Mar 29, 2019· Use the proper gas ratio. Depending on if you are using TIG (tungsten inert gas) or MIG (metal inert gas), and the thickness of your copper, you will need to adjust the ratio of your gas and temperature. As a general rule of thu, copper under 2 mm should have argon gas and up to 160 A applied. If the copper is thicker, you will need to adjust the gas and amp by applying helium and …

Feb 04, 2018· “For better penetration, keep the arc at the leading edge of the weld puddle,” says Collier. The exception to this rule would be when welding thin sheet metal. In this case, keep the arc back farther in the puddle to prevent burn-through. 7. Match Drive Rolls, Gun Cable Liner, Contact Tip to the Wire Size
For example, if the base material being welded is 6061 aluminum, good filler metal options include 4043, 4943, and 5356. A 4043/4943 gas metal arc welding (GMAW) wire or gas tungsten arc welding rod can reduce porosity and provide better weldability and increased puddle fluidity, while a 5356 product provides greater toughness and strength.

May 12, 2009· It may be possible to rig a low power spot welder, perhaps from a deep discharge 12 volt battery or a heavy capacitor, but controlling the size of the arc to avoid burn out might involve looking at computer assely circuits (i.e. specialized) [And if you are using galvanized wire, you risk lung damage from the burned zinc coating if you don''t
Looking at the wire capacity row, 10 AWG is the smallest gauge wire that can safety be used. It is rated at 30 amps, higher than the required 25 amps. Next, we look at the Array amps column, select row “25” and you can see that a 10 AWG wire pair only supports a cable length of 4.5 feet!
Jun 10, 2009· There is a chapter in the Lincoln Electric book titled ''The Procedure Handbook of Arc Welding'' that goes into all this. It says deposition efficiency is typically in the 65-70% range. It also has a big table showing weight of weld metal in pounds per foot of joint. It shows depth of weld, weld gap, and various cross sections of the weld to pick

A JB Weld review shows that it can withstand temperatures up to 500 degrees Fahrenheit. However, it is not recommended on car exhausts, mufflers or converter systems in the exhaust area. Once dried and cured, it only can be removed by exposure to heat above 600 degrees Fahrenheit, sanding or filing off from the places it was applied.
With TIG welding the filler wire is always added to the joint with the opposite hand, which gives you full control over the deposit rate and weld size. The electrodes have a coding system to identify them. A commonly used electrode for mild steel is “ER 70S-2” “ER” stands for electrode or filler rod. “70” is the strength of the weld
