In average you need 140 amps for 115 volts welders in order to weld up to ¼” thick steel and around 200 amps for 220 volts welders and weld up to ½” thick material.
How many amps do you need to weld steel?
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.Jan 1, 2008

How thick can a 120 amp welder weld?
All-in-one 120-volt wire welder that welds 24 gauge to 3/16-inch-thick (0.8-4.8 mm) mild steel in a single pass. Welds material from 24 gauge to 3/8-inch thick in a single pass. Multi-voltage plug (MVP™) provides versatility to use 120- or 240-volt input power.
What size breaker do I need for 200 amp welder?
50A breaker
How many Amps does a 220v welder draw?
A 220v welder will take about half the amperage of a similar 110v welder. 90-100 amps is fairly common, but you can find smaller (and larger) welders. An air compressor will probably take a lot less current, maybe 20-30 amps for 220v or 20-50 amps for 110v.
How many watts does a 200 amp welder use?
So to be able to weld at 200 amps, you would need a consistent 5,000 watt power source at 208 - 240 volts, and the start in rush current can hit 36 amps at 240 volt, or about 9,000 watts for a second or so.
How many Amps does a 240v welder use?
A 50-amp circuit breaker and 6-gauge wiring is required for welders with 40 to 50-input Amps. Welders need a 40-amp breaker and 8-gauge wire to operate. Small welders can use 10-gauge wire with a 30-amp circuitbreaker.
How thick can a 200 amp welder weld?
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.
