• 2. Rod Diameter / Wire Diameter: Displays the recommended electrode or wire diameter.
• 3. Plate Thickness: Indicates the recommended material thickness for the selected settings.
• 4. Voltage: Displays the welding voltage.
• 5. Current Value: Displays the welding current (Amperes).
• 6. Parameter Adjustment Knob: Used to fine-tune welding parameters such as current and voltage.

5. Setup

5.1 Wire Installation (Flux Core MIG)

Follow these steps to properly install the flux core welding wire:

Image: An exploded diagram illustrating the components and steps for installing the flux core wire, including the spool lock, spring, spool spacer, flux core wire, and drive roller for 0.8mm/1.0mm wire.

1. Open the wire feed compartment cover on the top of the welder.
2. Place the spool of 0.8mm flux core wire onto the spool holder, ensuring it rotates freely. Use the spool spacer and spring as shown in the diagram.
3. Secure the spool with the spool lock.
4. Thread the wire through the guide tube and into the drive roller mechanism. Ensure the wire is seated correctly in the groove corresponding to its diameter (0.8mm or 1.0mm).
5. Close the drive roller tension arm and adjust the tension. The tension should be firm enough to feed the wire smoothly without slipping, but not so tight that it deforms the wire.
6. Feed the wire through the MIG torch liner until it emerges from the contact tip. You may need to press the torch trigger (with power on and mode selected) to activate the wire feed motor.
7. Ensure the correct conductive nozzle (0.8mm or 1.0mm) is installed on the MIG torch.

5.2 Power Connection

The FEIFANKE MIG Welder 135A supports dual voltage input (110V/220V).

• The machine comes with a standard US 110V NEMA 5-15 plug attached to a 14 AWG cord.
• For 220V operation, use the included adapter cord which has a NEMA 6-50 plug. Note that the adapter cord also uses 14 AWG wire and passes through the 5-15 plug.
• Always connect the welder to a dedicated circuit with appropriate amperage ratings (e.g., 15A or 20A for 110V, higher for 220V as per local electrical codes).
• Ensure the power switch on the welder is in the OFF position before connecting to a power outlet.

6. Operating Instructions

6.1 General Operation

1. Connect the ground clamp to the workpiece, ensuring good electrical contact.
2. Turn on the welder using the power switch.
3. Select the desired welding mode (MIG, ARC, or Lift TIG) using the mode selection button on the control panel.
4. Adjust welding parameters using the parameter adjustment knob. The digital display will show current, voltage, and recommended settings.

6.2 Flux Core MIG Welding

This mode is suitable for welding carbon and stainless steel from 1mm to 5mm thickness.

Image: The control panel displaying settings for MIG welding mode. It shows pressing to choose FLUX CORE Φ0.8, rotating to select welding current, and a recommendation of 4.5mm plates for 135A output.

1. Select the Flux Core MIG mode.
2. Use the parameter adjustment knob to set the desired welding current. The machine features synergistic control, meaning wire feed speed will adjust automatically with current.
3. Before starting a weld, trim the welding wire so it protrudes only slightly from the contact tip. This helps prevent the wire from bending before the arc is established.
4. Position the MIG torch at the starting point of the weld.
5. Press the torch trigger to initiate the arc and begin welding. Maintain a consistent travel speed and torch angle.

6.3 ARC (Stick) Welding

This mode uses covered electrodes (welding rods).

1. Select the ARC mode on the control panel.
2. Connect the electrode holder to the positive (+) terminal and the ground clamp to the negative (-) terminal (or vice-versa depending on electrode type).
3. Insert a welding rod into the electrode holder.
4. Adjust the welding current using the parameter adjustment knob according to the electrode type and material thickness.
5. Strike the arc by lightly touching and quickly lifting the electrode from the workpiece.

6.4 Lift TIG Welding

This mode provides precise welding for various metals. A TIG torch is required and sold separately.

1. Select the Lift TIG mode on the control panel.
2. Connect the TIG torch (purchased separately) and ground clamp according to the TIG torch's instructions.
3. Adjust the welding current.
4. Touch the tungsten electrode lightly to the workpiece and then lift it slightly to initiate the arc.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your welder.
