Gasless MIG Welding Settings Chart and Guide

If you are working on mild steel, gasless welding should be your preferred option. Unlike gas welding, this method can be used outdoors without any fear of contamination. But before you can get the perfect gas weld, you should set your welder with your ideal settings.

Now the question comes — should your gasless welding project use the same settings as gas welding? Well, the answer is NO. After all, both methods use different materials and even polarities. 

Would you like to start gasless welding? If yes, then you can use the following guide to improve the quality of your work. 

Gasless MIG Welding Settings Chart and Guide

Here is a chart showing MIG settings for gasless welding. Although these parameters are well-researched, it would help if you tested them on scrap metal before using them with your project. Besides, use these settings with steel and set the polarity to DCEN

If you are working with a .030″ 18 gauge wire, then you should use 14 volts while the wire feed speed stays at 125ipm. But if the same wire has a 0.045 thickness, then the volt/wire feed setting stays at 1V and 15 ipm.

If your gasless project involves 16 gauge wire with 0.030″ thickness, then you should use 4V and 20 ipm. But for ⅛” wire with the same thickness, the voltage stays at 7V and 40 ipm. 

How Do You Set Up a Gasless MIG Welder?

Here are the general steps for setting gasless MIG welders 

• Connect the welder to a power source
• Put the earth clamp into the positive socket
• Put the polarity cable into the negative socket
• Insert the roller into the machine
• Remove the spool holder nut from the machine
• Place the spool of wire into the spool holder
• Screw back the spool holder nut 
• Pass the wire over the driver roller and into the inlet drive tube
• Lock down the top pressure roller
• Use the tension adjustment knob to apply minimal pressure
• Hold the torch and remove the nozzle and contact tip
• Squeeze the trigger on the torch to feed the wire out of the nozzle
• Screw back the correct tip over the wire
• Replace the gas nozzle to the torch
• Cut out the excess wire from the nozzle
• Press the arrow button on the welder to choose your  preferred wire size
• Turn the Power knob to choose for welding wire thickness
• Use the earth clamp to hold the workpiece

Which Metal Cannot Be MIG Welded?

Although MIG welding is a great option for welding some metals together. Such combos include titanium and steel or copper and aluminum.
