Just like all welding processes, mig welding has its own complications. Solution: Ensure that the gun liner is the proper size for the wire being used and it should also be cleaned periodically to free it from dust and debris. Increasingly, welding equipment manufacturers are developing MIG welders that simplify parameter settings with automatic features. A bad ground can present itself as a stutter, and cause the wire to perform as if it needs voltage or speed adjustment. In most cases this happens when the machine gets coated with oxides which may alter the flow of current and create high resistance on the machine. Solutions: Replace the cable with the appropriate size stated on the user manual. Solutions: Lateral cracks can be avoided by maintaining a steady welding speed and avoid welding too fast. Cause: If the welding cable gets heated really fast, it could be as a result of incorrect cable size or inappropriate duty cycle.
With a sound knowledge of some troubleshooting skills, you can find the right solution to your welding problems.

A bad ground can destroy a tip with burn-back and spatter. Solution: The remedy for contaminated surface is to clean the material following specified surface preparation procedures. Drive Roll: Drive roll pressure is a very common problem that leads to faulty wire delivery.
Cause: If you notice shrinkage cracks on your weld, the bead may be too small and concave or the wire is rusty.

|Sign Up. Drive Roll: Drive roll pressure is a very common problem that leads to faulty wire delivery. Whether you are running a solid or flux-cored wire, shielded or open arc, even sub-arc, wire-feeding problems are encountered in all of these types of welding. Solution: When work cables are too small or worn out, they tend to overheat.
MIG welding machines often are used as a simple tool for basic welding needs, a relatively inexpensive must-have for every garage.
Solutions to the most common MIG welding problems. MIG welding defects, causes and remedies. MIG (GMAW) and flux-cored (FCAW) welding, commonly referred to. is a welding engineer and curriculum developer for Miller Electric Mfg.

In this process the wire directly touches the weld pool and the end of the wire melts and detaches a droplet as a result of a short circuit in the system. Also, any surface that is open to atmospheric air can be contaminated.

Wire feeding issues can affect performance; good welds require a consistent wire feed supply. All fields are required. If you are using a backing bar, for instance, you should ensure that it is made of the same metal you are welding.
It is a very common welding defect.

Lines and paragraphs break automatically. Normal welding conditions in all positions specify a travel angle of 5 to 15 degrees for good weld puddle control. Many companies post their manuals on-line. Cause: A very common welding defect may be as a result of improper wire feeding which is caused by a worn out drive roller.
