Quick Answer

Frequent Question Which is better .030 or .035 flux core wire?

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 do I set my wire welder to?

Select proper wire size according to amperage.

  1. 30-130 amps: .023 inch.
  2. 40-145 amps: .030 inch.
  3. 50-180 amps: .035 inch.
  4. 75-250 amps: .045 inch.

What voltage should my MIG welder be set at?

The voltage and wire feed speed vary though. A 0.024-inch wire would operate at 13 to 15 volts (electrode positive) with a wire feed speed of 130 to 160 ipm, whereas the 0.30-inch solid wire would require 15 to 17 volts and 75 to 100 ipm wire feed speed.

What is the tensile strength of .035 flux core wire?

Tensile strength is 79,000 PSI.

Can you use .030 wire with a .035 tip?

Mig Welding Tip #8 of the best 19 Mig Welding Tips

Using . 030 drive rollers with . 035 flux core innershield can really just piss you off and make you want to quit welding.

What size flux core wire is best?

030-inch diameter is a good all-around choice for welding a wide range of metal thicknesses. For welding thicker material at higher total heat levels, use . 035-inch wire (or . 045-inch wire if it’s within your welder’s output range).

How do you set up a flux core welder?

How to Set Up your MIG Welder for Flux Cored Welding

What angle is best for welding?

In the horizontal welding position, a work angle of 30 to 60 degrees works well, depending on the type and size of the joint. The goal is to prevent the filler metal from sagging or rolling over on the bottom side of the weld joint.

What happens if the wire feed speed is set too high?

Conclusion. Getting the correct Wire Feed Speed on a Mig Welder is critical to getting a good quality weld. Too little wire feed will generate a weak flat weld, possibly with undercut.

How do you set the wire speed on a MIG welder?

MIG Welder Settings: MIG Welding Basics for Beginners

What is the voltage of a welder?

As the welding processes require high current (50-300A) at relatively low voltage (10-50V),the high voltage mains supply (230 or 400V) must be reduced by a transformer.

How many amps do I need to weld 1/8 steel?

The correct current, or amperage, setting primarily depends on the diameter and type of electrode selected. For example, a 1/8-inch 6010 rod runs well from 75 to 125 amps, while a 5/32-inch 7018 rod welds at currents up to 220 amps.

Can you weld galvanized steel with flux core?

Flux-cored wires can weld galvanized steel, even if you don’t remove the coating.

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.

Can I use solid welding wire in a flux core welder?

Solid wire, self-shielded flux-cored wire and gas-shielded flux-cored wire all work well — provided they are applied correctly. The type of wire you choose will be contingent upon the location of the jobsite, thickness of the application, proper shielding gas combination and the type of equipment available.

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.

What size wire should I use for MIG welding?

A. When MIG welding automotive sheet metal, thin wire is better. Most often . 023 solid wire is used with a 25/75 (argon/CO2) shielding gas.

Can you weld stainless steel with flux core?

If you only want to know the quick and dirty basics so you can weld stainless steel with FCAW, here you go: Buy some 308LFC from Blue Demon and go to town. It’s not overly complicated, and you can probably figure it out with a bit of practice. That will work on the large majority of 300 series stainless and grade 430.

How do you adjust the tension on a flux core?

Grip the wire between your thumb and first finger. Your grip should be firm but not tight (no white knuckles please) Turn the tension adjuster ½ a turn. While gripping the wire as described in 4, press the torch trigger, if the rollers still slip turn the adjuster another ½ turn and repeat.

How do you use a flux core wire feed welder?

5 Tips for Flux Core Welding Beginners

Do you use gas with flux core wire?

Self-shielding flux-cored wire does not require external shielding gas because the weld pool is protected by gas generated when flux from the wire is burned. As a result, self-shielding flux-cored wire is more portable because it does not require an external gas tank.

Do you push or pull when wire feed welding?

Pushing usually produces lower penetration and a wider, flatter bead because the arc force is directed away from the weld puddle. In addition, pushing usually offers a better view and enables you to better direct wire into the joint.

Do you push or pull arc welding?

Push or pull: Here the rule is simple. “If it produces slag, you drag,” says Leisner. In other words, you drag the rod or wire when welding with a stick or flux-core wire welder. Otherwise, you push the wire with metal inert gas (MIG) welding.

What is the strongest welding pattern?

TIG welding produces the strongest type of weld.

What is the weld defects of wire feed speed too high?

Wire feed speed/amperage too high – Setting the wire feed speed or amperage too high (depending on what type of machine you’re using) can cause poor arc starts and lead to an excessively wide weld bead, burn-through and distortion.

What causes bird nesting in welding?

Because welding wire is coiled, it tends to corkscrew its way through the liner as it unspools. If the liner isn’t large enough, it takes more force to push the wire through. This can result in the wire breaking inside the gun or bird-nesting at the feeder.

How do you calculate wire feed speed?

Multiply the required amperage of your weld by the burn rate associated with the diameter of the wire to calculate the feed speed. Using our example, you would multiply the 125 amps by the 2 inch burn rate to calculate a feed speed of 250 inches per minute.
