Unlock your full potential with the new Maxstar 400 advanced DC TIG welder. Now equipped with an intuitive LCD interface that puts precision welding capabilities at your fingertips.

Features

An improved working environment is created during welding. Welders are not exposed to open flame, explosive gases and hot elements associated with fuel gas heating and resistance heating.
Easy setup is achieved using flexible heating cables combined with user-friendly insulation blankets.
On-board temperature control provides for manual or temperature-based programming in a simple-to-learn operator interface.
Uniform heating is maintained along and through the heat zone by using induction heat within the material. The surface of the part is not marred by localised conducted heat at higher than specified temperatures.
Time-to-temperature is faster than conventional processes Due to the method of applying heat, the cycle time is reduced.

415v TIG Welders FAQs

Straight answers to the questions people ask most when choosing and using three phase TIG welders.

What is the supply requirement?

A three phase machine needs a suitable three phase supply with the correct voltage and protection. The data plate and manual specify the voltage range, input current and fuse or breaker size. Many machines accept a range of three phase voltages.

Have the installation, cable and isolator fitted and checked by a competent electrician. Do not use adaptors or improvised connections, and make sure the supply capacity suits the full welding output.

How do I choose the output rating?

Consider the thickest material and the metal. Aluminium needs more current than steel for the same thickness. Choose a machine with a maximum current comfortably above what you will need regularly, since this gives a better duty cycle, a cooler running machine and headroom for heavier jobs.

Also consider the lowest current. A machine with a low, stable minimum current suits thin material and precise work. A wide range between minimum and maximum makes the machine more versatile.

What does duty cycle mean?

Duty cycle is the proportion of a ten minute period that a machine can weld at a given current without overheating. A figure of 60 percent means six minutes welding and four minutes cooling. It falls as current rises.

For continuous production welding, choose a machine whose duty cycle at your working current is high. Industrial three phase machines are generally built to a higher duty cycle than lighter single phase ones. Check the rating at the current you will actually use.

AC/DC or DC only: which do I need?

A DC machine welds steel, stainless steel, copper and many other metals, but not aluminium or magnesium. An AC/DC machine adds AC output, which cleans the oxide layer on aluminium and magnesium so they can be welded properly.

If you will ever weld aluminium, choose AC/DC. Look for adjustable AC balance and frequency, which let you tune the cleaning action and the arc focus.
