Quick Answer

Question: Should I use .30 or .35 welding wire?

The . 030 Flux core wire is easier to use when welding on thinner metals or when you are still learning how to weld. It is mainly because . 035 thickness requires higher amperage.

Can you use 030 wire with a 035 tip?

035 wire with an . 030 tip wouldn’t work because the wire won’t fit through it. The tips are actually called ”contact tips” and that’s how the wire is energized with the power for welding.

What is the best size wire for MIG welding?

Recommended Welding Wire Size Chart

MIG SOLID WIRE GASLESS FLUX-CORED WIRE
MATERIAL THICKNESS .024″ .045″
24 Gauge (.025) X
22 Gauge (.031) X

Is thicker welding wire better?

Thicker wires can often feed at much slower speeds. If you increase your amperage too much, then the arc will become erratic and leave spatter along the weld. When you need to increase your power, then your best bet is to use a thicker wire.

Is flux core better than MIG welding?

Strength of the Weld

Welders will debate whether flux core welding or MIG welding provides a stronger weld until the end of time. The truth of it is that they are ultimately pretty similar. For most applications, both methods will provide a strong weld that will hold what it needs to.

What’s better flux core or MIG?

Is MIG welding with gas better than flux core? If you are working indoors, MIG welds will have the advantage of being more visually appealing and will have no slag to chip off. However, if you are working outside, then flux core welding will be better as it can withstand windy conditions.

What thread are MIG tips?

How do you choose the diameter of a MIG wire?

MIG Welding: What Size Wire Should I Use?

What size wire should I weld with?

It’s always best to size welder circuits and wiring based on the input current requirements of the welder. For example, 240-volt, 40- to 50-input amp welders will require a 50-amp circuit breaker and 6-gauge wiring. Welders operating at 30 to 40 input amps require a 40-amp breaker and 8-gauge wire.

Is .030 or .035 wire better?

The 0.035” cored wire offers slightly more welding power, provides a higher heat input into the metal, and better penetration. Compared to the 0.030” this thicker diameter is used in similar environments. But with a higher flux content, it can better withstand windy conditions.

What gauge is .035 wire?

Wire Gauge Conversion

Wire Number (Gauge) A.W.G. or B&S (Inches) A.W.G. Metric (MM)
33 0.0071″ 0.1803mm
34 0.0063″ 0.1601mm
35 0.0056″ 0.1422mm
36 0.005″ 0.127mm

What size of MIG welder do I need?

How many amps do you really need for a MIG welder? In average you need 140 amps for 115 volts welders in order to weld up to ¼” thick steel and around 200 amps for 220 volts welders and weld up to ½” thick material.

What is a disadvantage of flux-core welding?

The Disadvantages of FCAW

A high level of noxious fumes which must be ventilated. Higher electrode wire cost compared to solid electrode wires. More costly equipment than many other welding processes. Less portable equipment than SMAW or GTAW.

Can you weld aluminum with a flux core?

But no success. The products are solid aluminum or flux core steel wire. They won’t work on aluminum, or needs a shielding gas.

Can I use solid wire in a flux core welder?

You can work continuously to create solid, clean welds that will be neat and visually appealing—that is, if you use a solid wire with shielding gas. While flux cored wire can create a strong weld in thicker metal, you will lose some neatness in the finished weld.

What is the best welder for a beginner?

Are Harbor Freight welders any good?

Harbor Freight has a complete line of high-quality MIG, TIG, Flux and Stick welders. If you’re a seasoned professional, or just getting started, Harbor Freight welders are a great value without compromising features or capabilities.

Can I use flux core in a MIG welder?

Yeah, that will work fine. Flux core is sometimes used in MIG welders even when gas is available. For example, flux core will work in windy conditions that would blow away shielding gas. Also, flux core often gives somewhat better penetration than gas shielded wire.

Are all MIG tips Universal?

It’s highly recommended that to match the contact tip size to the wire size with your MIG gun. Likewise, contact tip threads come in a range of sizes from M6 to M12. These sizes are entirely dependent of the contact tip holder size, but the thread sizes correlate directly to the rating of the MIG gun.

What sizes do the contact tips come in?

Contact tips typically come in one of four recess measurements, ranging from ¼-inch in to ⅛ -inch out. A flush recess (meaning even with the exterior) is a good choice if you’re using gas with a low argon concentration, or 100% CO2 gas. A ⅛ inch extension is best for hard-to-reach joints.

How do you determine what size contact tip should be used for a wire electrode?

Selecting a contact tip with a slightly smaller ID for the wire being used is recommended to ensure the tip/wire interface resistance is low enough that drastic arcing does not occur. For example, a 0.045-in. -diameter solid wire would match well with a contact tip with an ID of 0.049 to 0.050 in.

How many pounds will one inch weld hold?
