Lift up drive roll swing arms. Install PD inlet guide. Do not tighten set screw to secure inlet guide. Set screw may be used to secure PD inlet guide replacements such as wire straighteners or conduit adapters. Remove screw securing intermediate guide holder. (Guide holder is located between the lower front and rear drive roll carriers.) Rotate guide holder 180 degrees and reinstall. Install intermediate guide into guide holder and tighten set screw. Loosen set screw, insert exit guide into block near brass power pin gun connection and secure with set screw. When using smaller diameter inlet guide (219108) with non- PD (old style) drive rolls, a 1/4 in (6 mm) gap will be present between the guide and drive roll. 1 Tools Needed: 1/16, 1/8, 5/32 in 6 5 3 2 4 OM-228 956 Page 15 4-8. Installing Welding Gun 804 189-A 1 Power Clamp Knob 2 Gun Locking Tab 3 Power Pin Groove 4 Gun Connection End Installing gun with Accu-Mate connection Loosen power clamp knob to allow power pin of gun to clear the gun locking tab. When installing gun, the liner should extend into the PD continuous guide (or exit guide if used) as far as possible without interfering with the guide. Align the groove in the power pin of the gun with the gun locking tab. Secure gun by tightening power clamp knob. Installing gun without Accu- Mate connection When using a gun without the groove in the power pin, loosen power clamp knob and rotate gun locking tab 180 degrees. This prevents the locking tab from extending into the power pin gun connection. When installing gun, the liner should extend into the PD continuous guide (or exit guide if used) as far as possible without interfering with the guide. Secure gun by tightening power clamp knob. 3 Installing gun with Accu-Mate connection Installing gun without Accu-Mate connection 4 1 2 2 1 OM-228 956 Page 16 4-9. Installing Welding Wire And Adjusting Pressure Drive Setting Ref. 804 190-A Tools Needed: 1 Drive Roll Pressure Adjustment Lever 2 Notch In Lever (Indicates Pressure Settings) Pressure drive settings range from 1 to 8 with 8 being the maximum setting. For aluminum (soft) wire set pressure drive setting at 4 or below. Be sure that gun has proper size liner for the welding wire size. When installing gun, the liner should extend into the PD continuous guide (or exit guide if used) as far as possible without interfering with the guide. Install gun. Lay gun cable out straight. Cut off end of wire. Push wire through guide up to drive rolls; continue to hold wire. Press Jog button to feed wire out gun. To adjust drive roll pressure, hold nozzle about 2 in (51 mm) from nonconductive surface and press gun trigger to feed wire against surface. Adjust pressure drive lever so wire does not slip. Do not overtighten. If contact tip is completely blocked, wire should slip at the feeder (see pressure adjustment above.) Cut wire off. NONCONDUCTIVE SURFACE NONCONDUCTIVE SURFACE No Wire Slip Wire Slips Install wire spool. Adjust tension nut so wire is taut when wire feed stops. 15/16 in Drive Rolls End Of Liner Back Of Gun 1 Thread wire. Adjust tension. Pressure assembly door not shown. 2 OM-228 956 Page 17 4-10.

Operational Terms The following is a list of terms and their definitions as they apply to the interface unit in the wire feeder: General Terms: Arc Adjust Trigger Control DS (Dual Schedule) TH (Trigger Hold) 4T TDS (Trigger Dual Schedule) TPS (Trigger Program Schedule) Program Process MIG Pulse Accu-pulse RMD (optional) Wire Type Gas Type Process Set Up Program Load Volts Time Arc Length WFS Amps Arc Control Inductance Adjust Sequence Preflow Start Term used to represent arc length adjustments in pulse programs. Increasing Arc Adjust increases the actual arc length. Likewise, decreasing arc adjust shortens arc length. Arc Adjust is replaced by volts in MIG programs. Selecting Trigger Control allows activating trigger functions such as DS, TH, 4T, TDS, and TPS. Dual Schedule allows selecting a pair of programs that can be used together. Trigger Hold allows the operator to feed wire without continuously pressing the gun trigger. In trigger hold mode, momentarily press gun trigger, and wire will feed until gun trigger is momentarily pressed again. 4T allows the operator to select between weld parameters and crater parameters using the gun trigger. Crater time must be set for at least 0.2 seconds to make this function operational. If gun trigger is released during welding, unit goes into trigger hold, then pressing and holding trigger again causes unit to stay ...
