PRODUCT DESCRIPTION

RECOMMENDED

PROCESSES AND 

EQUIPMENT

RECOMMENDED PROCESSES

The Power MIG® 21  is recommended for GMAW

 FCAW 

processes. The machine can support 4 inch and 8 inch spools of wire 

for GMAW and FCAW welding. The machine is intended for the 

following wire diameters and composition; Innershield NR-211

® 

.030 

- .045 self-shielding electrode and NR-212® .045 self shielding

electrode, .035 Outershield 71M FCAW-GS, SuperArc L-56 .025"

through .035" solid steel, .030 & .035" stainless MIG wires, and

SuperGlaze .030" through .035” aluminum.

PROCESS LIMITATIONS

Welding aluminum requires use of the Magnum® Pro 100SG Spool 

Gun. 

EQUIPMENT LIMITATIONS

The Power MIG® 21  is capable of MIG welding 

 amperes of 

current at 

 VDC, this output can be achieved at a 30% duty cycle 

based on a ten minute cycle time with the machine connected to 

230VAC input. The machine is capable of higher duty cycles at lower 

output currents or higher amperages at lower duty cycles. The machine 

can be connected to either 230VAC @60Hz or 120VAC @ 60Hz. The 

output of the machine is limited when the machine is connected to 

120VAC input, details regarding the rating when the machine is 

connected to 120VAC can be seen on the

rating plate.

Locate the welder in a dry location with free circulation of clean air into 

the back. A location that minimizes the amount of smoke and dirt 

drawn into the rear louvers, will reduces the probability of dirt 

accumulating and blocking air passages which can cause overheating.

SELECT SUITABLE LOCATION

Place the machine on a secure, level surface or recommended

undercarriage. The machine may topple over if this procedure is

not followed. To minimize over heating, locate the welder in a dry

location where there is free circulation of clean air. Do not place

on combustible surfaces.
