  • 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.

  • 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...
  • Wiring and Fabricating a Fuse Box Mount

    One of the biggest hurdles of converting Project Pile House from “garage art” to an actual running, driving vehicle is putting some wiring into the vehicle. I’m running a carbureted small block Cheverolet V8 (SBC) so there is little to make the truck run and move under its own power, but some wiring is needed to make it street legal.   Click Here To Read Full Post...
  • Welding Supplies- Items Every Welder Needs

    Whether you’re a seasoned pro or just starting out in the field of welding and fabricating, there are a few essential tools and supplies that you’ll need commonly. We decided to survey a group of welders (all of different skill levels) and see what welding supplies they commonly reach for when melting metal.  Click Here To Read Full Post...
  • Building Custom Mini Wheel Tubs for Pile House

    One thing a lot of longterm builds have in common is that the builder or owner tend to change their minds throughout the build. This has definitely been the case with Project Pile House. Over the past two years I've changed Pile House from being a "thrown-together" type build to something a bit more thought out and nicer. Even small items like wheel and tire combo have changed and caused me to go back and adjust things as needed.  Click Here To Read Full Post...
