Manual Welding Machine Purchase Guide: Price Analysis and Operation Specification Details

 

As a core tool in the fields of industrial manufacturing and maintenance, the performance and operation specifications of manual welding machines directly affect the quality of work. This article will provide professional guidance for practitioners from three dimensions: equipment purchase skills, market trend analysis, and standardized operation procedures.

 

I. Analysis of the Brand Selection Dimension

In the field of industrial equipment, the domestic market has formed an industrial pattern dominated by professional manufacturers. Domestic manufacturers with the R & D ability for heavy - duty equipment have outstanding performance in terms of thermal stability and welding accuracy for their manual welding machines, gas shielded welding machines, and laser welding equipment, thanks to the adoption of full - digital control technology. In the international market, Japanese brands are known for their high cost - effectiveness, American brands maintain a technological advantage in high - intensity operations, and European products are usually equipped with intelligent control systems. In actual purchasing, it is necessary to combine the application scenarios. Metal processing plants are recommended to choose industrial - grade gas shielded welding machines, while home improvement and maintenance should focus on portable mini - models.

 

II. Analysis of the Market Price Gradient

The current market presents a diversified price distribution, mainly determined by the equipment power and functional modules:

1. Basic equipment: Hand - held models below 1500W, supporting 220V voltage, suitable for thin - plate welding, with prices concentrated in the range of 500 - 2000 yuan.

2. Advanced industrial equipment: Medium - power models from 1500W - 3000W, equipped with digital displays and dual - voltage systems, with market quotations ranging from 8000 - 20000 yuan.

3. Professional - grade systems: Intelligent equipment integrating laser welding modules, suitable for special - metal processing, usually priced at over 50000 yuan.

There are obvious price differences in online procurement channels. The wholesale price of industrial - grade equipment on B2B platforms is 15% - 20% lower than that on retail channels, and cross - border e - commerce channels often include models with international certifications.

 

III. Standardized Operation Procedures

(1) Safety Pre - treatment Stage

- Check the stability of the power supply system, and the grounding resistance should be ≤4Ω.

- Wear a full set of protective equipment: ANSI Z87 - certified welding helmets, flame - retardant gloves, and chemical - resistant aprons.

 

(2) Equipment Parameter Setting Specifications

- Select the current according to the material thickness: 40 - 50A corresponds to each millimeter of steel plate.

- Adjust the voltage based on the wire diameter: A 1.2mm wire matches 18 - 22V.

- Control the argon gas flow rate at 8 - 15L/min (TIG welding).

 

(3) Key Points in Operation Implementation

- Keep the welding gun at an inclination of 70° - 80° and a running speed of 8 - 12cm/min.

- For multi - layer welding, control the inter - layer temperature below 150°C.

- For carbon steel operations, it is recommended to use E7018 electrodes, and for stainless steel, use ER308L wires.

 

(4) Equipment Maintenance Regulations

- Remove the spatter on the contact tip after daily operations.

- Check the wear of the wire feeding mechanism weekly.

- Replace the filter screen of the cooling system regularly.
