2. Sikkerhedsoplysninger

Welding operations involve inherent risks. Adherence to safety precautions is crucial to prevent injury or damage to property. Always consult local safety regulations and standards.

• Elektrisk stød: Welding current can cause fatal electric shock. Ensure proper grounding of the equipment. Wear dry, insulated gloves and protective clothing. Do not touch live electrical parts.
• Røg og gasser: Welding produces fumes and gases that can be hazardous to health. Work in a well-ventilated area or use local exhaust ventilation. Avoid breathing fumes.
• Bue stråler: Arc rays can burn eyes and skin. Always wear a welding helmet with appropriate filter lenses and protective clothing (long sleeves, heavy pants, leather gloves).
• Brand og eksplosion: Welding sparks and hot metal can cause fires or explosions. Keep flammable materials away from the welding area. Have a fire extinguisher readily available.
• Forbrændinger: Hot metal and slag can cause severe burns. Wear protective clothing and handle hot materials with appropriate tools.
• Pacemakere: Individuals with pacemakers should consult their doctor before welding. Electromagnetic fields can interfere with pacemakers.

4. Opsætning

Before operating the welder, ensure proper setup to guarantee safety and optimal performance.

1. Udpakning: Carefully remove the welding machine and all accessories from the plastic carry case. Inspect for any shipping damage.
2. Strømtilslutning: Connect the welder to a suitable 230V AC power supply. Ensure the power outlet is properly grounded and can handle the required current (refer to specifications). If using a motor-generator, ensure it meets the power requirements and benefits from the MPGE multiprotections.
3. Jord Clamp Forbindelse: Fastgør jorden clamp cable to the appropriate terminal on the welding machine (usually marked with a negative (-) symbol or ground symbol). Securely fasten the ground clamp til emnet eller en ren, bar metaldel af svejsebordet, og sørg for god elektrisk kontakt.
4. Electrode Holder Connection (MMA): Connect the electrode holder cable to the positive (+) terminal on the welding machine. Insert the desired electrode into the electrode holder.
5. TIG Torch Connection (Optional, for TIG welding): If performing TIG welding, connect the TIG torch to the appropriate terminal (usually negative (-) for DC TIG) and connect the gas hose to a suitable inert gas cylinder (e.g., Argon) with a regulator.
6. Ventilation: Ensure the welding area is well-ventilated to disperse fumes and gases.
7. Personligt beskyttelsesudstyr (PPE): Always wear appropriate PPE, including a welding helmet, welding gloves, flame-resistant clothing, and safety shoes.

5. Betjeningsvejledning

This section outlines the basic steps for operating the Telwin Tecnica 188 MPGE for MMA and TIG welding.

5.1. MMA (Shielded Metal Arc) Welding

1. Tænd: Turn on the welding machine using the main power switch.
2. Vælg svejsetilstand: Ensure the machine is set to MMA mode (if applicable, some machines auto-detect or have a switch).
3. Indstil strøm: Juster svejsestrømmen (amperage) according to the electrode type and diameter, and the thickness of the material being welded. Refer to electrode manufacturer recommendations.
4. Forbered emnet: Ensure the workpiece is clean, free of rust, paint, and grease.
5. Strike an Arc: With the welding helmet down, gently scratch the electrode tip against the workpiece to initiate the arc. Once the arc is established, maintain a consistent arc length and travel speed.
6. Svejsning: Move the electrode along the joint, maintaining the arc and depositing weld metal.
7. Slutte: When the weld is complete, break the arc by quickly pulling the electrode away. Allow the weld to cool before handling.

5.2. TIG (Tungsten Inert Gas) Welding (Scratch Start DC)

The Tecnica 188 MPGE supports TIG welding with scratch striking. This method requires careful technique to avoid contaminating the tungsten electrode.

1. Power On and Mode Selection: Turn on the welder and select TIG mode.
2. Gasflow: Open the gas cylinder valve and set the gas flow rate on the regulator (typically 5-10 liters/minute for Argon).
3. Indstil strøm: Adjust the welding current for TIG welding based on material thickness and tungsten electrode size.
4. Prepare Tungsten: Ensure the tungsten electrode is properly ground to a sharp point.
5. Scratch Start: With the welding helmet down, gently touch the tungsten electrode to the workpiece and quickly lift it a small distance (1-3mm) to establish the arc. Avoid sticking the tungsten to the workpiece.
6. Svejsning: Maintain a consistent arc length and angle. Feed filler rod into the weld puddle as needed.
7. Slutte: Gradually reduce the arc length or quickly pull the torch away to extinguish the arc. Maintain gas flow over the hot tungsten and weld puddle for a few seconds after the arc stops to prevent oxidation.

6. Vedligeholdelse

Regelmæssig vedligeholdelse sikrer din svejsemaskines lange levetid og sikker drift.

• Rensning: Periodically clean the exterior of the machine with a dry, soft cloth. Ensure ventilation openings are free from dust and debris. Use compressed air to blow out internal dust if necessary, ensuring the machine is unplugged.
• Kabelinspektion: Inspicer regelmæssigt svejsekabler, elektrodeholder og jordforbindelse.amp for damage, cuts, or loose connections. Replace damaged components immediately.
• Electrode Holder/TIG Torch: Clean the electrode holder jaws or TIG torch collet and body. Replace worn parts.
• Opbevaring: Store the welding machine in its plastic carry case in a dry, clean environment, away from moisture and extreme temperatures.
• Professionel service: For internal repairs or complex issues, contact qualified service personnel.

7. Fejlfinding

Dette afsnit omhandler almindelige problemer, du kan støde på med din svejsemaskine.

• Ingen strøm:
  • Check if the power cable is securely plugged in.
  • Verify the main power switch is in the "ON" position.
  • Kontroller afbryderen eller sikringen i dit el-tavle.
• No Arc / Difficulty Striking Arc:
  • Sørg for jorden clamp has good contact with clean, bare metal on the workpiece.
  • Check that the electrode is properly inserted into the holder and is suitable for the material.
  • Verify welding current settings are appropriate.
  • For TIG, ensure gas flow is correct and tungsten is clean and sharpened.
• Dårlig svejsekvalitet:
  • Adjust welding current, arc length, and travel speed.
  • Ensure the workpiece is clean.
  • Use the correct type and size of electrode for the application.
  • For TIG, check gas shielding and tungsten condition.
• Overheating / Thermal Protection Activated:
  • The machine's thermostatic protection may have activated. Allow the machine to cool down.
  • Sørg for tilstrækkelig ventilation omkring maskinen.
  • Reduce the duty cycle or welding current if continuously welding at high amperages.

If problems persist after following these steps, contact Telwin customer support or a qualified service technician.
