- 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.
- Gaz sizib chiqmasligi uchun barcha ulanishlar mahkam bog'langanligiga ishonch hosil qiling.
- 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)
- Simli g'altak bo'linmasini oching.
- 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. Foydalanish bo'yicha ko'rsatmalar
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 Parameter Adjustment
- 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: Adjust the welding current (amperage) based on the electrode type and diameter.
