1. Welding ability

Two-gun bolt welder: As the name suggests, this type of welder is equipped with two independent welding systems and is capable of handling two welding points at the same time. When two bolts or two welding areas need to be welded at the same time, the double gun welder can significantly increase the welding efficiency.

Three-Gun Bolt Welder: Compared to the double-gun welder, the three-gun welder goes one step further and has three independent welding systems that are capable of handling three welding points at the same time. In the case of greater welding demand and higher efficiency requirements, the advantages of three-gun welding machine are more obvious.

Second, the structure and complexity of the equipment

The difference between double gun and triple gun: from the perspective of equipment structure, the three-gun welder has one more welding system than the double-gun welder, so its overall structure may be more complex and the floor space may be larger. At the same time, the control system of the three-gun welding machine also needs to be able to process the data of three welding points at the same time, and the requirements for control technology are also higher.

3. Operation and maintenance

Difficulty: As the number of welding guns increases, the difficulty of operation may also increase. Three-gun welders require operators to be able to monitor and adjust the status of three weld joints at the same time, which may require higher operational skills and experience.

Maintenance costs: Due to the more complex structure of the three-gun welder, its maintenance cost can also be relatively high. Routine maintenance, troubleshooting, and replacement of parts can be more cumbersome and expensive than a double torch welder.

4. Applicable scenarios

Double-gun bolt welding machine: suitable for scenarios that require simultaneous welding of two bolts or two welding areas, such as part of the welding task in automobile manufacturing, shipbuilding and other industries.

Three-gun bolt welder: more advantageous in the occasion of greater welding demand and higher efficiency requirements. For example, during the manufacture and installation of large steel structural parts, it may be necessary to weld multiple bolts at the same time to ensure the stability and safety of the structure. At this time, the application of the three-gun welder will be able to significantly improve the welding efficiency and reduce the production cost.

Fifth, cost-effectiveness

Purchase cost: Generally speaking, the purchase cost of a three-gun welder will be higher than that of a double-gun welder because of its higher technical complexity and manufacturing cost.

Running costs: During operation, the difference in cost between the two may be mainly reflected in energy consumption and consumables consumption. Since a three-gun welder has more welds working at the same time, its energy consumption and consumables consumption may also be higher. However, this does not mean that a three-gun welder is necessarily less cost-effective than a two-gun welder. In the case of high welding demand and high efficiency requirements, the efficiency increase and cost reduction brought by the three-gun welder may be more than enough to compensate for its higher purchase and operating costs.

To sum up, the differences between two-gun and three-gun bolt welding machines are mainly reflected in welding capacity, equipment structure and complexity, operation and maintenance, applicable scenarios, and cost-effectiveness. When choosing, it is necessary to consider comprehensively according to the specific welding needs and scenarios.
