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.

So you decided to give your car a refreshing new look and it's time to strip it down to prepare the car for paint. You can count on finding some sort of surprise when tearing the vehicle down. Whether it's hidden accident damage, previous repairs, or the mummy of a dead animal; it's always an adventure when stripping a car or truck down for paint or bodywork.
I recently started tearing into my "clean" (for the east coast at least!) 1977 VW Scirocco I've owned for a few years. It had some wear and tear and some bubbling paint I wanted to address before it got a fresh lick of paint. When I began removing the fenders I was pretty surprised to find some rot in the inner fender and windshield cowl. I decided to take some photos as I repaired this area and share some tips for making a repair that will look original when done.
Here is the offending area when I removed the fender. The worst rot was in an area that sandwiched between the fender and cowl and was covered with weather stripping. So from first glance it just looked like some bubbled paint, but that was the tip of the iceberg.
I first cut out the area that was rotted until I got to solid metal and a nice seam where I could weld and blend the panel into the original metal.
I started making my patch panel by bending up a piece of construction paper to the rough size I needed, then I transferred the rough shape over and cut it out of 20 gauge aluminized steel. Next I measured the other side and marked out the bend line I needed to make.
In order to make a clean bend in the new metal I needed a metal brake. I decided to use the Versa Bend Sheet Metal Brake and put a crisp 90 degree bend in the panel on my line.
With the patch panel now formed into the rough size I needed, I took it to the car and trimmed it to fit the opening. It's here that you want to make sure the patch panel fits tightly so that you don't need any excessive welding to fill voids.
I then setup the MIG 135 with .023 Solid Core MIG Wire so I could lay small, flat spot welds on the patch panel. Setting the machine up on a similar piece of scrap metal helped me get my spot welds laying flat and penetrating correctly. After finessing the panel with Eastwood Hammers and Dollies and blending the welds with a flap disc on an angle grinder I was satisfied with the repair. I'm happy to say the patch panel looks close to original and the repair should be invisible once it has primer and a top coat on it. Now onto the next surprise!Click Here To Read Full Post...
In one of our last posts we gave you some sneak peaks of the custom running board project we've been working on for Project Pilehouse. During the process we documented the full build and shared some of our secrets to help you build a similar project yourself for cheap. After a some editing, we have the video chopped down and ready for your viewing. Check out the DIY video below and see some of our great Eastwood tools in action!Click Here To Read Full Post...
PileHouse is starting to shape up and we can now envision what the truck will someday look like when it's "done". But I still felt that the front end needed "something more". After staring at it over lunch one day, I decided that the truck needed a custom bumper to "complete" the front end. My only rules were that it had to flow with the grill trim and relatively flat front end. So I took some measurements, snapped a few reference pictures with my Iphone, and headed off to one of my favorite places; the New Ringgold U-Pull-It junkyard. This place is HUGE and they're nice enough to drop all of the "classic" cars and trucks in one section where you can rummage around. It's there you'll find everything from a 40's Ford to an El Camino or even obscure European classics like a Renault LeCar. This place is a hotrodders dream! All you need is a battery powered reciprocating saw, some hand tools, a tape measure, and a good imagination to find parts for your custom project.
So I set off with my bag filled with Eastwood Hand Tools and the portable reciprocating saw in hand. After a couple hours measuring bumpers, and scratching our heads, my buddy Matt R. and I narrowed it down to two vehicles. Eventually we chose the front bumper off a 60's Chevy Corvair van (obscure enough for you?!). The length and shape was pretty darn close to the stainless grill trim on PileHouse, and I was sure I could make it work. We quickly got down to business and cut the bumper off so I could bring it home.
With bumper and truck meeting for the first time, I can see that although the size was "close", the bumper was still going to need a few inches chopped off, and the radius changed to match the front of the truck.
I started by marking the corners of the bumper where I wanted them to sit and noted some measurements of the bumper and the front end while on the truck to give me some reference points throughout the project. Next I pulled out the angle grinder and cut the bumper in half in the center, and laid it back in place.
After test fitting the bumper halves, I overlapped them in the center to give me an idea of what had to be removed to get the bumper to the correct length. Once I cut the excess off I found an additional cut had to be made to allow the bumper halves to lay back to match the curve of the front end. With this last cut made, they were sitting exactly how I wanted and I spot welded them in place until I could join them together. Finally, I welded some small strips of metal in place to join the halves temporarily.
With the bumper now shaped to fit the front end of PileHouse, I removed the tack welds on the corners and put the bumper on the work bench to add braces to the backside and ground off the temporary front braces. Next I had to fill the opening that was created when the radius was changed. I found that the last piece I cut off was a good fit after a little sanding. With the filler metal set in place, I began welding it all together with the Eastwood MIG 175. After welding the seams up on both sides I took the angle grinder with a flap disc and blended the welds. A few minutes of grinding I had a smooth, invisible transition where I had modified the bumper.
With a complete front bumper bar, I test fit it one more time. I'm happy to report I now have a bumper that fits perfectly and I'm only out about $30 and a few hours of work! From here I'll fabricate some simple bumper mounts to bolt it to the chassis, and then we can move on to the next step in making PileHouse road worthy!
