5. Setup

5.1 Power Connection

The ARCCAPTAIN MIG135 operates on 110V AC power. Ensure your power source meets the machine's requirements.

• Connect the power cord to a grounded 110V outlet.
• Verify the power switch on the back of the unit is in the OFF position before connecting.

5.2 MIG Welding Setup (Flux Core Gasless)

1. Install Flux Core Wire: Open the wire feed compartment. Place the flux core wire spool onto the spindle. Thread the wire through the guide and into the drive roller mechanism. Ensure the correct groove on the drive roller is selected for your wire size (e.g., .030" or .035").
2. Connect MIG Gun: Attach the MIG gun cable to the positive (+) terminal on the front panel.
3. Connect Ground Clamp: Attach the ground clamp cable to the negative (-) terminal on the front panel. Secure the ground clamp to the workpiece or welding table, ensuring good electrical contact.
4. Feed Wire: With the MIG gun pointed away from yourself and others, press and hold the trigger to feed the wire through the gun liner until it exits the contact tip.
5. Install Contact Tip: Once the wire is fed, install the appropriate contact tip (.030" or .035") and nozzle onto the MIG gun.

5.3 Lift TIG Welding Setup (Optional)

A Lift TIG torch is required and sold separately for this mode.

1. Connect TIG Torch: Connect the TIG torch cable to the negative (-) terminal on the front panel.
2. Connect Ground Clamp: Attach the ground clamp cable to the positive (+) terminal on the front panel.
3. Gas Connection: If using shielding gas (e.g., 99.9% Argon), connect the gas hose from your regulator to the gas inlet on the machine (if applicable, consult TIG torch manual for specific connections).
4. Install Tungsten: Insert the appropriate tungsten electrode into the TIG torch collet and tighten.

5.4 MMA (Stick) Welding Setup

1. Connect Electrode Holder: Attach the electrode holder cable to the positive (+) terminal on the front panel.
2. Connect Ground Clamp: Attach the ground clamp cable to the negative (-) terminal on the front panel.
3. Insert Electrode: Securely insert the welding electrode into the electrode holder.

6. Operating Instructions

6.1 Powering On and Mode Selection

1. Ensure all connections are secure.
2. Turn the power switch to the ON position. The LED display will illuminate.
3. Use the "Welding Mode" button to cycle through Flux Core MIG, Lift TIG, and MMA (Stick) modes.

6.2 Flux Core MIG Welding

This mode is ideal for general fabrication and repairs without the need for external shielding gas.

• Synergistic Settings (Beginner Friendly):
  • Select the wire size (.030", .035", or .040") and metal thickness on the display.
  • The machine will automatically set recommended wire feeding speed and voltage.
• Manual Adjustment (Experienced Welders):
  • Adjust the wire feeding speed (30-260 IPM) using the main knob.
  • Fine-tune the voltage between -1V and +1V using the voltage trimming function.
  • Select "2T" (two-touch) for standard trigger operation or "4T" (four-touch) for continuous welding without holding the trigger.
• Welding Process: Position the MIG gun at the start of your weld. Press the trigger to initiate the arc and begin welding. Maintain a consistent travel speed and gun angle.
