4.1 vaizdas: The welding machine with its standard accessories and approximate dimensions.
4.2 Maitinimo jungtis
The welder supports dual voltage input (110V/220V). Connect the power cable (12) to a suitable power outlet. The machine will automatically detect the input voltage.
4.3 Wire Feeder Installation (for MIG/Flux-Cored Welding)
To install the welding wire for MIG or Flux-Cored operations:

4.2 vaizdas: Diagram of the inner wire feeder mechanism.
- Open the side panel of the welder to access the wire feeder compartment.
- Place the 0.5-1.0KG wire spool onto the spool spindle.
- Secure the spool with the keyed washer and nut, ensuring the spool brake pad is correctly positioned to provide slight tension.
- Feed the welding wire through the wire guide and into the drive rollers.
- Close the drive roller tension arm and adjust the tension as needed.
- Thread the wire through the MIG torch liner until it exits the contact tip.
4.4 Suvirinimo kabelių prijungimas
- Gruntas Clamp: Prijunkite įžeminimą klamp cable to the appropriate terminal on the front panel (Positive or Negative, depending on the welding process and wire type). Secure the clamp prie ruošinio.
- Elektrodų laikiklis (MMA): MMA suvirinimui prijunkite elektrodo laikiklio laidą prie nurodyto gnybto.
- MIG žibintuvėlis: Connect the MIG torch to the MIG torch connection (9).
- TIG degiklis: For Lift TIG welding, connect the TIG torch to the appropriate connection.
5. Veikimo režimai
The PAKROMAN 120A welder offers three primary welding modes: MMA, MIG (Flux-Cored/Gas), and Lift TIG.

5.1 vaizdas: The smart digital display allows for precise adjustment and monitoring of welding parameters.
5.1 Režimo pasirinkimas
Use the mode selection button (2) on the front panel to cycle through the available welding processes: MMA, MIG FLUX/0.8, MIG FLUX/0.9/1.0, and TIG. The digital display (1) will show the selected mode and current settings.
5.2 MMA (Manual Metal Arc) Welding
MMA welding, also known as Stick welding, uses a consumable electrode coated in flux.
- Pasirinkite MMA režimą.
- Prijunkite elektrodo laikiklį prie teigiamo (+) poliaus ir įžeminimo laido.amp to the negative (-) terminal for most common electrodes (check electrode manufacturer specifications).
- Įkiškite tinkamą elektrodą į laikiklį.
- Adjust the current using the control button (7) based on the electrode type and material thickness.
- Strike an arc and maintain a consistent arc length and travel speed.
5.3 MIG (Metal Inert Gas) Welding - Flux-Cored/Gas
MIG welding uses a continuously fed wire electrode. This machine supports both gasless flux-cored wire and gas-shielded MIG welding.
- For Flux-Cored Welding: Select MIG FLUX/0.8 or MIG FLUX/0.9/1.0 mode. Connect the MIG torch to the positive (+) terminal and the ground clamp to the negative (-) terminal. No external shielding gas is required.
- For Gas-Shielded MIG Welding: Select the appropriate MIG mode. Connect the MIG torch to the positive (+) terminal and the ground clamp to the negative (-) terminal. Connect an external shielding gas cylinder (e.g., Argon/CO2 mix) to the gas inlet on the machine (if available, not explicitly shown but implied by "Gas/Gasless").
- Adjust wire feed speed and voltage using the control button (7) according to the material and wire diameter.
- Ensure proper stick-out and torch angle for optimal welds.
5.4 Liftinis TIG suvirinimas
Lift TIG welding provides precise control for high-quality welds.
- Select TIG mode.
- Connect the TIG torch to the negative (-) terminal and the ground clamp į teigiamą (+) gnybtą.
- Įsitikinkite, kad TIG degiklyje yra įmontuotas tinkamas volframo elektrodas.
- Connect an external shielding gas cylinder (e.g., 100% Argon) to the gas inlet.
- Adjust the current using the control button (7).
- To initiate the arc, gently touch the tungsten to the workpiece and then lift it slightly.
