A 120 amp welder can typically weld steel thicknesses ranging from 18 gauge (approximately 1.2 mm) to about 1/4 inch (6.35 mm) depending on the type of welding process used (like MIG or stick) and the welder's settings. For optimal results, it's best to stay within the lower end of this range for consistent penetration and weld quality. Always consider factors like joint design, welding technique, and the specific type of steel being welded.
What does the schedule have to do with the material as schedule is the wall thickness Schedule 10, 20, 40 80 and 120 (XXH) The Schedule is telling you the wall (INTERNAL) thickness 10, 20 40, 80 and 120 XXH Whether it be steel, brass, galvanized and wrought ` About the pressure capacity, it is not the same because every material such as steel, brass, galvanized or wrought has a different strenght of materials.
It is approx 4.7 inches.
depending on the thickness of steel you have to change your amperage.... i like to work with 120 or higher with 1"1/2 angle iron The thump rule for any welding rod current selection is as follows: Current = Core wire Dia of the Electrode X 40 Example (4mm X 40 = 160 Amps ) Current shall be lowered & increased based on the welding position & Job thickness etc and also depends on the welder skill & job nature +/- 10 to 20% on the above.
Generally, steel pipe, not less than Sch. 40, A-53 or A-120 ERW or DOM. Steam Condensate pipe is sometimes specified at Sch. 80. Steam pipes normally black steel sometimes copper tubing Depending on the pressure what wall thickness is required I installed piping black steel schedule 40 to schedule 120 with steam valves rated to 3000 #
120 lb paper is typically around 0.003 inches (0.076 mm) thick. The weight of paper is a measurement of its density, not its thickness, so the thickness can vary depending on the type of paper and its composition.
No, unless you can set it low and can be assured that it wont use more than say 4000watts, the welder might momentarily use more power than what you set it to, it should not wreck the welder i would imagine unless it is a fancy mig welder or something, set the welder low you should be fine but for high end use she should be firing out 8 or 9kw so keep it low if you must.
What schedule 10 ,20, 40, 80, 120????
The diameter is 120 millimetres. The thickness depends on whether or not it can be written to.
For a 120-amp, 120-volt arc welder, you typically need a double-pole circuit breaker rated for at least 30 amps. This allows for the necessary current flow while providing adequate protection against overloads and short circuits. It's also important to use appropriate wiring to handle the current safely. Always consult the welder's manual and local electrical codes for specific requirements.
What is "it"?What is it? Wire? Sheet metal? What?PolytheneIn the case of polythene, gauge can be converted to thickness by dividing by four to get the thickness in micron or dividing by 4000 to get the thickness in mm. Here are some common examples:100 gauge = 25 micron = 0.025mm 120 gauge = 30 micron = 0.03mm 200 gauge = 50 micron = 0.05mm 250 gauge = 62.5 micron = 0.0625mm 400 gauge = 100 micron = 0.1mm
Not recommended.
