3 Tips for choosing your inverter welder

Written by Paul V. last update of 11-10-2015


How to choose the welding machine

 1. Evaluate the level of "performance" you want

To choose the  inverter welder suited to your needs the first factor to consider is the use that you will have to do:

a - Hobby use

How to choose the welding machine

This product range includes all welding machines that have small power and low electrical absorption, designed for users  who do not require significant performance:

  • use purely in the home
  • DIY use
  • low purchase cost

You can make small metal constructions  like:

  • railings
  • andirons
  • tables
  • chairs
  • doors
  • small repairs

The average power is around  80-100 amperes. In the Telwin catalog, the Force series perfectly meets these characteristics. The Telwin Force 125 welding inverter has 1.6 to 2.5 mm electrodes.

b- Semi-professional use  

How to choose the welding machine?

Mid-range welders  are recommended for both novice and experienced users. They are designed for a

  • more continuous use over time
  • to weld even thick profiles
  • electrodes also of 3.2 mm
  • 2.5 mm electrodes for continuous welding without interruptions

Caution: These welding machines cannot be used continuously for 8 hours each day, despite having professional characteristics. 

c-Professional use

Inverter inverter welding machine: purchase guide

The professional inverter welder is designed for the most demanding users to carry out their work:

  • designed to give maximum power
  • low absorption in the electricity grid
  • continuous use 24 h
  • reliability over time 
  • special  Arc Force adjustment:  prevents electrode sticking
  • reduced maintenance

It is possible to weld:

  • heavy carpentry of various kinds
  • small carpentry
  • special metals, such as aluminum, stainless steel, and iron

Caution. The power of the welding machine is an essential component:

  • professional products start at around 125 Ampère
  • electrodes up to 4.0 mm can be used
The Deca inverter welder and the Telwin inverter welder represent an excellent solution for all types of users, from beginners to expert welders. The Telwin inverter welder also has an excellent price/quality ration which makes it much more convenient than a used inverter welding machine.

2. Evaluate the actual use over time  

Finally, you have managed to start welding but ...  the welding machine says enough!

How to choose the Telwin inverter welding machine

 

Nothing unusual happened: your welding machine was overheating and went into protection.

Each welding machine has a specific work cycle that is indicated on a plate placed on the machine or on a table shown in the instruction booklet.

Table-specific-welding

 WHAT DOES IT MEAN !!!!!!???

examples:

  • The first line identifies the diameter of the electrodes you intend to use (for example 2.5 mm)

  • The second line indicates the number of how many electrodes of this type you will use in 10 min (in our example 7,3 )

  • The third line indicated the actual welding time at your disposal compared to 10 min of the welding power (in our example  the  93% )

Table-specific-welding-partial

 summing up : 

 

  •  1st column: I can weld with an electrode from 1.6mm to 40 amperes for 10 minutes without the welding machine blocking, consuming 10.3 electrodes

  • 2nd column: I can weld with a 2.5mm to 55 Amp electrode for 10 minutes without the welding machine blocking, consuming 8.3 electrodes

  • 3rd column: I can weld with a 2.5mm to 80 Amp electrode for 9 minutes and twenty seconds (93% of 10 minutes), consuming 7.3 electrodes.

  • 4th column: I can weld with a 3.2 mm to 125 Ampere power electrode for 6 minutes, consuming almost 5 electrodes

 

The greater the power supplied and the diameter of the electrode used, the lower the utilization cycle will be. When the welding machine overheats it automatically locks to allow cooling.

Caution. While the welding machine cools it MUST NOT BE OFF!

 

 Concluding

How to choose the inverter welder according to the data plate

  • If you are a professional you have to choose a welding machine that can weld continuously without pauses and that can also use larger electrodes
  • If you need to use the welding machine in the home  for small repairs you can also buy  a welding machine with lower performance and shorter work cycle (over time that the welding machine cools you have any way to work on the piece, change the electrode and do all the other ancillary operations at work you are doing)

Choice of accessories

 

choose the price performance welding machine

Accessories are an important component while shopping:

  • electrode holder clamp

  • clamp for the mass

  • connection cables

  • mask   

It is better to buy the welding machine already complete with all the accessories

Welder + accessories kit

choose the kit welder

Buying the welding machine and accessories aside costs more.

summing up

 Buy inverter welders without accessories only if you already have accessories and a helmet mask.

 Choose to buy the inverter welders with case and accessory kit ready to weld immediately without further expenses. The Telwin catalog offers all the best solutions for your every need.
