions, or damage. Replace damaged components immediately.
• Onderhoud van de brander: For MIG-MAG, regularly clean the contact tip, gas nozzle, and check the wire liner for blockages or wear. Replace consumables as needed. For TIG, inspect the tungsten electrode and sharpen or replace as necessary.
• Drive Rollers (MIG-MAG): Clean the drive rollers and ensure they are free of wire debris. Check for proper tension.
