Frequently Asked Questions

What processes does the MCT520 support?
The MCT520 combines Synergic MIG, Manual MIG, Flux-Core, Spool Gun Aluminum MIG, HF TIG, Stick, and plasma cutting.
What welding and cutting output does the MCT520 provide?
The MCT520 supports up to 200A welding output and 20-50A plasma cutting output.
What cut capacity does the MCT520 offer?
The MCT520 delivers clean plasma cuts up to 5/8 inch with proper setup.
Can the MCT520 MIG weld aluminum?
Yes. The MCT520 supports aluminum MIG welding. For best results, use a spool gun or a standard MIG torch fitted with a graphene liner to ensure smooth and reliable aluminum wire feeding.
What gas options does the MCT520 support?
Gas requirements depend on the welding process. Flux-cored welding is gasless. For MIG welding, the machine supports CO2, 100% CO2, and mixed shielding gases (such as Ar/CO2 blends). Shielding gas is not required for flux-cored welding.
Does the MCT520 have a gas check function?
Yes. Press the Gas Check button to test shielding gas flow before welding, ensuring proper gas coverage without starting an arc.
