Important Safety Instructions
READ THIS WARNING. PROTECT YOURSELF & OTHERS.
Always prioritize safety when operating welding equipment. Failure to follow these instructions can result in serious injury or death.
- ELECTRIC SHOCK CAN KILL: Touching live electrical parts can cause fatal shocks or severe burns. The electrode and work circuit are electrically live when the output is on. The input power circuit and internal machine circuits are also live when power is on. Incorrectly installed or improperly grounded equipment is dangerous. The operator should keep the work piece insulated from himself/herself. Avoid all contact with live electrical parts of the welding circuit, electrodes, and wires with bare hands. The operator must wear dry welding gloves while performing the welding task. Do not operate with panels removed.
- FUMES & GASES CAN BE DANGEROUS TO YOUR HEALTH: Keep your head out of fumes. Use enough ventilation or exhaust at the arc, or both, to keep fumes and gases from your breathing zone and general area.
- WELDING SPARKS CAN CAUSE FIRE OR EXPLOSION: Do NOT weld near flammable material. Do NOT weld on containers which have held flammable material.
- ARC RAYS CAN INJURE EYES AND BURN SKIN: Arc rays are harmful to people's eyes and skin. Always wear a welding helmet with correct shade of filter lens and suitable protective clothing including welding gloves whilst the welding operation is performed.
ONLY QUALIFIED PERSONNEL SHOULD INSTALL, USE OR SERVICE THIS EQUIPMENT. READ AND FOLLOW THE MANUFACTURER'S INSTRUCTIONS, EMPLOYER'S SAFETY PRACTICES AND MATERIAL SAFETY DATA SHEETS (MSDS) FOR CONSUMABLES.
Setup and Installation
1. Power Connection:
- Ensure the welding machine is turned off before connecting to power.
- Connect the power cable to the appropriate 110V or 220V power outlet. The machine automatically detects the voltage.
- Verify that the power source can provide sufficient current for welding operations (refer to specifications).
2. Connecting Welding Cables:
- Ground Clamp: Connect the ground clamp cable to the negative (-) terminal on the front panel. Securely attach the ground clamp to the workpiece or a clean, bare metal part of the welding table.
- Welding Clamp (MMA): For MMA welding, connect the welding clamp cable to the positive (+) terminal.
- MIG Torch: For MIG welding, connect the MIG torch cable to the designated MIG connector (often labeled "MAG" or "MIG"). Ensure it is securely fastened.
- TIG Torch (Lift TIG): For TIG Lift welding, connect the TIG torch to the negative (-) terminal.
3. Wire Installation (MIG/Flux-Cored):
- Open the wire feed compartment.
- Place the spool of flux-cored wire (or solid wire if using gas MIG) onto the spindle.
- Thread the wire through the guide tube and into the drive roller mechanism.
- Close the drive roller tension arm and adjust the tension appropriately.
- Feed the wire through the MIG torch liner until it exits the contact tip.
4. Gas Connection (Optional for MIG, Required for TIG):
- For gas-shielded MIG welding or TIG welding, connect the gas hose from your shielding gas cylinder (e.g., Argon for TIG, Argon/CO2 mix for MIG) to the gas inlet on the welding machine.
- Ensure all connections are tight and leak-free.
- Adjust the gas flow rate at the regulator according to the welding process and material.
Operating Instructions
The Genérico 325A offers three primary welding modes: MMA, MIG, and TIG Lift. Use the digital display and control knobs to select the desired mode and adjust parameters.
1. MMA (Manual Metal Arc) Welding:
- Select "MMA" mode on the digital display.
- Connect the welding clamp to the positive (+) terminal and the ground clamp to the negative (-) terminal.
- Insert the appropriate electrode (welding rod) into the welding clamp.
- Adjust the amperage based on the electrode type and material thickness.
- Strike an arc by lightly touching and then quickly lifting the electrode from the workpiece. Maintain a consistent arc length and travel speed.
2. MIG (Metal Inert Gas) Welding:
- Select "MIG" mode on the digital display.
- Ensure the MIG torch is connected and the wire is properly fed.
- If using gas-shielded MIG, ensure the gas cylinder is open and flow rate is set. For flux-cored wire, no external gas is needed.
- Adjust the voltage and wire feed speed according to the material and wire diameter. These parameters are often linked.
- Position the MIG torch at the desired angle and press the trigger to start welding.
3. TIG (Tungsten Inert Gas) Lift Welding:
- Select "TIG Lift" mode on the digital display.
- Connect the TIG torch to the negative (-) terminal and the ground clamp to the positive (+) terminal.
- Ensure an Argon gas cylinder is connected and the flow rate is set.
- Install a tungsten electrode into the TIG torch.
- Gently touch the tungsten electrode to the workpiece and then lift it slightly to initiate the arc. This is the "Lift Arc" feature, which minimizes tungsten contamination.
- Feed filler rod manually as needed.
Maintenance
Regular maintenance ensures the longevity and safe operation of your welding machine.
- Cleaning: Regularly clean the exterior of the machine with a dry, soft cloth. Use compressed air to blow out dust and debris from the ventilation openings. Ensure the machine is disconnected from power before cleaning.
- Cable Inspection: Periodically inspect all welding cables, power cables, and torch leads for cuts, abrasions, or loose connections. Replace damaged cables immediately.
- Torch Maintenance: For MIG torches, regularly clean the contact tip, nozzle, and diffuser. Replace worn contact tips and nozzles. For TIG torches, inspect and sharpen the tungsten electrode as needed.
- Wire Feed System (MIG): Clean the drive rollers and wire liner to prevent wire feeding issues. Adjust drive roller tension as necessary.
- Storage: Store the welding machine in a clean, dry environment, away from excessive dust, moisture, and corrosive materials.
Troubleshooting
If you encounter issues with your welding machine, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to the machine | Power cable disconnected, circuit breaker tripped, faulty power outlet. | Check power cable connection. Reset circuit breaker. Test power outlet with another device. |
| No arc or weak arc | Poor ground connection, incorrect amperage/voltage settings, worn electrode/contact tip, faulty cable. | Ensure ground clamp is on clean metal. Adjust settings. Replace consumables. Inspect cables for damage. |
| Wire feeding issues (MIG) | Incorrect drive roller tension, clogged liner, wrong size contact tip, tangled wire. | Adjust drive roller tension. Clean or replace liner. Use correct contact tip. Untangle wire spool. |
| Overheat protection activated | Exceeded duty cycle, poor ventilation, high ambient temperature. | Allow machine to cool down. Ensure adequate ventilation around the machine. Reduce welding time. |
If the problem persists after attempting these solutions, please contact customer support.
