Frequently Asked Questions

Which machine for aluminum?

Two picks only: the SD-4050Pro (pulse MIG) and TIG-250AC (AC/DC TIG). Standard MIG and stick machines cannot break aluminum's oxide layer reliably - this is the one spec that truly filters the lineup.
What welds stainless steel best?

TIG first (cleanest, TIG-250AC or TIG-200A), MIG with 308L wire second. Back-purge with argon on food-grade or visible work keeps the underside from sugaring.
I weld a mix of metals - what should I own?

A multi-process machine: MIG for mild steel, TIG or stick modes for stainless, pulse MIG or AC TIG for aluminum on the flagship models. The Multi-Metal Welders collection lists them.
Does metal thickness matter more than metal type?

They filter together: type decides process (and gas), thickness decides amperage and wire/rod size. The shop-by-metal collections pair each metal with machines that have the amp range for common thicknesses.

Faqs

Which welder is best for stainless steel?

TIG welding is ideal for stainless steel due to its precision and clean welds.
Can I weld aluminum with a regular MIG welder?

You’ll need a MIG welder with a spool gun or a TIG welder to properly weld aluminum.
What type of welding is best for steel?

MIG and Stick welding are the most common choices for steel, depending on thickness and application.
Do I need a special machine for welding different metals?

Some welders support multiple metal types, but aluminum often requires specific features like AC TIG.
How do I choose the right welder for my metal type?

Consider the metal's thickness, conductivity, and the welding process—our product pages provide guidance.
