Parentah Operasi
This section outlines the general operating procedures for the MIG, TIG, and MMA welding modes.
Léngkah-léngkah Operasi Umum:
- Pastikeun sadaya sambungan aman sareng leres pikeun prosés las anu dipilih.
- Turn on the main power switch on the rear panel of the welder.
- Select the desired welding mode (MIG, MMA, or TIG) using the Modes Switch on the front panel.
- Adjust the Current and Voltage according to the material thickness and welding process. Refer to welding charts for recommended settings.
- For MIG welding, adjust the Wire Speed.
- Put on all necessary PPE.
- Mimitian las.
- After welding, turn off the welder and disconnect from the power supply.
MIG Welding (Gas Metal Arc Welding)
MIG welding is suitable for various metals and offers high productivity. It can be performed with or without shielding gas (flux-cored wire typically does not require external gas).
- Flux-Cored Wire: If using flux-cored wire, external shielding gas is generally not required as the flux provides its own shielding.
- Kawat padat: If using solid wire, connect a suitable shielding gas (e.g., Argon/CO2 mix for steel, pure Argon for aluminum) to the welder.
- Adjust wire speed and voltage for optimal arc stability and bead appearance.

TIG Welding (Gas Tungsten Arc Welding)
TIG welding provides precise, high-quality welds, especially for thin materials and exotic metals. It requires a separate TIG torch and shielding gas (typically pure Argon).
- Connect the TIG torch and ensure the gas supply is connected and flowing.
- Use a non-consumable tungsten electrode.
- Adjust current settings for precise control.
MMA Welding (Manual Metal Arc Welding / Stick Welding)
MMA welding is versatile and suitable for outdoor use and welding on rusty or dirty surfaces. It uses a consumable electrode (stick).
- Connect the electrode holder with the appropriate electrode.
- Adjust the current based on the electrode type and diameter.

Tip pamaké
Based on common user experiences and best practices, consider the following tips for optimal performance:
- Setélan Latihan: Before starting a critical project, practice on scrap pieces of the same material and thickness to fine-tune your current, voltage, and wire speed settings.
- Kabersihan teh konci utama: Always ensure your workpiece is clean and free of rust, paint, or oil for the best weld quality and to minimize spatter.
- Consumable Management: Keep a supply of spare contact tips, nozzles, and electrodes. Replace them as soon as they show signs of wear to maintain consistent weld quality.
- Ventilasi: Even with flux-cored wire, good ventilation is crucial. Consider using a fume extractor or working in an open area.
- Duty Cycle Awareness: Pay attention to the welder's duty cycle. Overheating can occur if you weld continuously for too long. Allow the machine to cool down as needed.
