If you are working with the Yeswelder MIG Pro 250, you will have to consider factors such as the diameter of the wire and the type of metal.
For instance, if your project involves a stainless steel wire with 1.2mm thickness, then you should aim for a voltage of 21- 22 A, amperage of 110 – 130 A, and speed of at least 120 IPM. But for an aluminum wire of 3.2 thickness, then you should use at least 21V and 110V while the speed stays at 350 IPM
How Do I Change the Wire Speed on the Yeswelder?
If you want to set the wire speed on the Yeswelder 250, use the following steps:
- Press the arrow button on the welder to highlight the enter the speed setting
- Tune the knob to set the speed to your desired value
What Voltage Should My MIG Welder Be Set On?
The voltage of your MIG welder depends on the thickness of the metal for your project. Let’s say you are working with 4.8mm aluminum, then you should set the device to 23 – 24 volts. But as for 9.5mm steel, then the voltage should fall between 26 – 28V.
At What Amp Should I Weld?
If you are using the Yeswelder 250, make sure the amp suits the thickness of the welded material. For instance, aluminum with 11.1mm thickness requires 280A while steel of the same size works with an amperage of 275 – 300A.
What Happens if Your Wire Speed is Set Too Low?
If your wire speed is set too low, then your welding will have several issues. These problems include weak penetration and wide weld beads. As for thinner materials, the welded metal might end up with signs of burn-through.
What Happens If a Voltage is Too High in Welding?
If you use high voltage with your welder, there is a high chance that the metal might have an undercut. Besides, this defect reduces the quality of the weld.
What Are Some Common Mistakes to Avoid When Welding?
As you weld, avoid the following errors as they can affect the quality of your work:
Working with Dirty Metals: Using greasy metals for your project comes as one of the welding mistakes that you might make. By using such items, your result will be weaker than expected.
Using the Wrong Settings: If your settings are wrong, you might end up with a messy or weak weld. But if you use a guide, you can avoid these problems with your project.
