Description of the MIG 350 Welding Machine:

The MIG 350 welding machine with auto feeder sets the standard for professional MIG gas welding needs. It has strong control board features. Hence, there is a consistent and reliable performance in various situations.

In addition, this three-phase inverter ensures the stability of the output voltage when the input power supply fluctuates and the arc length changes. Furthermore, it has a self-adjusting ability which makes sure that there is a stable welding process for the entire workpiece.

Also, it has a strong pulse strike which provides consistency nad reliable arc-starts. Moreover, the auto-lock function reduces labor intensity on long welds.

Above all, this welding machine is lightweight, portable, and saves energy.

Additional Details of the MIG 350 Welding Machine:

  • Less splatter with high deposit efficiency
  • Lower distortion and strong weld formation
  • Strong pulse strike
  • Minimal molten ball if the arc is stopped mid-weld
  • Auto-lock function reduces labor intensity on long welds
  • Stable wire feeding with consistent output power
  • Lightweight and portable
  • Efficient
  • Suitable for a wide range of work environments

  • Main rectifier and inverter module have 3 years parts and labor
  • All ALLPRO welding machine, other electronic parts, and modules, wire feeders have 1-year parts and labor
  • Water coolers and tractors have 90 days parts
  • All ALLPRO welding gun, cable assemblies, and spool guns

Warranty Repair:

If ALLPRO confirms a defect, it will be fixed or replaced at their expense. Please return any parts that you have said are broken. These parts must be returned to either ALLPRO directly or its service facility. However, the customer is responsible for shipping to and from ALLPRO.

Warranty Limitations:

  • Will not accept repairs made outside of ALLPRO
  • Liability under this warranty shall not be more than the cost of fixing the defect of the ALLPRO product
  • Not liable for any damages (such as loss of business, etc.) caused by the defect or the time involved to fix the defect
  • Not responsible for the replacement of any part that is needed due to normal wear
  • Items manufactured by others (such as engines, engine components, air compressors, batteries, and accessories) are excluded

This written warranty is the only express warranty provided by ALLPRO with respect to its products.

This warranty gives the buyer specific legal rights. The buyer may also have other rights which vary from state to state.
