INSTALLATION

Fuse the input circuit with the recommended super lag fuses or delay type1 circuit breakers. Choose an input and grounding wire size according to local or national codes or refer to the Technical Specifications page at the beginning of this section. Using fuses or circuit breakers smaller than recommended may result in “nuisance” tripping from welder inrush currents even if not welding at high currents.

Unbalanced AC TIG welding draws higher input cur- rents than those for Stick, DC TIG, or Balanced AC TIG welding. The welder is designed for these higher input currents. However, where unbalanced AC TIG welding above 180 amps is planned, the higher input currents require larger input wire sizes and fuses per the Technical Specifications page at the beginning of this section.

1Also called “inverse time” or “thermal/magnetic” circuit breakers, circuit breakers which have a delay in tripping action that decreases as the magni- tude of the current increases.

INPUT RECONNECT PROCEDURE

On multiple input voltage welders, be sure the recon- nect panel is connected per the following instructions- for the voltage being supplied to the welder.

Designations on the reconnect panel, LOW, MID, and HIGH correspond to the nameplated input voltages of a triple voltage welder. Dual voltage welders use only LOW and HIGH.

EXAMPLE: On a 208/230/460 volt welder, LOW is 208V, MID is 230V, and HIGH is 460V.

Make sure all connections are tight. Replace the case side and all screws.

SINGLE PHASE INPUT POWER SUPPLY CONNECTION INSTRUCTIONS:

WARNING: Powered by high voltage which can kill. Turn off all input power at the disconnect switch or fuse box before making any connections. Use

input and grounding lead sizes as specified in the operating manual. Failure to follow instructions below can cause immediate failure of components within the welder.

1.Connect the input power leads to the input terminals, L1 (U) and L2 (V), at the right below. Connect the input power leads with the hardware provided. Completely tighten all fasteners.

2.Connect a grounding lead to the ground stud located on the machine base near the input terminals.

3.Welders are shipped connected for the highest rated single phase input voltage with the lead marked "A" connected to the stud marked "4 (HIGH)".

4.For middle range input, reconnect the lead marked "A" to the stud marked "3 (MID)".

5.For low range input, reconnect the lead marked "A" to the stud marked "2 (LOW)".
