OPTIONS/ACCESSORIES

The following options/accessories are available for your Square Wave TIG 355 from your local Lincoln Electric Distributor.

Undercarriage (K841) – Includes a platform, wheels, and brackets for supporting the welder and two gas cylinders.

Pump Mounting Platform (K827) – Mounts on top of the welder to provide a mounting surface suitable for water recirculating pumps.

Arc Start Switch (K814) – Starts the welding sequence if remote control for TIG welding is not desired. Plugs into the Remote Receptacle. The Current Control switch must be in the LOCAL position when using the Arc Start switch; only a minimum cur- rent (2 amp) is available in REMOTE. Includes 25 ft. (7.6 m) cable.

Interface Kit (K846) – Mounts to the back of the LED status PC board. Provides six isolated circuits that can be closed to provide status indication when each of the following functions is active: High Frequency, Arc Established, Start, Pulse Peak, Pulse Background, and Crater Fill. Each circuit occupies two positions on a terminal strip and consists of a fuse, fuse holder, and sockets for an industry standard, optically isolated Solid State Relay (SSR) module (purchased separate- ly, see below).

Solid State Relays (SSRs):

K847-DC– Can switch up to 40VDC, 2 amps maximum load. Package of two.

K847-AC– Can switch up to 130VAC, 2 amp maximum load. Package of two.

Amptrol™ (K870 or K963) – Provides a remote cur- rent control for most TIG welding applications. Model K870 is a foot operated control; model 812 is hand operated. Both models plug into the remote control receptacle. A separate switch on the Amptrol starts the welding sequence. When the Current Control switch on the welder is set in the LOCAL position, the Amptrol works as an arc start switch only; it does not control current. (Current is controlled by the rheostat on the front panel.) When the Current Control switch on the welder is set to the REMOTE position, current is controlled by the Amptrol, in a range from 2 amps up to the current set on the control panel. For a more detailed explanation of Amptrol operation, see the Operation Section of this manual.

1Use of the Synergic 7 wire feeder requires appropriate input cable assembly, wire stand, and drive roll kit. Refer to Synergic 7 Operator’s Manual for available options.
