What Size Welder Do I Need For 1/4 Steel? When buying a welder, consider the following as general rules: A 140-amp unit can weld up to about 1/4” steel. A 180-amp unit can weld between 3/8” and 5/16” steel. A 200-amp unit can weld between 5/16” steel.
How big of a welder do I need for 1/4 inch? Welding 1/4-inch steel in a single pass requires roughly 180 amps. The phrase in a single pass is the key. Because a series of thin passes can be made to weld thicker material per pass, less amperage is required. However, multiple passes take more time.
What kind of welder do you use for 1/4 steel? Metal Inert Gas (MIG) welding or Gas metal arc welding (GMAW) is a type of welding method in which an electrical arc forms between a consumable wire electrode and the workpiece metal or metals.
Product specs:
Processes MIG (GMAW), Flux Cored (FCAW)

How thick of metal can you stick weld?
A: A 225- to 300-amp stick machine handles almost anything the average person will encounter, as most stick welding procedures require 200 amps or less. To weld material thicker than 3/8 inch, simply make multiple passes — this is what professionals do, even when welding on 1-inch structural steel.
How do I know what amp to weld at?
The specific amperage to be used depends primarily on the diameter of the electrode. For example, an eighth in diameter electrode welds great between 75 and 125 amps. Whereas a 5/32 diameter electrode can weld optimally at up to 220 amps.
