What materials can be joined using the ANDELI 135A 4-in-1 MIG Welder?

The ANDELI 135A 4-in-1 MIG Welder can join carbon steel, stainless steel, and thick steel, but it is limited to a maximum thickness of 5.0 mm (0.19″). Because this machine is designed as a versatile multi-process welder—a tool that can switch between different welding styles like MIG and Stick—it allows you to work on various metals without always needing a dedicated machine for each.

The ANDELI 135A supports flux-cored MIG, gasless MIG, lift TIG, and MMA (Stick) welding. For the metals it can join, you can use flux-core wire, which eliminates the need for external shielding gas tanks and regulators. This is a vital consideration for MIG welding because many hobbyists prefer a gasless setup to avoid the cost and complexity of gas management. We selected this model for our comparison because it includes an adjustable Hot Start and Arc Force function to improve weld quality on different materials. The machine is compatible with .030″, .035″, and .040″ flux-core wire. If you need to weld materials beyond 5.0 mm or require specific polarity settings for non-ferrous metals like aluminum, you should consult the manufacturer’s support page as the provided facts do not confirm aluminum compatibility or specific polarity switching for varied alloys.

What to Check Before Buying the ANDELI 135A

Before purchasing, verify these technical requirements to ensure the welder meets your specific project needs.

• Confirm that your project pieces are under 5.0 mm (0.19″) thick, as the machine may struggle to penetrate heavier plates.
• Verify if you need a dedicated Stick mode for specific metals, as the MMA function on this 4-in-1 unit handles materials that MIG cannot.
• Check the internal liner compatibility for your specific wire brand to ensure the .030″ to .040″ wire feeds without jamming.
• Verify the duty cycle limits in the manual to ensure the machine won’t shut down during long, continuous welds on thick steel.
• Ensure you have the Lift TIG torch ready, as the 4-in-1 functionality requires this component to be purchased separately.

Comparing the ANDELI 135A to Other Welders

The ANDELI 135A sits in a category of multi-process machines that prioritize versatility over high-amperage output. If you are a hobbyist who needs to switch between different welding styles—like using Stick welding for heavy repairs and flux-core MIG for general fabrication—this 4-in-1 design is highly efficient. However, users who need to penetrate heavy industrial steel or who require a dedicated high-amperage MIG setup for production-scale work should look at higher-output machines. These alternatives offer the higher amperage necessary to surpass the 5.0 mm thickness limit and provide the specialized power required for heavy-duty structural fabrication.

If you are a beginner looking for a versatile, gasless welding solution for thin-to-medium steel projects, the ANDELI 135A is a suitable choice. For those requiring heavy-duty penetration or industrial-grade output, you should consider a higher-amperage MIG welder instead.
