MIG Pulse Welding Machine Manufacturers

Introduction / Quick Summary

Today's fabrication and manufacturing industries demand the highest levels of productivity while preserving full control of heat input, arc behavior, and weld appearance. MIG pulse welding machines, a class of sophisticated wire-feed welding equipment, operate by pulsed flow of controlled current to transfer molten metal from the welding wire to the work.

What Is a MIG Pulse Welding Machine?

A MIG pulse welding machine is a type of gas-metal arc welding machine where a controlled pulsed current waveform governs the transfer of metal from a continuously fed wire electrode to the workpiece.

MIG is the abbreviation for the process Metal Inert Gas welding, but modern systems may use various types of other shielding gases depending on material and process. The welding wire is the electrode.

In pulse MIG, the power source maintains the current in pulsed mode. The goal is to transfer precise amounts of molten metal from the wire while keeping the arc during the lower-current part of the cycle.

A typical MIG pulse system includes:

• Welding power source
• Inverter or electronic control system
• Wire-feed unit
• Welding torch
• Shielding-gas system
• Control panel
• Welding cables
• Earth cable
• Cooling system
• Digital parameter controls
• Welding software/control circuitry

Why MIG Pulse Welding Machines Matter

Pulse MIG technology can help in situations where a conventional MIG process fails to give the necessary balance of heat input, weld appearance, and efficiency.

1. Controlled Metal Transfer

A pulsed current controls the metal transfer as the molten metal moves from the wire to the workpiece.

2. Reduced Spatter

Correct pulse settings can decrease undesirable spatter compared with some conventional transfer modes.

3. Better Heat Control

Pulse welding offers control of heat input, which may be advantageous when welding thin sections or heat-sensitive applications.

4. Improved Weld Appearance

If pulse welding is properly set up, it can make very smooth welds that look consistent.

5. Suitable for Aluminium

The benefit of using Pulse MIG is that it is great for aluminium if the machine, wire, shielding gas, torch, and the parameters are all in harmony.

6. Suitable for Stainless Steel

Pulse control offers some useful benefits in heat management for certain stainless-steel welding operations.

7. Productivity

The continuous wire feeding will enable you to have long, uninterrupted runs of welding, unlike the MMA process where you would have to change electrodes regularly.

8. Automation Compatibility

The MIG pulse welding process could be adopted in semi- and fully mechanised and robotic welding systems where equipment exists to facilitate this.

How Does MIG Pulse Welding Work?

Step on a combination of continuous wire feed with switch-controlled electrical pulses.

1. Wire Feeding

The wire feeder feeds welding wire through the welding torch all the time.

2. Shielding Gas Supply

A shielding gas is channeled through the torch to shield the weld from the atmosphere.

3. Arc Initiation

The wire nears the workpiece, and an electric arc is formed.

4. Peak Current Pulse

The machine applies a high-current pulse of varying duration that pulls the molten droplet from the wire.

5. Background Current

Current falls to a lower level, keeping the arc.

6. Controlled Droplet Transfer

The process is repeated at a specified frequency, melting wire and depositing metal into the weld pool.

7. Torch Movement

The operator or system automatically extends the torch to follow the joint.

8. Weld Formation

The transferred liquid metal mixes with the base material, and they form the welded joint.

9. Cooling and Solidification

The heat from the welding torch radiates away, causing the weld pool to solidify, thereby producing the completed weld.

What Is Double-Pulse MIG Welding?

Double-pulse MIG welding is a variation of pulsed MIG welding, wherein the welding current or wire-feed characteristics are modulated by an additional low-frequency pulse wave during the main pulse cycle.

This can result in a more controlled and visually interesting weld pattern in appropriate situations.

SR Advantech's MIG-P series a IGBT module inverter double-pulse MIG welder. It claims that this double-pulse can achieve the beauty weld, and its square-wave/pulse-width technology is designed to achieve stable control of welding.

Double-pulse systems can be particularly useful for:

• Aluminium welding
• Stainless-steel fabrication
• Visible welds
• Precision fabrication
• Heat-sensitive applications
• Tags where weld appearance is significant

But of course, final weld quality is determined by material, wire, shielding gas, joint design, torch travel speed, parameter set selected, and skill of the operator-not just the presence or absence of pulse.

Important Features to Look for in a MIG Pulse Welding Machine

Advanced Pulse Control

The key to reliable metal transfer is the ability to control the pulse current accurately and its timing.

Double-Pulse Function

A double-pulse function may prove useful for certain aluminum, stainless-steel, and appearance-sensitive applications.

Stable Wire Feeding

Continuous wire feeding is a must for a steady state of arc.

Accurate Voltage and Current Control

Independent control of welding parameters in a PSEE environment allows operators to adjust the parameters for various materials and thicknesses.

Digital Parameter Display

Digital controls may make installation easier and allow more consistency to be achieved during production.

Parameter Memory

The storage of welding parameters can also be advantageous when repeating production jobs. SR Advantech claims that its MIG-P machines can have a saving of up to 100 sets of customised parameter specifications.

Thermal Protection

Another less desirable option is to use either thermal protection to protect internal components against higher-than-rated temperatures or use forced airflow.

Input-Power Protection

Protection against low voltage, too high temperature, and surge of current is to protect the machine (which operating conditions are specified). The protection features below are listed by SR Advantech for the MIG-P series.

Suitable Wire-Feed System

The wire feeder should feed consistently and reliably for the diameter and material chosen.

Rugged Construction

Any industrial welding machine should be suitable for the working environment and production rate.

MIG Pulse Welding for Aluminium

Aluminium welding can be different from mild-steel welding due to the high thermal conductivity of the material, low melting temperature, and formed oxide layer that requires suitable process control.

Pulse MIG can have its advantages, as controlled metal transfer and heat input may aid the welding process.

Suitable equipment selection should consider:

• Aluminium wire
• Appropriate wire diameter
• Shielding gas
• Spool or wire-feeding arrangement
• Torch liner
• Contact tip
• Welding current
• Pulse parameters
• Travel speed
• Joint design
• Material thickness

SR Advantech has explicitly claimed that the MIG-P series is for the welding of aluminium, stainless steel and copper, with double-pulse technology targeted at aluminium welding.

MIG Pulse Welding for Stainless Steel

Welding of stainless steels needs to be carefully controlled for heat input and shielding conditions.

Pulse MIG can be a service to regulated metal transfer and can be suitable for some stainless steel fabrication processes.

Important considerations include:

• Stainless-steel wire selection
• Appropriate shielding gas
• Wire diameter
• Pulse settings
• Welding current
• Arc length
• Travel speed
• Joint configuration
• Heat input
• Surface preparation

It should always be set up using the applicable welding procedure and material specification.
