# How do you calculate wire feed for a MIG welder?

## How do you calculate wire feed for a MIG welder?

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.

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 when you weld too fast?

Move too quickly, and the arc may not have enough time to adequately melt the base material, leading to a thin, narrow weld with poor fusion and penetration.

### Is Stick welding stronger than MIG?

When done correctly, stick welding produces stronger joins than MIG welding.

How fast should you move when MIG welding?

There are many variables here, but a good rule of thumb for light-duty welding is to use about 20 cubic feet per hour of gas flow. Once you’ve developed some skill with the gun, you can experiment with optimizing the amount of gas used.

How thick can MIG weld?

1/2-inch thick
The MIG process enables the home-hobbyist, artist, farmer/rancher, motorsports enthusiast or DIY welder to make most types of fabrication and maintenance/repair welds on material from 24-gauge up to 1/2-inch thick.

## How dangerous is MIG welding?

– During welding, many dust particles produced. Those are very small in size, and they emerged like smoke and creating inhalation problems. – The fusion of metals during welding gives rise to many toxic gases. Argon, Ozone, Carbon dioxide, nitrogen, and nitrogen oxide included. – Under the above discussion, we try to understand: how dangerous is welding?

Which is better, arc welding or MIG welding?

MIG welds are known to be more pleasing to the eye and would not require a lot of touch-ups. This will be highly different from arc welds that will require a lot of cleanups before they can look presentable. Arc welding will usually have a lot more sparks and debris which can make the welds not very appealing.

How to select a MIG welder?

What kind of welding do you have in mind?

• Could you imagine that in 6-12 months you will be doing other projects?
• Do you have the patience,desire and ability to learn a complicated welding process?
• Are you looking for a quick and easy welding technique?
• What price range can you afford?
• Do you plan to weld only in the garage or will you work outdoors?
• ### How to choose a MIG welder?

– Easiest process to learn – High welding speeds possible – Better control on thinner metals – Cleans welds possible with no slag to clean – Same equipment can be used for flux-cored welding
