4. Wuxi JACK, the Top Grade Chinese Producer on 3 in 1 H Beam Welding Fabrication Machine:

1) As a technique based company in Steel Structure, Welding and Cutting Industry, with over 2 decades history, Wuxi JACK is the first Chinese Supplier on H Beam Welding 3 in 1 Machine, who took the lead on develop this machine and put into market in the year 2009, and has delivered over 400 sets for customers with delicate design and superior quality, around 20 sets every year:

B. Welding Power Supply Options from Chinese Producer on 3 in 1 H Beam Welding Fabrication Machine:

1. Importance: Welding power supply is critical outsourced function unit for the machine, performing finished welding on assembled H Beam. During technical discussion between customer and producer on the machine, this unit need to be confirmed on its origin (brand), type (welding mode), and model;

2. Option 1 Welding Modes for H Beam Welding 3 in 1 Machine: SAW:

1) How to Select? The first step is to decide on which kind of welding to be adopted. This is based on the max. specification of H Beam to be fabricated:

2) As can be observed from the above parameter table, the max. thickness of H Beam flange and web are 40mm and 32mm respectively. This can only be achieved with SAW- Submerged arc welding:

3) SAW in the process of fabricating welding H Beam in Wuxi JACK H Beam Welding 3 in 1 Machine: (Fig.4)

4) The Technical Characteristics of SAW:

a) Large welding current --- Up to 1000A, often with working current of 500A ~ 700A;

b) Applicable for welding on large thickness plate, especially in the range of 20mm ~ 40mm, meeting the demand on medium to heavy duty H Beam production;

c) User and environment friendly operation --- No welding light and low noise level;

For these reasons, SAW account for over 90% of welding mode in application of H Beam Welding 3 in 1 Machine. In other words, default setting of the machine:

3. Option 2 Welding Modes in 3 in 1 H Beam Welding Fabrication Machine: GMAW:

1) When to Use? In the field of light duty small steel structure production, namely plate thickness less than 12mm, and the minimum 3mm, SAW is not suitable here for welding. The more proper choice is GMAW CO₂:

2) GMAW CO₂ in Wuxi JACK ZHJ10 H Beam Welding 3 in 1 Machine: (Fig.6)

3) Technical Features of GMAW CO₂ Welding:

a) Certain Harm on People Health: As can be observed from the above photo, GMAW CO₂ generates strong arc light. So, operator need to put on helmet as facial mask. Besides, the welding noise level of GMAW CO₂ is high, so, ear plugs need to be used, when 3 in 1 H Beam Welding Fabrication Machine carries out GMAW CO₂ gas shielded welding;

b) Strong intensity welding seam: The GMAW CO₂ gas shielded welding has high IK value (Anti-impact), which promises strong intensity welding seam acquired from thin plates. So, it is often used in Ship building industry, which has high demand on welding strength;

As complement on SAW, GMAW CO₂ gas shielded welding takes up around 10% use of H Beam Welding 3 in 1 Machine:

4. Origin (Brand) of Welding Power Supply in 3 in 1 H Beam Welding Fabrication Machine:

Now that we know how to select welding mode for the machine, the next step is to select supplier, which means brand of welding power supply:

1) Option 1: American Lincoln brand for SAW:

a) Over 10~ 15 year ago, which is 2009 year to 2014 year, this is major configuration recommended by Chinese Producer on 3 in 1 H Beam Welding Fabrication Machine;

b) The reason is, as international renowned brand, Lincoln is recognized by user across the globe, which has high standard stable performance, and easily serviced at every market:

c) American Lincoln brand PowerPlus-1000HD welding power supply: (Fig.8)

d) The disadvantage of Lincoln is its high price, and relative long lead time for Chinese Producer on H Beam Welding 3 in 1 Machine, because this brand power supply is produced in America and distributed to other nations. However, due to its superior quality, Lincoln was mainstream configuration in the 2010s;

2) Option 2: Japanese Panasonic brand for GMAW:

a) Every brand has its strong product. When customer select CO₂ GMAW for producing light duty steel, Japanese brand Panasonic is preferred choice for customers;

b) This is also true with the condition 10~ 15 years ago, that when Chinese Supplier on H Beam Welding 3 in 1 Machine communicate with steel structure customers on GMAW welding, recommendation on brand of power supply is Panasonic. The reason is same as Lincoln in case of SAW: High quality and renowned reputation:

c) Panasonic KR500 welding power supply: (Fig.9)

d) The downside of Panasonic is also high cost;

3) Option 3: Rising Start on Welding Power Supply: Chinese HUAYUAN Brand for SAW and GMAW:

a) Catch Up from Behind: Things always change with time going. Over the past decades, the Chinese producers on welding power supply catch up with overseas famous brand, in terms of quality and performance. And in the field of 3 in 1 H Beam Welding Fabrication Machine, the most eye catching rising star is HUAYUAN brand:

b) HUAYUAN NB-630HD welding power supply: (Fig.10)

c) The Strong Points of HUAYUAN:

i. The same superior quality performance as international famous brand Lincoln and Panasonic nowadays;

ii. Provide both welding modes: SAW and CO₂ GMAW in different models;

iii. Much more reasonable cost of welding power supply itself, together with consumables (Welding torch, contact tube, etc.): Only one fifth that of Lincoln for SAW, and one third of Panasonic for GMAW;

iv. Much more short lead time, benefitting from local production;

Because of the above strong points, nowadays HUAYUAN is the first recommendation on supplier on welding power supply, by Chinese Supplier on 3 in 1 H Beam Welding Fabrication Machine.

C. Wuxi JACK Achievement and Strength as Top Chinese Producer on H Beam Welding 3 in 1 Machine:
