Welding Cabinet

The differences between MMA, MIG and TIG are in the principle of operation, ease of use, and suitability to the type of work:

1.MMA welding (electric welding cabinet or incense welding cabinet)

Working principle: Use an electric current, generate heat from the arc between the workpiece and the "rod welding wire" (welding incense), which is covered with flux as an intermediate.

.

Advantages: The cheapest, easy to use, easy to move and carry because it does not require a gas tank.

.

Disadvantages: Spatter has a lot of flakes. You have to knock out the slag after welding. And it is not suitable for thin steel because heat can easily penetrate steel.

.

Suitable for: General Steel Structural Works, Home Fence Repair, Outdoor Construction Works and New DIY Mechanic

.

2.MIG welding (CO2 or MIG welding machine)

Working Principles: Use a roll welding wire that will be automatically fed out of the welding gun, and use gas (such as CO2 or argon) injection cover to protect the welding line.

.

Advantages: Very fast and continuous welding, because the automatic feed wire, the welding line is clean with almost no exchange for knocking, thin steel welding is excellent, and it is the most easily learned system for novice mechanics.

.

Disadvantages: The machine costs more than MMA, the setting is quite complicated, and it is not convenient to move often because the gas tank has to be towed.

.

Suitable for: garage work, furniture assembly work, indoor work (e.g. in a garage), and industrial work that requires a long welding line.

.

3.TIG welding (argon welding machine)

Working Principle: Use a tungsten rod as an arcing generator for heating, and the welder must use the other hand to feed the fill wire into the melting pond, covered by inert gas.

.

Advantages: The most beautiful welds (often come out as fish scale characteristics), the work piece is nib, clean, without splash flakes, and can control heat very accurately.

.

Disadvantages: most difficult to train, slow to work, expensive to machine, and requires very precise hand coordination to control the device.

.

Suitable for: Quality work that relies on high refinement, stainless steel, aluminum, muffler and finishing work that focuses on aesthetics.
