Deca SIL 417 Arc Welding Machine with 10 A to 170 A Welding Current, 7.8 kVA Power Consumption, and 230 V AC Input Voltage

The Deca SIL 417 arc welding machine is an advanced inverter-technology direct current STICK arc welder designed for efficient metal joining and fabrication tasks. Engineered for versatility, it supports both direct and inverse constant welding current output, enabling users to work with a wide variety of electrodes and metals including rutile, basic, stainless steel, and cast iron. It also features TIG Scratch striking capabilities, making it ideal for tasks requiring high precision on materials such as steel, stainless steel, copper, and nickel.

Advantages

This welding machine integrates several advanced functions to improve operational reliability and weld quality. The Hot Start function temporarily increases the welding current during arc ignition to facilitate striking, prevent metallurgical defects, and avoid electrode sticking. The Anti-Sticking mechanism automatically reduces the welding current if the electrode sticks to the workpiece, making it easier to detach. Additionally, the Arc Force feature manages droplet transfer to maintain arc stability and prevent the arc from stopping during operation. Built-in thermostatic and overvoltage protections ensure safe usage, and the unit can be safely connected to motor generators with controlled output voltage.

Suitable for

• General metal fabrication and repair work
• Workshop maintenance and mechanical repairs
• DIY metalworking projects requiring stable arc performance
• Welding with rutile, basic, stainless steel, and cast iron electrodes
• Precision TIG welding applications on steel, copper, and nickel

When it may not be suitable

This arc welder may not be suitable for heavy industrial production lines requiring continuous high-amperage operation beyond its rated capacity. It is also not designed for advanced TIG welding processes that require high-frequency arc striking instead of scratch striking.

Key specifications

• Adjustable welding current ranging from 10 A to 170 A
• Power consumption of 7.8 kVA
• Input voltage of 230 V AC at 50 to 60 Hz
• Minimum supported electrode diameter of 1.6 mm
• Direct current STICK and TIG Scratch welding capabilities
• Includes a 2.0-meter supply cable with a plug

How to use

To operate the Deca SIL 417, first ensure that the input voltage matches the 230 V AC power source and that the unit is properly grounded. Connect the appropriate welding leads and select the desired electrode type or TIG setup based on the metal being joined. Adjust the welding current between 10 A and 170 A according to the material thickness and electrode size. Turn on the machine, strike the arc using the appropriate method, and maintain a steady travel speed along the joint while utilizing the built-in arc management features for stable execution.

What to consider before purchase

• Verify that your power supply meets the 230 V AC requirement and can support the 7.8 kVA power consumption
• Check the compatibility of your intended electrodes and metals with the supported types
• Ensure the maximum 170 A output is sufficient for your typical material thicknesses
• Confirm whether scratch-start TIG or STICK welding aligns with your project requirements

Always wear appropriate personal protective equipment, including a welding helmet, gloves, and protective clothing, and operate the machine in a well-ventilated area free from flammable materials.
