8 Tips for best results from MIG welding

MIG welding is a versatile technique that can be used for both thin sheet and thick section components. MIG welding is surely not a simple technique but you can become proficient in this by following these useful tips that will help you sharpen your MIG welding operations and improve the quality and precision of your welds.

Clean the surface

Porosity is the major reason for MIG weld failure which is usually the result of welding a surface that is oily, dirty, or painted. All these pollutants get trapped into the weld and result in holes that look like a sponge.

Ground should be good

Welding arc needs a smooth flow of electricity through a complete electrical circuit. Even, if it is a bad ground, your welder doesn't care; he keeps on taking welding wire anyway without worrying that the gun is sputtering and stuttering.

So, it needs a smooth welding ground that is close to the arc so that the current doesn't find any other pathway.

Keep the stickout short

The distance between the wire sticks out to the end of the gun’s contact tip must be 1/4 and 3∕8 inch. This simple tip can have a big effect on your welds.

Use your both hands to make welds

You can rest the crook of the gun neck in one hand while holding the gun's trigger in another hand. Use a heavy quality welding glove that is heat resistant, so that you don’t hesitate in having your hand close to the weld and getting it done more precisely.

Listen to your MIG welder

Sounds indicate a lot while welding. A steady hiss indicates your voltage setting is too high. A loud and rough sound indicates the voltage is too low. A crackling sound like a machine gun going off indicates that the amperage setting is too high.

Keep the arc up front

Keep the arc at the leading edge of the weld puddle, for better penetration. But for welding thin metal sheet, the rule is different. For this, keep the arc farther to prevent any burn.

Push or pull

Pushing the gun towards the direction of the weld is known as the forehand method and it creates a shallow penetration. Dragging the gun towards the weld is known as the backhand method and it creates a deep penetration.

You can use these methods depending on the thickness of the metal you want to weld and how deeply you want to weld.

Replace the contact tips often

Worn out tips need to be replaced immediately as they tend to lead to an erratic arc. They are cheap and replace them often for ensuring high-quality welding.
