TriPhase 400iS – 400 Amp Single Phase Welding Machine, Also Runs on 2 & 3 Phase

Overview

What is the TriPhase 400iS 400 amp single phase welding machine?

The TriPhase 400iS is a 400 amp single phase welding machine for stick (MMA) welding that also runs on a 415 V two-phase or three-phase line.

Many workshops and sites in India have only two lines of a 415 V supply, or a single-phase socket. Most 400 A welders need all three phases. This one gives the full 20–400 A on single phase, two phase or three phase, from the same machine. That makes it the most flexible 400 amp single phase welding machine in the Cruxweld range.

Inside is an IGBT inverter with a digital ammeter, Hot Start, adjustable Arc Force, anti-stick and a built-in voltage reduction device (VRD). Overload, over-voltage and thermal protection guard the machine on long shifts.

• One machine, any supplySingle phase, two phase or three phase, from the same input terminal.
• Full 400 A on every supplySingle, two or three phase: the full range for 5 mm electrodes.
• VRD for safetyLow voltage at the holder when the arc is off. Switch on the front panel.
• Digital ammeterSet the current on the display before you strike.

1. 1
   Digital ammeterShows the welding current in amps. Set the current before you strike and read it while you weld, so the same job gets the same setting every time.
2. 2
   230 V lampLights when the machine is running on a 230 V single-phase supply.
3. 3
   Thermal lampLights if overheating protection pauses the output on a very long run. Keep the machine switched on so the fan cools it; welding resumes by itself.
4. 4
   415 V lampLights when the machine is running on a 415 V two-phase or three-phase supply.

   Arc Force knob (1–10)Sets how hard the arc digs. Low for a soft arc on thin sheet; high for vertical, overhead and root runs. Stops the rod from sticking.
6. 6
   Welding Current knob (1–10)Sets the welding current from 20 A up to 400 A. Read the exact amps on the display as you turn it.

   Generator-ready markThe machine works on DG set power as well as the mains, for sites without a grid connection.
8. 8
   VRD ON / OFF switchON keeps the electrode holder at a low, safer voltage whenever you are not welding. Keep it ON for everyday work, especially in damp, confined or crowded areas.
