Best mig welder for 3/8 steel Buying guide
When selecting a MIG welder for 3/8 steel, you should consider the amperage range of the welder, the duty cycle, the type of wire feed, the type of power supply, and the type of shielding gas.
The amperage range should be sufficient to weld 3/8 steel depending on the thickness and type of material being welded. A welder that can produce up to 180 amps is recommended for welding 3/8 steel.
The duty cycle is the amount of time that the welder can be used continuously before it needs to cool down. A duty cycle of at least 20% is recommended for welding 3/8 steel.
The type of wire feed should be appropriate for welding 3/8 steel. It should be able to handle the type of wire and the size of wire being used.
The type of power supply should be compatible with the type of welding being done. Typically, a three-phase power supply is recommended for welding 3/8 steel.
The type of shielding gas should be appropriate for the type of welding being done. Argon/CO2 mix is recommended for welding 3/8 steel.
