What are the 7 common mistakes in MIG welding?

There are 7 common mistakes people make when they start MIG welding:

• They don’t prep their material.
• Volts too high or too low.
• Wire feed speed too high or too low.
• Electrical stick-out that is too long or short.
• Gas Flow too low or high.
• Travel speed too fast or slow.
• Gun angle to steep.

Why does my MIG welder sputter?

When the power source senses the reduced current at the arc, it sends a surge of voltage in order to overcome the restricted current flow. This increased voltage causes the popping and sputtering that leads to poor and inconsistent weld quality.

Why is my wire feed welder not working?

Because of its lengthy contact with the wire, a dirty, kinked, clogged, or otherwise damaged liner will almost always cause feeding problems. Make sure you’re using the right MIG liner size for your wire, and choose a high-quality liner that maintains a consistent diameter throughout.

What is wrong with my MIG welder?

Several issues in the MIG welding process can contribute to excessive spatter, including: Insufficient shielding gas. Dirty base materials, contaminated or rusty weld wire. Voltage or travel speeds that are too high.

How important is a good electrical ground in MIG welding?

Maintaining proper grounding within the arc welding setup is vital to safety within the workspace. Another reason to ground is to improve the quality of your welds. This means that if your connection isn’t great, the performance of the welding machine will suffer, which will result in inferior weld quality.

How do I stop my spatter from MIG welding?

To reduce MIG welding spatter, your wire must be fed continuously at the proper tension, with no snagging or other restrictions. A smooth, consistent wire feed speed must be provided to achieve a clean weld. The shielding gas must flow freely at the right rate.

What will cause a wire to feed erratically?

Erratic wire feeding A worn out or kinked liner, or build-up of debris, filings, dirt and other foreign material inside the welding liner, the wrong size liner and misalignments or gaps at the liner junctions caused by an improperly trimmed liner can all cause the wire to feed erratically.

What can occur if a gun liner is dirty or damaged?

A worn out or kinked liner, or build-up of debris, filings, dirt and other foreign material inside the welding liner, the wrong size liner and misalignments or gaps at the liner junctions caused by an improperly trimmed liner can all cause the wire to feed erratically.

What are the disadvantages of beveling plates for welding?

There are several disadvantages of having to bevel a plate before welding: 1- Beveling the edge of a plate adds an operation to the fabrication process. FCA welds with 100% joint penetration can be made in plates up to what thickness?

Why is my MIG welder not sparking?

One of the most common reasons your welder won’t spark is because the connection points between the welder and the metal pieces are not clean or clear. This means that both the workpiece where you want to form an arc as well as the connection point for the work lead clamp need to be bare metal.

Do MIG welders wear out?

A lot of MIG guns are durable and can withstand day-to-day use, but they can still become damaged; sometimes without you even knowing. It is a good practice to perform routine maintenance, and inspect all of your welding equipment before you start work for the day.

How many century MIG welding machines are there?

We are not sure how many were produced, but they were, and still are, simple rugged little machines. Because most welding supplies and welding machine repair companies will not service the Century brand, we offer technical help and parts.

What kind of wire does a century wire feed welder use?

The Century Wire Feed 255 Flux-Cored/MIG Wire Feed Welder built for the professional. With twelve heat settings which allow you to weld from 20 ga. sheet metal up to 3/16” steel in a single pass. Welds 18ga. to 3/16″ using Flux-Cored Wire in a single pass and to 5/16″ in Multi Pass. Easily weld MIG with the addition of SUPERARC® L-56 wire.

What kind of wire does a goplus MiG 130 use?

The Goplus takes 1 or 2 lb. size spools of flux core welding wire. These are also known as 4 inch spools. The Goplus MIG 130 uses 0.030 or 0.035 diameter flux core wire. Given the limited power output of this entry level flux core welder, you may find welding with 0.030 diameter flux core easier.
