SF-Mobile WeldStar: Precision Welding Made Portable

As our welding machines are high-value industrial equipment, we cannot support returns without a valid reason to prevent fraudulent return claims. However, if returns are necessary due to significant issues on our part, we can accommodate returns under the following conditions:

1. Equipment not yet shipped: We will refund 90% of the equipment value. The customer will need to cover costs related to packaging, booking, and customs declaration that have already been incurred.

2. Equipment shipped but not unpacked: Within one week of receiving the equipment, if it remains unopened and in good packaging condition, we support customers returning the goods to our company or our warehouse in the United States. The customer must bear the return shipping costs, and we can only refund 80% of the equipment value.

3. Equipment shipped and unpacked: Within two weeks of receiving the equipment, if a return is needed due to significant negligence on our part, the customer must bear the return shipping costs, and we can only refund 50% of the equipment value. The remaining portion accounts for equipment depreciation.

We offer a comprehensive 2-year warranty on all SF-Mobile WeldStar models, covering manufacturing defects and non-human-caused damage. Our warranty service works as follows:

1. Small components: For electrical components or small parts that need replacement, we will ship new parts directly to you. Customer is responsible for shipping costs only. Installation guidance will be provided by our technical team.

2. Major components: For major components such as laser generators, cooling systems, control systems, or welding heads that require service, the unit must be returned to our facility in China for repair. Customer is responsible for the round-trip shipping costs, while we cover all repair costs.

3. Consumables exclusion: Please note that consumable items such as copper nozzles, optical lenses, welding wire, and other wear parts are not covered by the warranty as they are considered normal replacement items during operation.

Our commitment is to keep your machine operating at peak performance throughout its lifetime with minimal downtime.

Generally, a single‐wire feeder is sufficient for most welding jobs. However, if you need higher deposition rates, deeper penetration or more precise weld-bead control—especially on thick sections, long seams or critical applications—a dual‐wire feeder is worth the investment.

There is no problem with the single wire feeder.

It is enough to buy the Annual consumables package and protective glasses, there is nothing else to buy.

2000W and 3000W quality is same, which one to choose? It's according to your welding requirements, if you wanna weld thicker sheets, then choose 3000W.

2000W welding capacity: 5-6mm of SS, 5mm of CS and 4mm of aluminum

3000W welding capacity: 8mm of SS, 7-8mm of CS and 5-7mm of aluminum

Gas requirements: If there are requirements for the cutting surface, it is recommended to use nitrogen gas (greater than 6 kg), which will make the cutting surface whiter.

If there have requirements for cutting thickness, use oxygen or air cutting, which will make the cutting surface blacker.

It is not recommended to use argon cutting, which may cause poor cutting effect.

Cutting thickness: preferably less than 3 mm.

Six kilograms is six bar.

Wooden box packing size and weight, L*W*H:

2000W: 164*89*161cm, 256kgs

3000W: 164*89*161cm, 308kgs

Yes, It can ship to your address. The website's automatic freight calculation system is based on FedEx Express, since the welding machine exceeds its maximum weight limit, it showed an "unreachable" error.

The input voltage for 3KW laser welding machine must be 3 phase 380V, while the power can be changed to 2kw, 1.5kw according to your needs.

Regarding the dual wire feeder:

Applicable welding wire: 1.6/2.0/2.5mm

Applicable wire reel:
Shaft diameter: MIN50mm
Outer diameter: MAX300mm
Width: MAX105mm
Weight: <20kg

Note: The price of our welding machine comes with a single wire feeder as a standard configuration. If you need a dual wire feeder, you will need to purchase it separately.

For goggles, we have ones fit over spectacles, please check on our website: Premium Laser Safety Goggles

The power supply for the laser source operates on alternating current (AC).

The 2,000W model looks like a solid match for your current system. The 3,000W unit might work with a transformer, but total draw could push your limits. Let me know if you'd like to explore transformer options or discuss alternatives.

Only the cart is an optional item in the packing list, and there are no problems with the other items. You can see that the word "optional" is written in the options, but we might have forgotten to include it in the picture. The wire feeder is included, but the welding wire needs to be purchased separately. We have a consumable package for the welding machine, which includes protective glasses, copper nozzles and other items. It offers high cost-effectiveness.

For regular carbon steel or stainless-steel welding wires, the wire feed tube and wire feed wheels that come with the machine are suitable.

But when it comes to welding aluminum wires, we suggest using ER5356-grade aluminum wire. This type of wire is a bit harder, which reduces the likelihood of wire jams and deformation.

Additionally, a graphene-lined wire feed tube, like the one mentioned, has a graphite inner layer that can significantly reduce friction, further minimizing the risk of wire jams.

If you're concerned about wire jams when welding aluminum, I'd suggest that once the machine arrives, you can first give it a try with the standard setup. We do have ER5356 aluminum wire available on our website: Premium Aluminum Welding Wire

As for the graphene-lined wire feed tube, our standard configuration comes with a regular tube. You can start with the regular one and if you experience wire-jamming issues, then consider purchasing a graphene-lined one.
