5. Setup Instructions

5.1 Power Connection

Connect the welder to a suitable power source. The machine automatically detects and adapts to both 110V and 220V inputs. Use the provided adapter cord if necessary for 110V operation. Ensure the power outlet is properly grounded and capable of supplying the required amperage.

5.2 Wire Installation

Open the wire feed compartment. Place the wire spool onto the spindle and secure it. Thread the welding wire through the appropriate drive roller groove and into the torch liner. Ensure the drive roller matches the wire type:

• K-groove: For Flux welding wire.
• V-groove: For Solid welding wire.
• U-groove: For Aluminum welding wire (AlMg5356).

Figure 5.2: Illustration of the wire feeding system, showing the placement of the wire spool and the three types of drive rollers: K-groove for flux wire, V-groove for solid wire, and U-groove for aluminum wire. Proper selection of the drive roller is crucial for consistent wire feeding.

5.3 Gas Connection (for Gas MIG/MAG)

For Gas MIG/MAG welding, connect your shielding gas cylinder (e.g., Argon/CO2 mix for MAG, pure Argon for Aluminum MIG) to the gas inlet on the rear of the machine using the provided gas hose. Ensure all connections are tight to prevent leaks. WARNING: Use correct gas (Ar/CO2/Ar+CO2) ONLY. Use of incorrect gas can lead to serious injury.

5.4 TIG Torch Connection

Connect the WP-17V TIG welding torch to the designated quick connector (10-25mm²) on the front panel. Ensure the gas hose from the TIG torch is also connected to the gas output on the machine if using shielding gas for TIG welding.

5.5 Ground Clamp and Electrode Holder Connection

Connect the ground clamp cable to the negative (-) terminal and the electrode holder cable (for Stick welding) or MIG torch cable to the positive (+) terminal on the front panel. Always ensure a good electrical connection for the ground clamp to the workpiece.

6. Operating Instructions

6.1 Control Panel and LED Display

The welder features a large LED display for clear visibility of settings. The main knob allows for adjustment of welding parameters. Press and hold button "A" for 3 seconds to activate SYNERGIC mode. The knob "B" can also function as a button. To switch between Amp and Voltage adjustment, select VRD/Arc Force/Hot Start and then press and hold the knob for 3 seconds.

Figure 6.1: Detailed view of the welder's large LED display and control panel. It shows the digital readouts for voltage and amperage, indicators for different welding modes (Flux, Stick, Lift TIG, CO2/MIX, ALMG), and the main adjustment knob with its integrated button functionality for switching between amperage and voltage adjustments.

6.2 Mode Selection

Use the mode selection buttons on the control panel to choose your desired welding process: Gas MIG, Aluminum MIG, Gasless Flux Core MIG, Lift TIG, or Stick welding. The selected mode will be indicated on the LED display.

6.3 SYNERGIC Mode

In SYNERGIC mode, the welder automatically sets optimal voltage and wire feed speed based on the selected amperage and material. This simplifies setup and provides consistent weld quality. To activate, press and hold button "A" for 3 seconds.

6.4 2T/4T/SPOT Settings

These settings provide control over the torch trigger operation:

• 2T (Two-Touch): Press and hold the trigger to weld, release to stop. Ideal for short welds.
• 4T (Four-Touch): Press and release to start welding, press and release again to stop. Suitable for long welds, reducing hand fatigue.
• SPOT: Allows for timed spot welds. The spot time can be adjusted.

Figure 6.4: Visual representation of the 2T, 4T, and SPOT welding settings. 2T involves holding the trigger, 4T allows for continuous welding with two presses, and SPOT enables timed spot welds, catering to diverse welding requirements.

6.5 Aluminum MIG Welding

The AZZUNO MIG-155L simplifies aluminum MIG welding. For best results, use ER5356 AlMg welding wire with a recommended diameter of .040". No Teflon liner or Spool Gun is required. Position the welding torch facing left and weld from right to left for optimal bead formation.

Figure 6.5: Demonstration of aluminum MIG welding with the AZZUNO MIG-155L. The image highlights that a Teflon tube and Spool Gun are not required, simplifying the process. It also recommends using ER5356 AlMg welding wire with a .040" diameter and specific torch positioning.

6.6 Manual Wire Feed Button

The manual WIRE FEED BUTTON allows you to quickly feed the welding wire without initiating an arc. Press and hold this button to advance the wire, useful for loading new spools or clearing blockages.
