When an arc welder is a bit too much for you because you don't have a lot of welding experience, a stud welder is the perfect alternative. With an easy to use formation and a welding process that only requires you to hold the stud welding gun, it is much easier to get accustomed to using a stud welder than any other type of welder for most people. Here are a few of the more common questions about stud welding systems. 

How do you know the appropriate plunge length to start with when you weld?

Even though your welding gun may have set recommendations for plunge, or the length of the welding stud that protrudes beyond the tip of the gun, it can take a little trial and error to get the length just right. Different metal materials will react differently to the welding material. Therefore, some metals will immediately require more length than others. The easiest way to get accustomed to setting the right plunge length is to try your hand at welding a few varying materials. A good guideline to follow for just starting out will usually be included in your stud welder owner's manual, but in a lot of cases, the length of the stud extrusion should be about 1/8 of an inch or less. Use this as a starting point and then work to develop your own conclusions with various materials. 

What does a good weld look like?

Once you have set the weld stud in place, you may initially have a difficult time telling whether what you have just accomplished is good enough. It takes a good welder a while to be able to recognize the difference between a good and bad weld. However, a few characteristics of a good weld will include:

  • a clean and even fillet all the way around the base stud
  • no concaves that indicate overheating at particular points
  • no welding material spatter beyond the actual welded area
  • no stringers or spider legs radiating from the weld

What is the easiest way to measure the lift of the stud welder?

An easy way to define the lift of a stud welder is a measurement of how far the stud gun will raise the load stud above the base plate. The easiest way to measure lift is to turn the gun on, press the trigger, and then measure the distance that the stud moves outward.
