Belajar Pengelasan MIG tanpa Gas Tambahan CO2 | ( FLUX CORE ) | IZUMI MIG 130

Summary

In this tutorial, the process of MIG welding without CO2 gas, also known as FCAW (Flux-Cored Arc Welding), is demonstrated using the Izumi Mix 130 welding machine. The video covers key aspects, such as wire installation, machine setup, and the importance of maintaining the correct polarities for different wire types. It also delves into the specific settings for welding different materials, including thin hollow steel and rebar, showcasing the machine's performance and ease of use. The tutorial emphasizes the advantages of FCAW in welding efficiency and application in fabrication projects like gates and canopies.

Takeaways

• 😀 The video explains the MIG welding process without CO2 gas, also known as Flux-Cored Arc Welding (FCAW).
• 😀 The equipment used in the demonstration is the Izumi Mix 130 MIG welder with a 1kg wire capacity.
• 😀 The welding wire used is Daiden E71T-11 flux-cored wire, which does not require an external shielding gas like CO2.
• 😀 There are two types of FCAW: self-shielding (no external gas) and gas-shielded (uses CO2, argon, or a combination).
• 😀 The process involves installing the welding wire into the welder’s wire feeder, adjusting the wire speed, and setting the correct voltage.
• 😀 The welder's wire feeder has two slots for different wire diameters: 0.8mm and 0.9mm.
• 😀 Polarities for different types of welding wires are important; self-shielding flux-cored wires require DCEN (negative electrode).
• 😀 The welder has two knobs: one for adjusting the wire speed in MIG mode and another for adjusting voltage or amperage in other modes like TIG or MMA.
• 😀 The first step in welding is to practice controlling the wire ignition and maintaining a stable distance between the wire and the workpiece.
• 😀 The video emphasizes the importance of regular maintenance, such as cleaning the nozzle and contact tip, to prevent wire jams and ensure smooth operation.

Q & A

What is the focus of the video on the Izumi Mix 130 welding machine?

The video focuses on teaching the process of MIG welding without additional CO2 shielding gas, also known as FCAW (Flux-Cored Arc Welding), using the Izumi Mix 130 welding machine.

What type of welding wire is used in the video for the welding process?

The welding wire used is the Daiden E71T-11, which is a self-shielding flux-cored wire that does not require additional shielding gas like CO2.

How is the flux-cored arc welding (FCAW) process different from MIG and MAG welding?

FCAW is different because the welding wire itself contains flux that generates a shielding gas during the welding process, unlike MIG/MAG welding, which requires external shielding gas. FCAW can be done with or without additional shielding gas.

What is the function of the wire feeder in the welding machine?

The wire feeder is used to feed the welding wire into the welding torch, allowing a continuous supply of wire to the weld pool during the process.

What are the main components of the welding torch used in the Izumi Mix 130?

The welding torch consists of a contact tip, nozzle tip holder, and a swan neck, all of which are used to guide the welding wire and create the arc.

How is the wire speed adjusted on the Izumi Mix 130 welding machine?

The wire speed is adjusted using one of the two knobs on the machine. One knob controls the speed of the welding wire in MIG mode, while the other controls the current in TIG or MMA modes.

What is the correct polarity for welding with flux-cored wire?

For flux-cored wire (E71T-11), the correct polarity is DC Negative, where the torch is connected to the negative terminal, and the ground clamp is connected to the positive terminal.

What should be the distance between the welding wire and the workpiece during welding?

The distance between the welding wire and the workpiece should be maintained carefully, not too far to avoid excessive wire extension and not too close to prevent the wire from sticking or causing burn-through.

What are the potential causes of wire feeder issues, and how can they be resolved?

Wire feeder issues, such as the wire not feeding when the trigger is pressed, can occur if the wire has expanded due to heat or if there is dirt or blockage in the contact tip. The solution is to clean the contact tip and feed the wire again after cutting any jammed sections.

How does the welding machine handle different material thicknesses?

The welding machine adjusts the wire speed and voltage based on the material thickness. For thinner materials like 1mm hollow steel, lower settings are used, while thicker materials require higher voltage and wire speed for deeper penetration and a wider weld pool.
