Many customers already have a preferred power when they send us their first inquiry.
Some choose 1500W because they want to control the initial cost. Some request 3000W because they believe the highest power will cover every future order.
The most commonly discussed option is 2000W.
Before preparing a recommendation, we normally ask the customer to send more information.
What material do you use?
What thickness do you weld every day?
What is the thickest material you process occasionally?
What type of joint do you have?
How large is the gap?
What product are you manufacturing?
How many hours will the machine operate each day?
Will welding be the main work, or do you also need regular cleaning and cutting?
Without these details, a power recommendation is only a guess.
The Faith four-in-one laser welding machine is available in 1500W, 2000W and 3000W configurations. It includes welding, simple metal cutting, surface cleaning and weld seam cleaning functions.
All three versions follow the same general working concept, but they do not serve exactly the same customer.
Customers often choose equipment according to the thickest material they have ever processed.
A factory may weld 1.5 mm and 2 mm stainless steel every day, but once every few months it receives an order involving a thicker component.
The owner then wants to select the machine entirely around that rare project.
This may lead to unnecessary investment.
We normally ask customers to divide their work into three groups:
The thinnest material used regularly.
The thickness used for most orders.
The maximum thickness used occasionally.
The second group should have the greatest influence on the decision.
If 80% or 90% of the work involves thin stainless steel, the operator needs good control on thin sheets more than extra power that is only used several times a year.
The material also matters.
Stainless steel, carbon steel, aluminum and copper react differently to laser energy. Aluminum and copper are more reflective and require careful process adjustment. A thickness number without a material name tells us very little.
Joint design also changes the result.
A close-fitting butt joint is different from a corner joint with an uneven gap. A lap joint requires energy to connect two overlapping layers. A T-joint requires stable positioning between two surfaces.
This is why a simple thickness chart cannot replace an application review.
A 1500W handheld laser welding machine is often selected by smaller workshops and customers purchasing laser welding equipment for the first time.
It can be a practical configuration for stainless steel cabinets, kitchen equipment, advertising letters, thin metal boxes, doors, shelves, light furniture and general hardware.
These products normally require clean seams and controlled heat input.
The factory may not need the highest penetration. It needs to reduce grinding, limit deformation and produce a more consistent appearance.
A 1500W machine may make sense when most materials are relatively thin, the daily production volume is moderate and welding is the main function.
It is also suitable when cleaning and cutting are supporting tasks rather than the main business.
Some customers worry that choosing 1500W means the machine will become outdated quickly.
That is not automatically true.
If the factory continues to produce thin stainless steel products, the equipment may remain suitable for a long time. Higher power does not automatically improve a thin-sheet application.
In fact, excessive energy can create new problems.
If the operator moves too slowly or uses too much power, a thin sheet can burn through. The weld can become wider than necessary, and the surrounding area may receive more heat.
A lower-power model should not be described as an inferior machine. It is simply intended for a different production range.
The correct question is not, “Which model is strongest?”
It is, “Which model matches the work we perform most often?”
For general metal fabrication, 2000W is often the most balanced option.
A 2000W customer may produce stainless steel cabinets this week, carbon steel frames next week and custom hardware after that.
The factory may not have one fixed material or product.
The additional power reserve gives the operator more flexibility across changing orders, while the machine remains suitable for common sheet metal fabrication.
Typical users include metal cabinet factories, commercial kitchen equipment companies, furniture manufacturers, door and window workshops, automotive component businesses and general hardware processors.
A 2000W configuration is often chosen because it balances several factors:
Initial investment.
Material range.
Working speed.
Production flexibility.
Future order growth.
This does not mean 2000W is automatically correct for everyone.
It is simply a practical middle point when the customer processes mixed materials and cannot predict one exact workload for the next several years.
A customer once asked us for a 3000W machine because he wanted to be prepared for future expansion.
After reviewing his product photos, we found that almost all of his work involved 1–2 mm stainless steel restaurant equipment.
His real production problem was not a lack of penetration. It was visible deformation and too much polishing after TIG welding.
A 2000W system was a more reasonable match.
The difference in budget could be used for fixtures, safety equipment, fume extraction and spare consumables. These items would improve his daily production more than laser power he rarely used.
This is the kind of decision that cannot be made from a product title alone.
A 3000W laser welding machine is better suited to customers who have a clear and regular need for higher processing capacity.
This may include thicker components, higher daily output, larger metal frames, demanding hardware products and jobs that need more penetration.
It can also be considered when the machine will operate for longer production periods and the customer wants more capacity for cleaning or local cutting tasks.
The important point is that the extra capacity should be used regularly.
If the factory works mainly with thin sheet and operates the machine far below its rated output, the higher investment may not create a useful return.
A 3000W configuration also requires the customer to check the factory conditions.
The electrical supply must be suitable. The cooling system and working environment must support stable operation. Shielding gas and safety arrangements should be planned before delivery.
The operator must also learn how to control the higher output.
More power does not protect the workpiece from incorrect settings.
A 3000W machine can still burn through thin material, create an unnecessarily large seam or increase deformation when the speed and focus are not correct.
Higher capacity creates more possibilities. It also requires responsible control.
Two customers may both say that they weld 2 mm stainless steel, but their applications can be completely different.
The first customer uses accurate laser-cut parts with a stable, close-fitting butt joint.
The second customer manually cuts and bends the sheets. The corner gap changes from one end to the other.
The second job is likely to require filler wire and more parameter adjustment, even though the material thickness is the same.
We normally ask for photos of the joint from several angles.
The machine supports butt, T-joint, fillet, edge and lap welding.
Each joint changes the way energy enters the material.
A lap joint must connect an upper and lower sheet. A fillet weld requires the operator to hold the beam between two surfaces. A butt joint with a gap may need wire to fill the opening.
This is why we are careful about promising exact results before seeing the workpiece.
An application photo is often more useful than a long written inquiry.
The standard wire-feeding range listed for the Faith machine is 38–600 mm/min.
Not every weld needs filler wire.
When the parts fit closely, fusion welding may create a narrow and clean seam without added material.
Wire feeding becomes useful when the gap is larger, the edge condition is inconsistent or the joint needs additional filling.
The wire speed must be matched to the welding speed.
If the feeder supplies too much wire, the seam can become raised and uneven. If it supplies too little, the opening may remain visible.
The wire material should also be compatible with the base metal and the required joint performance.
Customers sometimes ask us to recommend one fixed wire speed for all products. This is not realistic.
A stainless steel corner joint and an aluminum butt joint require different settings. Even products made from the same material may need adjustment when the thickness or gap changes.
During installation and testing, the operator should record the successful combination of power, welding speed, focus and wire feeding.
These records become a useful internal process guide.
They can influence the selection, but the main production process should remain the priority.
If the customer spends 90% of the time welding thin stainless steel, it does not make sense to select the highest power only because the machine also has a cutting mode.
The cutting function is intended for local trimming, small openings, edge corrections and repair work.
It is not a substitute for a dedicated fiber laser cutting machine used for complete sheets, complex patterns and high-volume production.
The cleaning mode can remove rust, oxide, paint and weld discoloration. These applications are included in the product information.
Higher power may help with some more demanding cleaning tasks, but performance also depends on the layer, scan width, speed and cleaning head settings.
We normally ask the customer to estimate how the machine will be used.
For example:
“80% welding, 15% cleaning and 5% cutting.”
“60% welding and 40% repair cleaning.”
“Almost all welding, with occasional weld seam treatment.”
This information helps determine whether the four-in-one design is suitable and whether additional power will actually be used.
Some buyers spend a lot of time discussing the machine and very little time checking the installation site.
Before selecting the final configuration, the customer should confirm the local voltage, frequency, available electrical capacity, shielding-gas supply, factory temperature, working space and ventilation.
Laser safety arrangements must also be considered.
The working area should prevent untrained people from entering during operation. The operator requires suitable protective equipment, and the factory should manage reflected laser energy carefully.
Fume extraction may be necessary when welding, cutting or cleaning coated, oily or painted metals.
These are not optional details to consider after the machine arrives. They are part of the purchasing decision.
A well-selected machine can still perform poorly if the factory supply is unstable or the working conditions are not prepared.
The Faith system uses a water-cooling design and includes a handheld head with red-light positioning and a quick nozzle interface.
These features support flexible operation, but the surrounding production conditions remain the customer’s responsibility.
For many thin-sheet products and smaller workshops, 1500W can be a sensible entry point.
For mixed materials, changing orders and general metal fabrication, 2000W is often the balanced choice.
For higher output, thicker workpieces and customers who regularly need additional capacity, 3000W may be justified.
This is only a starting recommendation.
We do not like to guarantee a welding result from the power number alone.
Material composition, thickness, surface condition, gap, joint type, wire, gas and required appearance all affect the final seam.
The best way to confirm the choice is to test a real sample.
A useful inquiry should include the material name, common thickness, maximum thickness, product photos, joint photos, approximate gap, daily production volume and current welding method.
The customer should also explain whether the final seam is visible and how much polishing is currently required.
If cleaning or cutting will be used regularly, those applications should be described as well.
Local voltage and the country of installation are necessary for the final configuration.
With this information, we can make a recommendation based on the real production situation.
Without it, we can only send a general quotation.
The largest laser welding machine is not always the best investment.
A 1500W machine used efficiently every day can create more value than a 3000W system that rarely needs its full output.
The correct selection begins with understanding the work, not choosing the highest number on the product page.
