Component Identification and Explanation
INNOTEC 36 Series MIG Torch Parts Breakdown
Over time, pressure on the drive rolls causes metal fragments from the filler wire's surface to find its way to the gun cable liner. If the wire guide is not cleaned, it can gradually clog up and causes wire
feed malfunctions. Other factors control smooth wire feeding as well. Wires that are .023" to .030" (.6mm to . 8mm) require a liner change from stock size of the gun to prevent wire balling/bird's nesting
at the feeder. The .023" diameter wire should not be used in a gun over 10ft (3m). The .030" wire diameter should not be used in a gun over 12.5 feet (4m) Purchase of an optional liner and possibly a
smaller series gun such as the 15 or 24 series, which are available from Everlast, is recommended for use with these smaller sizes for best performance.
NOTICE:
If feeding difficulty is observed, first confirm that the liner is the proper size and torch is proper length for your wire diameter, then:
1.
Remove the welding gun's gas nozzle, contact tip and contact tip's adapter.
2.
With an air nozzle blow compressed air through the wire guide. Wear eye protection!
3.
Blow out the wire feed mechanism and reel housing with dry compressed air.
4.
Reassemble components. Tighten the contact tip and contact tip's adapter with the spanner included to ensure tightness. Do not overtighten any fittings or stripping of the threads may result.
The MIG torch liner may eventually become worn and will need to be replaced. When welding aluminum with the main gun, a Teflon liner must be used, necessitating a liner change. A spool gun is the
preferred method to weld Aluminum, but a polymer liner may be used with guns10ft.and under to weld aluminum. In this case, you will need to change the standard liner intended for steel use to feed
directly from the machine and use U groove drive rolls to prevent deformation to the wire.
To change the liner:
1.
Remove the nozzle and the securing compression nut of the liner (#17) to expose the brass fitting end of the liner (if a polymer liner is already installed it will be a brass ferule and o-ring) .
2.
Straighten the gun cable and withdraw the liner slowly from the gun. If the liner refuses to be withdrawn easily, this could indicate severe liner damage or gun cable damage.
3.
Carefully push a new wire guide in to the gun. Make sure that the wire guide travels all the way to the contact tip without interference with tip. Remove Contact tip once installed.
4.
For Polymer liners, make sure the O-ring and brass ferule at the machine-end of the gun are installed. For steel liners make sure the fitting is flush and the O-ring is in place.
5.
Tighten the liner in place without over tightening, especially with the polymer liner.
6.
For polymer liners cut the line 1 to 2 mm from the rear compression nut (at the Euro quick connect fitting) and file the sharp edge of the liner. For steel liners, no trimming is required unless
liner is sticking out gun handle too far. If the liner is passing the point where the contact tip screws in and seats, remove and trim the liner with a pair of side cutters or similar tool and file any
sharp edges before reinserting the liner.
7.
Reattach the gun and tighten all parts.
8.
Re-thread wire through the feeder and gun, leaving contact tip off until wire feeds completely through the gun. Once the wire feeds through install contact tip and nozzle.
