设置正确参数的重要性
It doesn’t matter if you find thebest MIG welder for beginners如果您不知道如何设置MIG焊工。在不学习如何设置MIG焊机焊接的情况下，您最终可能会获得丑陋的最终产品。更糟糕的是，它可能是脆弱的或脆弱的，从而降低了完整性和力量。我们将帮助您找到任何项目的最佳MIG焊机设置。
MIG Welder Setup Considerations
What type of metal & thickness will I be welding?
To learn how to set up a MIG welder with gas, you must first examine the metal you are using. Each type of metal alters the machine settings, gases used and electrodes needed. That's because each material has a different melting point. Additionally, it would be best if you considered the thickness of your material.
我将如何准备关节？
Even if you know how to set up a MIG welder for stainless steel, your work will mean nothing if you don't prepare the joint properly. You must remove all of the oils, rust, dirt, paint, and other contaminants from the surface. Otherwise, you won't get a clean weld, and the setting might not provide an effective weld.
Do I have the right gas and electrode/filler wire?
除非您想学习如何设置无气Mig焊机，否则需要选择合适的屏蔽气体和电极。碳钢倾向于使用ER70S电极，加上C25气体（氩气和二氧化碳）。不锈钢焊接通常需要带有C2气体（氩气和二氧化碳）的ER308L，而您希望使用铝和纯氩气的ER4043。
Important Parameters When Welding
Welding current
The welding current is the amount of electricity jumping across the arc gap between the metal and your electrode. This electric current is just a flow of electrons that can be adjusted to produce more heat and temperature.
焊接电压
When welding with yourMIG welder, you will almost always use DC power. With this voltage setting, the electricity is flowing from the metal to the welding handle, making the handle the positive end of the circuit. To change this setting, which you wouldn’t want to do, you would unbolt the internal leads and flip them. Simply put, the MIG machine isn’t designed to go the other way.
Wire electrode extension
The wire stickout is how long the unmelted wire extends past the contact tip end. This variable is essential because it controls how much resistance the electrode wire has before it ends up melted into the weld pool.
Arc travel speed
弧线行进速度突出了弧线在工件上移动的速度。此设置通常表示为每分钟或米。如果您没有正确的套件，则焊缝看起来可能不好或不像必要的那样坚固。
如何设置MIG焊工（最重要的考虑因素）
How to Set the Welding Current
Your material thickness determines the amperage you need. For example, you will need a different setting when learning how to set up a MIG welder for mild steel versus how to set up a MIG welder to weld aluminum. As a general rule of thumb, figure one amp of output for every 0.001-inch of thickness. For example, if you are working with 0.125-inch thick material, you will need 125 amps. You also need to choose the right wire size based on amperage. Here’s a handy guide as you learn how to set up a Lincoln 180 MIG welder.
How to Set the Welding Voltage on a MIG welder
直流电压是使用MIG机器焊接时唯一的选择。您的电压决定了发生多少渗透率，因此您想使用焊工提供的手册。如果没有图表或手册，则可以在焊接时调整电压，以确定弧线何时在工件中固定。调整电压水平，直到弧杂有组织和草率。
How to Set the Gas for MIG Welding
Unless you are learning how to set up a MIG welder without gas, this is an important step. Your gas flow rate setting regulates the gas transfer to protect your welding area from contaminants. The lower setting allows less gas out, which could result in porosity. Going higher might result in extra turbulence that can also lead to contamination. You will probably need to run some trial and error on scrap metal to find the right settings for your project.
How to Set the Wire Feed Speed
电线饲料设置确定电线被馈入接头的速度。您会发现设置是每分钟或IPM进行的。如果您的速度太高，它可能会造成燃烧，但是当它太慢时，它会产生不稳定的弧线。总体而言，您可以将电线送入焊接接头的速度越快，接触越好。
People Also Ask (FAQs)
您是否需要汽油进行MIG焊接？
To weld without gas, you need a special type of welder. However, it’s not difficult to learn how to set up a MIG welder for flux core.
您用于MIG焊接哪种气体？
Just like when using a提格焊机, you will use a mixture of gases to MIG weld. Your gas options include carbon dioxide, argon, oxygen, and nitrogen.
How do you adjust a welding regulator?
Turn the valve’s tank counterclockwise slightly to open it. Adjust the regulator until the gauge begins to register. You also want to open the torch valve on the handle until it stops moving.
MIG焊接时会推还是拉力？
这取决于您正在从事的工作。当您推焊缝时，您会看到要去的地方，而当您拉动时，您会观看来自哪里。拉动使您有机会在创建时看到珠子，这是许多焊工更喜欢的。
GMAW MIG焊接需要什么电源？
You will want a constant voltage, direct current power source with GMAW.
Where can I find a MIG welder setting chart?
最好查看您拥有的模型的制造商网站，以获得最佳结果。
Conclusion
Even if you purchase a便宜的米格焊机, you can produce a solid product, as long as you use the appropriate settings. Take time to acclimate yourself with the right settings and practice until you get it right.
