What metal thicknesses can the ANDELI MIG Welder 135Amp flux MIG process weld?

The ANDELI MIG Welder 135Amp can weld mild steel plates up to 2/5 inch thick. This capability is determined by the 135A output current and the specific flux core wire compatibility of the unit.

The 135A output current is the primary factor for penetration, allowing the machine to fuse metal rather than just creating a surface bead. For the 2/5 inch maximum thickness, users should verify the specific heat requirements in the manual to ensure the duty cycle allows for continuous welding without triggering the overheat protection. Because this is a gasless MIG welder—a machine that uses a spool of wire and a powder coating to create a weld without external gas tanks—the wire diameter is critical. The unit supports .030 and .035 flux core wire; generally, the .035 wire provides better stability for the thicker end of the 2/5 inch range. We selected this unit for our comparison because it offers a dual-voltage 110V/220V setup for portable use. To avoid “stubbing” the wire or burning through thinner gauges, you must adjust the wire feed speed precisely, as the machine lacks a dedicated gas flow setting since it is designed for gasless operation.

What to Check Before Buying the ANDELI MIG Welder

Because welding thick metal requires consistent heat and stable arcs, verify these technical points before purchase:

• Confirm if your specific project requires 135A of power to achieve full penetration on 2/5 inch plate, as lower amperage may only produce a tack weld.
• Check the manufacturer’s support page for the recommended wire feed speed for .030 vs .035 wire to prevent wire feed jams.
• Verify the ground clamp cable length provided in the package to ensure it can reach your workpiece for a stable arc.
• Review the manual for the specific duty cycle limits when welding at the 135A maximum to avoid mid-job shutdowns.
• Ensure your workspace allows for the compact footprint of the IGBT inverter technology.

Comparing the ANDELI MIG Welder to Other Options

The ANDELI MIG Welder sits in the entry-level category for hobbyists who prioritize portability and a gasless setup. If you need to weld heavy industrial plates consistently or require high-volume production, you may need to look at higher-amperage machines that exceed the 135A threshold. This machine is ideal for home repairs and small fabrication projects where the ability to weld without a gas cylinder is a priority. Users requiring professional-grade penetration on heavy structural steel may find the 135A limit restrictive and should seek out industrial-grade multi-process welders instead.

If you are a hobbyist looking for a portable, gasless welding solution for light fabrication and mild steel repairs up to 2/5 inch, the ANDELI MIG Welder is a suitable choice.
