With so many complicated factors to consider- right equipment, welding
technique, filler metals, and consumables- mistakes will inevitably occur in
most welding operations. As beginners, new MIG welders are meant to make
mistakes. However, making mistakes and then getting away from it just by saying
sorry doesn’t always work. You need to look for alternative ways to improve MIG welders’ performance and learn how to prevent them. We have listed the most straightforward
guide with a list of mistakes that you need to avoid.
Mistake #1. Improper voltage
Many welders make this mistake often. They set the wrong voltage or
wrong wired feed speed while welding the metal which caused an erratic arc in
the metal. They don’t possess the knowledge when current to use AC or DC while
using metal. Being a MIG welder, you need to know which flow of current to be
used.
Mistake #2. Choosing the wrong size MIG gun
MIG gun also plays a major role in driving quality welding results.
However, using a too-low or too-high amp MIG gun can unnecessarily exert an
unavoidable effect on the output. Welding metal isn’t a whole day task and
that‘s why using a lower amperage MIG gun or one with a lesser duty cycle on
some applications consider the best option. Be mindful of the requirement of
the welding project and select a MIG gun with enough duty cycle and average
capacity.
Mistake #3. Overheating of consumables
Using an overheated MIG gun’s consumables can be the primary source of
many problems. To prevent the best MIG welder gun from overheating, use the wire stick out, use a low amp duty cycle and
set the right contact distance. Any steps that keep MIG consumables cooler will
help limit the amount of vibration in the gun and reduce further issues.
Mistake #4. Selecting the wrong drive roll
Using the wrong drive roll type or set inaccurate drive roll tension can
also cause an erratic weld arc. Before setting or using the drive roll, first
consider the size and type of wire that need to be used and then match it to
the correct drive roll. Without accurate drive roll tension, erratic feeding of
fire can cause burn back or other issues.
Mistake #5. Ignoring preventive measures
Preventive measure is a frequently overlooked part of the welding
operation. It is very complicated to prevent the unscheduled downtime and
keeping repair costs low. A well-performed preventive measure can help to
increase the best MIG welder productivity and extend the welding device life.
For this, welders need to develop a regular timetable to inspect their power
sources, MIG gun, and wired feeders during scheduled downtime in production.
Avoiding common MIG welding mistakes can help you get the best results.
It is just as important as maintaining the condition of MIG Gun and consumables
intact. MIG welding is one of the most natural techniques of welding for
beginners. Having the proper knowledge on avoiding pitfalls and hands over the
right MIG device can help you get the most accurate welding results.
