WELDING CAPABILITY

The Handymig 170i is rated at 130 amps, 20 volts, at 20% duty cycle on a ten minute basis. It is capable of higher output currents at lower duty cycles. .

LIMITATIONS

Arc Gouging cannot be performed with the Handymig 170i. The Handymig 170i is not recommended for pipe thawing or TIG welding.

CONTROLS AND SETTINGS

Refer to Figure B.1a.

1.Power ON/OFF Switch — When the power is on the fan motor will run and air will

be exhausted out the louvers

in the front of the machine. ON The welding output and wire

feeder remain off until the gun trigger is pressed.

FIGURE B.1a

2.Wire Speed Control — Controls the wire feed speed from 50 – 400 in/min (1.2 – 10.2 m/min). The control can be preset on the dial to the setting specified on the Handymig 170i Application Chart located on the inside of the wire feed section door.

3.Voltage Control — A 5-posi- tion tap selector switch gives full range adjustment of power source output voltage. Do not switch while welding.
