What can occur if a welding machine has loose cable connections?

No. Check for bad ground connections and loose or damaged cables, which can lead to excessive spatter. Damaged cables can also cause drops in voltage and lower heat input, resulting in inconsistent weld quality.

Why is my wire welder popping?

The wire is hitting the surface and not melting into the metal fully. You will feel the wire pushing back on the MIG gun because of this, and you will hear a lot of random popping from the welder. When you do this you will notice a pronounced “hissing” when welding. This will sound like you have a gas leak.

Why is my welder spitting and sputtering?

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 does my MIG welder stop feeding wire?

The wire can also fail to feed if the trigger switch is broken, or control leads in the gun cable are damaged. If this is the case, they will need to be replaced. If the drive rolls are turning but the wire is not feeding, it is usually caused by inadequate drive roll pressure or a blockage in the contact tip or liner.

Why does my MIG welder keeps jamming?

If the Mig Welder Wire Feed Roller Tension is too great on softer Mig Wires (e.g. Flux Cored & Aluminium), the wire can be slightly flattened, so instead of your welding wire being, say 1.0mm in diameter, it may become 1.1 x 0.9mm, this will then increase the risk of jamming at the copper Tip.

Does welding wire go bad?

Flux core wire is commonly used in welding, and it is vital to know if it can go bad and how to know if it’s no longer viable. Does flux core wire go bad? Flux core wire is not solid, so contaminants such as moisture can enter the wire. So, if flux core wires are exposed to moisture for a long time, they will go bad.

Does welding wire have a shelf life?

Do welding electrodes have a shelf life or do rods go bad? Yes, welding rods can go bad depending on the model of rod that is used and the conditions they are kept in. Welding rods hold a shelf life around 2-3 years in ideal conditions.

Why does my Weld look like popcorn?

A weld may look like popcorn when the wire is speeding too fast or slow or when the fire feeding happens before the melting. If you use solid wire without shielding gas, you might also hear popping sounds. Other reasons may include the wire’s incorrect size, amperage adjustments and voltage.

Why is my MIG welding splattering?

MIG Settings A common cause of MIG welding spatter is excessive speed or irregularity with your wire feed. Spatter occurs when the filler wire enters the weld pool. It can also create a sticky nozzle tip when the wire melts near it. Residue builds up, causing an inconsistent feed rate due to the wire sticking.

Why are my welds splattering?

MIG Settings A common cause of MIG welding spatter is excessive speed or irregularity with your wire feed. Spatter occurs when the filler wire enters the weld pool. The solid wire melts at a rapid rate due to the extreme heat. As it melts, the filler wire turns into a liquid form, creating the pool.

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 happens if you over tighten the wire on a welder?

This should be just tight enough to keep the wire from de-coiling when you stop feeding a full spool at maximum wire feed speed. Over-tightening this will force the drive motor to work harder just to get the wire off of the spool and will lead to welding problems.

Why is it important to troubleshoot welding wire delivery problems?

Accurately troubleshooting problems with the delivery of the welding wire to the weld pool and the current to the wire when they arise or, better yet, avoiding them before they arise, is crucial to maximizing the benefits that these processes offer.

How do you check the tension on a cold feed welder?

To check tension, disconnect the welding input cable from the feeder or switch to the cold feed option. Feed the wire and pinch it as it exits the gun with the thumb and forefinger. If the wire can be stopped by pinching, more drive roll tension is needed.

What are the most common problems with a welding pool?

Fusion problems may occur when the metal in the weld pool is melted, but there is not enough energy left to fuse it to the base plate. In these cases, the weld will have a good appearance, but none of the metal has actually been joined together.
