How thick can a 250 amp MIG welder weld?
You'd easily get between 8-10MM on a 250A set, mild steel that is.
As a guideline, each . 001 inch of material thickness requires 1 amp of output, so welding a base material that is . 125-inch thick requires 125 amps, while welding material that is . 250-inch thick (1/4 inch) would require 250 amps.
The technical name for it is gas metal arc welding (or GMAW), and the slang name for it is wire welding. The MIG process enables the artist, farmer/rancher, motorsports enthusiast or DIY welder to make most types of fabrication and maintenance/repair welds on material from 24-gauge up to 1/2-inch thick.
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.
Shikha 250 AMP Welder Dual Volt Arc Stick Welding Machine
It runs off a standard 110 / 220 volt industrial input power and produces an welding range of 20~250 A with 60% duty cycle.
If you need a cable to weld using about 200-250A at 30-60% duty cycles, this AWG 2 cable from EWCS is a good choice.
To weld medium-thickness metal up to 1/2" or 1/4", you will need a 200-250 amp rated welder with 220V input. These machines have enough power to join thicker metal with ease and our recommendation is YesWelder MIG-205DS.
Stick welding produces stronger welds than MIG welding as it can better penetrate thicker metals and dirty surfaces.
Always push the weld puddle when MIG welding aluminum, so that the shielding gas covers the weld puddle sufficiently. Pulling an aluminum weld puddle will result in a dirty, porous weld due to insufficient gas coverage.
In general, a fillet weld made with E70 electrodes will provide a service level load capacity of 0.928 kips per inch per 1/16" of weld size.
How thick of steel can you weld with 200 amps?
A 200-amp unit can weld between 5/16” steel. A 250-amp unit can weld 1/2” steel.
► 225 amp AC output - Is enough for 3/16 in. (4.8 mm) diameter general purpose mild steel electrodes and 5/32 in.
Fine Touch and Low Heat for Sheet Metal
For thicker material, an AC/DC TIG welder making 225 amps can weld 1/2-inch metal.
A 180-amp unit can weld between 3/8” and 5/16” steel. A 200-amp unit can weld between 5/16” steel. A 250-amp unit can weld 1/2” steel.
Current setting
For example, a 1/8-inch 6010 rod runs well from 75 to 125 amps, while a 5/32-inch 7018 rod welds at currents up to 220 amps.
Regarding your first question, “Why can't I stick weld with my MIG machine”, the answer is because your MIG machine only has CV output, which is not intended or recommended for stick welding.

1/8 fillet weld: weld strength = 1.856 kips per inch of weld. 3/16 fillet weld: weld strength = 2.784 kips per inch of weld. 1/4 fillet weld: weld strength = 3.712 kips per inch of weld. 5/16 fillet weld: weld strength = 4.64 kips per inch of weld.
Unsuitable for Thick Metals
While MIG welding is suitable for thin metals, it does not deliver proper penetration for thicker steel that requires a solid weld.
Stick welding is considered one of the most inexpensive forms of welding, while MIG welding tends to cost more due to its high number of consumables (and downtime required to change them.) That cost may be somewhat offset, however, by the long welds that are possible because of the MIG gun's continuously feeding wire.
In contrast, MIG welding is faster and more efficient, and cleaner than stick welding. However, MIG machines are more complicated to set up and learn, and are also usually more expensive.
The majority of MIG welding is done with a gas shield — carbon dioxide and argon/CO2 mixes are the most common. The gas bottle has a regulator or flowmeter to set the gas flow. There are many variables here, but a good rule of thumb for light-duty welding is to use about 20 cubic feet per hour of gas flow.
For wire (flux-core or MIG) welding, keep a work distance of ⅜ to ½ inch. With stick welding, look to keep that distance ⅛ inch between the rod tip and work piece.
- Keep a 1/4 to 3/8 in. ...
- For thin metals, use a smaller diameter wire. ...
- Use the correct wire type for the base metal being welded. ...
- Use the proper shielding gas. ...
- For steel, there are two common wire types. ...
- For best control of your weld bead, keep the wire directed at the leading edge of the weld pool.
TIG welding is the hardest form of welding to learn for a variety of reasons. The process of TIG welding is slow and takes time to get used to as a beginner. A TIG welder requires a foot pedal to feed the electrode and control the variable amperage while maintaining a steady hand at the welding torch.
There's a common misconception that welding is stronger than bolting, but that simply isn't true. Bolting is just as strong as welding—and can be stronger in some situations. The strength of a weld is largely determined by the expertise of the welder.
What is the strongest weld ever?
TIG welding is often considered the strongest weld since it produces extreme heat, and the slow cooling rate results in high tensile strength and ductility. MIG is also an excellent candidate for the strongest type of weld because it can create a strong joint.
| Maximum Amps | 90 amp | 150 amp |
|---|---|---|
| Max Steel Thickness (butt weld) | 2.0mm | 4mm |
| Max Steel Thickness (with V and root gap) | 3.0mm | 6mm |
Many people consider any wires 1/16 inch and up to be large-diameter wires. While numerous structural fabrication applications use 5/64-inch gas-shielded flux-cored wire (FCAW-G), be aware that a wire size larger than 1/16 inch often limits out-of-position welding capabilities.

It is excellent for thin sheet metal and heavy gauge steel up to 1/4 thick. With 120-Volt/240-Volt capabilities, this welder can be operated almost anywhere a power outlet is found and can be used with small clean powered generators.
The strength of the weld is determined by the filler metal used and its effective area. The effective area of a weld is determined by multiplying the length of the weld times the throat. So the bigger the throat the larger the effective area and thus the stronger the weld.
How thick can a 225 amp welder weld?
This machine can weld up to 5/16-7018 (Low Hydrogen) and up to 3/16 Mild Steel.
The maximum size of fillet weld is generally that of the thickness of the thinner of the two items being joined but very large fillet welds may cause unacceptable distortion and/or extremely high residual stresses. In addition, above a certain size it may be more economical to make a T-butt, rather than a fillet weld.
The Millermatic 255 MIG welder is built for professionals in the light manufacturing or fabrication segments who are looking for a smaller, more versatile machine.

If the weld is 8" long, the weld is good for 22.272 kips, or 22,272#. A 1/4 fillet is good for 3.712 kips per inch (4 x . 928), a 5/16 fillet is good for 4.64 kips per inch (5 x . 928), and so on.
Thick structural steel and pipe thicker than a half-inch require the use of a heavy-duty MIG welding machine or a stick welder. According to Miller Electric, you need one amp of power for every one-hundredth inch of mild steel thickness.
There is NO max size of fillet weld for a T-joint, to AWS and AISC specifications. The max fillet weld rules are for 'edges' - so that the edges are not melted. For a T-joint there are no 'edges', just 'surfaces'.
Accordingly, when the plate is 1/4 in. (6 mm) or thicker, the maximum fillet weld size is 1/16 in.
