  • MIG Welding Duty Cycles

    When you are using an arc welding machine, you will need to understand what its duty cycle is as it will help you preserve the life and quality of your tool. On this page, you will learn about what a duty cycle is and how it is relevant to MIG welders, specifically.

    The MIG Welding Duty Cycle

    When you purchase a MIG welder, you will notice a specification on the packaging or in the manual called the duty cycle. This refers to the amount of welding that can be achieved in a given amount of time. The reason this specification is important is it informs the user of how long the MIG welder can work at its optimum level, since MIG welders, or any other welders, do not perform continuously as opposed to some other automotive tools that do.

    A perfect example of a duty cycle can be found in the Eastwood MIG 175 Amp Welder. The MIG 175 has a rated duty cycle of 30% at 130 amps. This means that the power signal of the MIG 175 should remain on for 30% of the time and off 70% of the time at 130 amps of power. If you look at your welding time in increments of 10 minutes, the duty cycle is a percentage of that 10 minute increment. In other words, with a 30% duty cycle at 130 amps, you can weld for three solid minutes and should let the welder cool off for seven minutes. You can increase the duty cycle percentage by turning down the amperage output, but going above the amp output (in this case, 130 amps) will yield a lower duty cycle. If you exceed the duty cycle and the breaker is tripped, allow the MIG welder to cool down for at least 15 minutes. A rated duty cycle on any MIG welding machine is there to protect you and your welder from any long-lasting damage.

  • Project Pile House- Custom Hidden Hood Hinge Project

    The next part of the project was making the hood open on custom hinges. I was hoping I could find a pre-made hinge kit that allowed me to open the hood from the front like most cars currently have. Unfortunately all I found were kits for wild customs and street rods that opened from the back and tilted forward or to the side. As much as I like custom touches, making my vehicle look like a transformer is not one of the things I want to do this time around. I decided to take a crack at making my own hinges that disappeared behind the dash and share the process.   Click Here To Read Full Post...
  • What is a Lap Joint and How Do You Perform One?

    A common joint found in auto repair work, the lap joint is a piece where two pieces of metal overlap each other. An ideal lap weld should have a good amount of weld bead penetration without the upper edge melting back or overlaying. If the upper layer melts too much, the lap joint will be too weak and thin. Making lap welds takes a good amount of practice to get it right, so experiment with your welding angle, arc length and rate of stitching welder travel to find the best combination for you.  Click Here To Read Full Post...
  • How Can I Control Warping While MIG Welding?

    Sometimes, if you are welding two pieces of metal together, you might experience a warping of the metal surfaces. Warping can occur either if your material preparation is not performed correctly or if you make certain errors while welding. The three main ways you can warp metal materials when welding are: a lack of tack welds, the materials are not clamped together while welding, and if you have a poor welding technique. Below are various ways you can remedy these issues.  Click Here To Read Full Post...
  • Project Pile House Shaving and customizing the original dash and glovebox.

    While I had the column out I decided to start cleaning up the dash and sort out my brake pedal dilemma on the truck. In order to get under the dash for fabricating the new brake pedal setup and to shave and smooth the dash I needed to pull it out. ....  Click Here To Read Full Post...
