MillerMatic 180 MIG
From its manual .....
Amps Input : 21.7
Max. Recommended Circuit Breaker 25A
Min. Input Conductor 14ga (I used 10ga when I ran the new branch line)
The power cord that the plug is mounted on is 12ga.
Why did this welder come with a 50amp plug (NEMA 6-50P)? Instead of a 30A plug?
I wish to remove the power cord from the welder, and make a longer one myself with SOOW cord. But I would like to use a 30A plug (NEMA 6-30P), so I could use a 30A (6-30P) receptacle on the wall for other things than this welder.
I do not understand why I could not use the 30A plug. I do not understand why Miller used the 50A plug.
Is there something I don't understand amout HorsePower? When looking at the plugs in the Grainger's catalog .... besides amperage and voltage, they list HP for each plug. A 6-50 plug has a power rating of 3HP.. It seems that a 30A only has a power rating of 2HP. What is the Power Rating of my welder.
Thanks in advance for any info.
