4. Setup

4.1 Unpacking and Inspection

1. Carefully remove the welding machine and all accessories from the packaging.
2. Inspect all components for any signs of damage during transit. Contact your dealer immediately if any damage is found.
3. Ensure all listed accessories are present.

4.2 Electrical Connection

• Connect the machine to a suitable power supply as specified in the technical specifications. Ensure the power outlet is properly grounded.
• Use an appropriate circuit breaker for the machine's current draw.

4.3 Gas Connection (for WIG welding)

• Connect the gas hose from the welding machine to your shielding gas cylinder (e.g., Argon).
• Attach the gas pressure regulator to the cylinder and set the appropriate gas flow rate (typically 6-12 liters/minute for WIG).
• Ensure all gas connections are tight to prevent leaks.

4.4 Torch and Ground Clamp Connection

• Connect the TIG torch to the designated connector on the front panel.
• Connect the ground clamp cable to the appropriate terminal and securely attach the clamp to the workpiece or welding table, ensuring good electrical contact.
• For MMA welding, connect the electrode holder to the positive (+) terminal and the ground clamp to the negative (-) terminal for most electrodes, or vice-versa depending on electrode type.

5. Operating Instructions

The STAHLWERK AC/DC WIG 200 Puls Pro features a clear and intuitive digital control panel for setting welding parameters.

Figure 5.1: Digital control panel with various settings for AC and Pulse parameters, mode selection, and job memory functions.

5.1 Control Panel Overview

The control panel allows you to select welding modes and adjust parameters:

• Mode Selection: Buttons for DC, AC, MMA, TIG, TIG-R (TIG with remote).
• Digital Display: Shows current welding amperage and other selected parameters.
• Parameter Adjustment Knobs: Used to fine-tune settings such as AC frequency, AC balance, pulse current, pulse frequency, hot start, and crater fill.
• Job Memory (PROG/SAVE): Allows saving and recalling up to 10 custom welding programs.
• 2T/4T Function: Select between 2-stroke and 4-stroke torch operation.
• SPOT Function: Activates the spot welding mode.

5.2 WIG Welding (TIG)

WIG welding offers high precision and clean welds. The machine supports both DC WIG (for steel, stainless steel, copper) and AC WIG (for aluminum and its alloys).

• DC WIG: Select 'DC' mode. Adjust welding current, gas pre-flow, and post-flow.
• AC WIG: Select 'AC' mode. Adjust welding current, AC frequency, AC balance (for cleaning action), gas pre-flow, and post-flow.
• Pulse WIG: Activate 'PULS' function. Adjust pulse current, base current, pulse frequency, and pulse width for controlled heat input, especially on thin materials.
• Spot WIG: Activate 'SPOT' function for precise tack welding.

5.3 ARC/MMA Welding

For electrode welding, select the 'MMA' mode. The machine's Hotstart, Stable Arc, and Anti-Stick functions assist in achieving optimal results.

• Connect the electrode holder and ground clamp as described in Section 4.4.
• Select 'MMA' mode.
• Adjust the welding current according to the electrode type and material thickness.
• The Hotstart function automatically increases voltage for easier arc ignition.
• The Anti-Stick function prevents the electrode from sticking to the workpiece.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your welding machine.

• Cleaning: Regularly clean the machine's exterior with a dry, soft cloth. Use compressed air to blow out dust from the cooling vents. Ensure the machine is disconnected from power before cleaning.
• Check Connections: Periodically inspect all electrical and gas connections for tightness and signs of wear or damage. Replace any damaged cables or hoses immediately.
• Torch Maintenance: Clean the TIG torch regularly. Replace worn-out consumables such as ceramic nozzles, collets, and tungsten electrodes.
• Ground Clamp: Ensure the ground clamp is clean and makes good electrical contact with the workpiece.
• Storage: Store the welding machine in a dry, dust-free environment when not in use.
