What it welds
The HONETOOL MMA140D Stick Welder is a stick inverter with a maker-stated output of up to 120 amps on 110-volt input.
At its top output of 120 amps, Miller's 1-amp-per-thousandth rule points to about 0.120 in of steel per pass. Where the rule comes from.
The listing doesn't give a duty cycle with its amperage, which makes long beads hard to plan; the rating plate or manual should state it. Why it matters.
Electrodes, per the maker: 1/16"-1/8". Each rod's packaging states its current range; OSHA ties 60 to 160 amps to 3/32 to 5/32-inch rods and a minimum shade 8.
Household 120-volt power caps its output; check the circuit size the manual asks for. What input voltage changes.
Use a lens of at least OSHA's minimum shade for the current: shade 8 or darker for typical TIG or stick work here. Shade chart.
Also on the listing: dimensions of 9 x 3.9 x 5.6 inches and a weight of 9.44 lb.
