GENERAL DESCRIPTION

The PRO 100 is a compact lightweight DC wire feed- er/power source. It has been designed for workshop, hobby, and light maintenance. It is capable of general purpose welding with self-shielded flux-cored (Inner- shield®) wire. When combined with the optional K610- 1 MIG Conversion Kit, the PRO 100 is suitable for GMAW (MIG) welding applications.

The PRO 100 is ideally suited for individuals having access to 115 volt AC input power, and wanting the ease of use, quality and dependability of both the Innershield electrode process (self-shielded flux-cored or FCAW) and gas metal arc welding or GMAW (also known as MIG welding). The PRO 100 is a rugged and reliable machine that has been designed for dependable service and long life.

RECOMMENDED PROCESSES

The PRO 100 can be used for welding mild steel using the self shielded, Innershield electrode process (FCAW) or it can be used for the GMAW, single pass,

No external shielding gas is required when used with Lincoln Innershield .035” (0,9 mm) NR®-211- MP electrode.

Accommodates 4” (100 mm) diameter spool of wire. Will accommodate 8” (200 mm) diameter with optional spindle.

WELDING CAPABILITY

The PRO 100 is rated at 88 amps, 18 volts, at 20% duty cycle on a ten minute basis. CSA rated output at 62 amps at 20 volts at 20% duty cycle. It is capable of higher output currents at lower duty cycles.

LIMITATIONS

Arc Gouging cannot be performed with the PRO 100. The PRO 100 is not recommended for pipe thawing or TIG welding.

CONTROLS AND SETTINGS

process which requires a supply of shielding gas and the K610-1 MIG Conversion Kit. The PRO 100 is con- figured for use with the FCAW process as delivered from the factory.

OPERATIONAL FEATURES AND CONTROLS

The PRO 100 has the following controls as standard: Power ON/OFF Switch, Voltage Control, Wire Speed Control, Trigger Switch, and a Circuit Breaker.

DESIGN FEATURES AND

ADVANTAGES

Operates on 115 volt input .

“Cold electrode” until gun trigger is pressed for an

added measure of safety.

Overload protection — incorporates both a thermo-

stat and a circuit breaker.

Quality wire drive with electronic overload protec-

tion.

“Quick Release” idle roll pressure arm is easily

adjusted.

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. The welding output and wire feeder remain off until the gun trigger is pressed.

2.Wire Speed Control — Con- trols the wire feed speed from 50 – 300 in /min (1.3 – 7.6 m/min). The control can be preset on the dial to the setting specified on the PRO 100 Application Chart locat- ed on the inside of the wire feed section door.

3.Voltage Control — A 4-posi- tion tap selector switch gives full range adjustment of power source output voltage. Do not switch while welding.
