Kg 13. Kg Company Profile We Founded in 2009, ALPHA is formerly the largest OEM manufacturer of industrial-grade welding and cutting power supplies in China, the company boasts over 80000m2 of standardized factory space and state-of-the-art production and testing equipment.

With more than 400 employees, including a team of experienced engineering and technical personnel, the company produces nearly 500000 sets of industrial-grade welding and cutting power supplies annually.

Equipment ALPHA specializes in providing a wide range of welding and cutting equipment, including manual welding, gas shielded welding, plasma cutting, argon arc welding, submerged arc welding and stude welding.

These products are widely used in industries such as construction machinery, petro-chemicals, steel structures, shipbuilding, power, steel, machining, and construction installation. All products have passed the CCC certification, and export products have obtained CE certificate.

Domestically, the company has established over thirty provincial-level general agents and a comprehensive pre-sale, and after-sale sevice system. Products are also exported to Southeast Asia, Europe, the Middle East, and other countires and regions.

Idea We always adhere to the fundamental philosophy of 'winning reputatio with quality, gaining market with integrity, and achieving efficiency through service'.

With service as our guarantee, we provide customers with comprehensive welding and cutting solutions, striving to become the most professional and influential welding and cutting brand in China Certifications FAQ 1. Q: What types of welding machines do you offer?

A: We offer a wide range of welding machines to meet various welding needs. Our product range includes MIG Welders, TIG Welders, Stick Welders and Multi Process Welders. In addition, we also provide Plasma Cutters. Each machine is designed to deliver excellent performance and reliability. 2. Q: Our advantage ?

A: OEM/ODM is available. Small order is acceptable, even 1 piece. Quick Delivery is available in 45 days. 3. Q: What is your warranty terms? A: We provide 1 year warranty time for the whole machine since you received it. During the time, we will supply you the free spare parts for maintanence.

Meanwhile, we offer on-line technical supports for operating guide and troubleshooting. 4. Q: Can I use my ALPHA welder on the generator ? A: Yes, we can. While the welder may operate OK on lower output etc - the fact remains that using an underpowered generator does increase the risk of damage to the welder. 5.

Q: How about the payment terms? A: We accept T/T, LC, O/A and others. 6. Q: What is Hot Start, Arc Force & Anti-Stick? A: What is Hot Start ? Hot Start is a special feature for MMA (stick-electrode) welding where the machine delivers a peak of current when striking the arc.

This is important as it significantly increases the ease of starting electrodes, especially in difficult conditions such as damp electrodes, imperfect job surface, or when using 'difficult to run' electrodes, etc. What is Arc Force ?

Arc Force, sometimes called "Dig" or "Arc Control", is a similar feature to Hot Start, except Arc Force operates during welding, not just at ignition. When the welding machine senses a short circuit it will deliver a peak of current.

This greatly assists in stabilizing the arc, preventing the arc from cutting out while welding and preventing electrode sticking. What is Anti-Stick ? Anti-Stick allows the stick welding electrode to be easily detached, if it does begin to stick to the job.

When the machine senses that the electrode is sticking, it will collapse the welding current to stop the electrode from continuing to weld itself to the job, allowing it to break free easily. Chengdu Alpha Welding & Cutting Equipment Co., Ltd.
