2 STEPS to choose the right welding machine for your application are:
1) Choosing the right welding process
2) Understanding Input and Output Power requirements and machine size for your needs.
There are various types of welding processes, each having its own advantages and disadvantages. The most common welding process are Shielded Metal Arc Welding (MMAW / Stick Electrode Welding), Gas Tungsten Arc Welding (TIG / GTAW), Gas Metal Arc Welding (MIG / MAG / GMAW).
Points to note while selecting a machine:
Following is the ready reference chart while selecting a process between SMAW (Arc/Stick Welding), GTAW (Tig Welding) and GMAW (Mig Welding) welding process types:
TWO important points related to input power to be check while selecting a welding machine.
1) Check the Input Power Rating of the machine. This is specified as Input KVA and also as Max Power Installed in HP. Input KVA is mentioned for two output currents as per rating of the machine. If the output used in practical application is lesser, then the input power consumed by the machine also will be lower. If you are planning to use the machine on a generator power, make sure you have the generator rating at least 1.5 times the Max power installed for safe and continuous operation.
2) Check the type of Phase and Supply Voltage Rating of the machine. Some machines are rated for Single Phase and some from Three Phase. Single Phase is generally used in Residential or low industrial areas. Three Phase supply is generally available in industrial areas only. Also check what is input voltage supply rating. For example, some machine are rate for 415VAC input. The range of input supply is also mentioned in the specification sheet. For example, out model Magnus 400CCCV is rate for 350VAC to 500VAC input voltage. If your line supply rating falls in this rage you are good to go.
Duty Cycle of a machine denotes how long can be a machine used continuously at what output current and voltage. This is as a standard denoted using a 10 minute cycle as a constant. For example if we say a machine is 60% duty cycle at 250Amp 28Volt means that it can run for 6 minutes at 250 Amp 28 Volt before it need 4 minutes to cooled down to be used again. When checking out product specifications, it is important to note both Current and Voltage for a rated duty cycle.
Light Industrial or DIY kind of machines are rated for 20% to 50% Duty Cycle.
Medium Industrial machines are rated for 40% to 60% Duty Cycle.
Heavy Industrial machines are rated for 60% to 100% Duty Cycle.
SIZE AND PORTABILITY
Check if your machine is as per the size / dimensions you expect it for carrying the same. Check if it has handles or eyebolts for lifting. One more point to check while buying a machine is if it has wheels for moving around in your workshop or does it have rubber footing and can be moved only by lifting. These details are mentioned in Mechanical Specifications section for each machine.
