3.2 אביזרים כלולים
איור 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)
- כדור הארץ Clamp כבל (3 מטרים)
פֶּתֶק: An electrode holder and TIG torch are not included and must be purchased separately for MMA and TIG Lift welding, respectively.
4. התקנה והתקנה
Before beginning any setup, ensure the welder is switched off and disconnected from the main power supply.
4.1 חיבור מתח
- 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 חיבור כבלי ריתוך
איור 4: The Bester 190C Welder with the MIG torch and earth clamp properly connected to the front panel terminals, ready for operation.
- כדור הארץ Clamp: חבר את האדמה clamp cable to the appropriate terminal on the front panel. Attach the clamp לחבר היטב לחומר העבודה, תוך הבטחת מגע חשמלי טוב.
- 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.
- ודאו שכל החיבורים מהודקים היטב כדי למנוע דליפות גז.
- 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)
- פתח את תא סליל החוט.
- 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. הוראות הפעלה
The Bester 190C offers three welding processes: MIG-MAG, MMA, and TIG Lift.
5.1 Process Selection
- Turn on the welder using the main power switch.
- 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 כוונון פרמטרים
- 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: כוונן את זרם הריתוך (amperage) based on the electrode type and 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 תכונות מתקדמות
The Bester 190C includes features to enhance welding performance:
- כוח קשת: Automatically adjusts the welding current to prevent the electrode from sticking during MMA welding, improving arc stability.
- התחלה חמה: Provides an initial boost of current at the start of MMA welding to ensure easy arc ignition.
- נגד הידבקות: Reduces the current if the electrode sticks to the workpiece during MMA welding, making it easier to detach and preventing overheating.
6. תחזוקה
תחזוקה שוטפת מבטיחה את אורך חייה וביצועיה האופטימליים של מכונת הריתוך שלכם. יש לנתק תמיד את הרתכת מאספקת החשמל לפני ביצוע כל תחזוקה.
- ניקוי: 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.
- בדיקת כבלים: Regularly inspect all welding cables, power cords, and gas hoses for cuts, abrasions, or damage. Replace damaged components immediately.
- תחזוקת לפיד: 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.
