Made by one of the leading manufacturers in the industry, the Goldsource STU series step up/down voltage transformers offer you a safe, reliable, affordable & convenient solution to converting voltages from 110-120 volts up to 220-240 volts or from 220-240 volts down to 110-120 volts for both home use & industrial applications.

The STU-1000 is rated at 1,000 watts maximum. It features a heavy-duty cord with a standard US 3-prong plug plus a free American to German outlet plug adapter. There are a total of three outputs on the front panel. Two are grounded outputs, one designated for 120 volts with a US standard outlet, the other for 220 volts only with a universal outlet. The last one is a 5V standard USB jack, a unique feature of the STU series & 1st in the industry. And most importantly, all three outputs can be used simultaneously & continuously.

For safety, it's recommended by the manufacturer that the voltage transformer's maximum power should be equal or greater than the power rating of your appliance multiplied by 1.5. For example, if you have an appliance rated at 100 watts, you will need to pick a transformer with a maximum power of 150 watts or greater.

How to Weld With a Wire Feed Welder

!±8± How to Weld With a Wire Feed Welder

How do you weld with a wire welder?

Man, that's a loaded question. Why? because there are so many applications where a Mig welder is used.

First off, lets gets some terminology cleared up. The AWS (American Welding Society) would appreciate it if we all called it Gas Metal Arc Welding. They have been working on that for over 20 years... Even though about 90% of all welders still call it "MIG". They just wont give up.

I call it MIG too. But some people just call it "wire welding".

It doesn't matter what you call it, its the same thing. So let me give you a few tips on how to weld with a wire welder.

Lets start off with the little 115 volt wire welders. They are the best thing since sliced bread for auto body panels and thin sheet metal. The Hobart Handler 140 is a good machine for welding auto body panels because it comes with a gas conversion kit.and will run small .023" wire.

You need .023" bare E70S6 wire, 75/25 Argon CO2 gas, and a steady hand. Always weld thin sheet metal downhill when you can, and in short runs with an air nozzle handy to cool each half inch bead before you start the next one.

For trailers and trailer hitches, ditch the 115 volt mig welder and step up to a 230 volt mig welder.

The Hobart Handler 187 is a good choice. It will run .023" wire for thin sheet metal, but also will go up to 185 amps and use .035" bare wire or flux core for thicker metal where penetration is critical. You still need 75/25 gas and some E70S6 bare wire. But you can use .023" bare wire for thinner steel and .035" bare wire for higher amperages.

So how do you weld with these wire welders? Here is the rundown...

Make sure the machine leads are hooked up with the electrode positive. Set flowmeter gas flow to about 20-25 cfh Use the right size drive rollers to match the wire you are using Make sure the contact tip is flush with the nozzle Set Voltage and wire feed speed using the chart that comes with the machine you are using. Hold the torch close to the work so that there is only about 1/2" of wire sticking out from the contact tip to the weld. Dont get carried away with torch angle...5-10 degrees works in either direction for most applications. Practice on scrap before you weld the real deal. If the weld you are making is critical, do some destructive tests with a hammer on a mock up weld first. get an auto darkening welding helmet so you know exactly where to light up
