Two MIG welders from Hobart Welders — the Handler 135 and 175 — have a wide “sweet spot” so you won't waste time trying to get the right adjustment. The sweet spot is the point where the operator adjusts the wire feed speed and voltage to produce the classic “sizzling bacon” sound that signifies a good arc. A wire speed tracking function makes finding that spot easier. When the voltage knob is switched to a different tap for a different metal thickness or joint design, the function automatically increases or decreases the wire feed speed with the change in the voltage setting.
The Handler 135 ($459) can weld 22 gauge up to 3/16-in. steel. It plugs into 115v household current, weighs 55 lbs. and delivers 30- to 135-amp output. The Handler 175 ($669) can weld 22 gauge up to 3/16-in. steel or ¼-in. aluminum. It plugs into 230v current, weighs 65 lbs. and delivers 30 to 175 amps. Both machines handle mild steel, stainless, flux cored and aluminum wires. A dual-groove drive roll lets you change from .023/.025- to .030/.035-in.-dia. wire.
In addition to having an output capacitor to smooth the arc voltage, the Handler has a transformer and choke design that produces a softer, more desirable arc, according to the company. The Handler's control and feedback circuits respond quickly to changes in the arc.
