STAHLWERK ARC 200 MD review

A plain stick machine that becomes a DC TIG set when you add a torch — which is the cheapest route into TIG on this site.

Where we come out The cheapest honest path from stick welding into TIG, provided you accept lift start and a hand-operated gas tap.

A €100 stick inverter with a feature worth more than its price: with an optional WP-17V valve torch it becomes a DC TIG machine.

The upgrade path

A TIG torch with a gas tap in the handle needs nothing from the welder except steady direct current — no gas solenoid, no HF board, no timing electronics. So a plain stick inverter, plus a torch, plus a bottle and regulator, becomes a working TIG setup for steel and stainless.

What you give up is worth listing plainly: lift start instead of HF, so the tungsten touches the work each time; no pre-flow, so the first instant of the arc sees air; and manual post-flow, meaning you hold the torch over the cooling bead and close the tap by hand or watch the weld go black.

For occasional stainless brackets and tube work, that is a real capability at a fraction of the €300 an AC/DC machine costs. For regular TIG it is a stopgap, and this page says so rather than selling the idea harder than it deserves.

As a stick machine

Two hundred amps, IGBT on a single board. The single-board construction is worth a line: fewer inter-board connectors is fewer things to shake loose in a machine that gets carried around. No duty cycle is published, so read the current as a ceiling.

Sources

Current, processes, the optional torch and the construction come from the manufacturer’s published specification. Market availability was verified per market on the EAN; the reference was not live on the American store at the time of checking.

What it handles, and what it will not

Strengths

  • Becomes a DC TIG machine for the price of a valve torch, rather than a second welder
  • Single-board construction — fewer connections to fail than a multi-board build

Compromises

  • The TIG torch, the gas, the regulator and the tungstens are all extra
  • No published duty cycle
  • Lift start only on the TIG side, so no HF

The questions welders ask

How does a stick machine become a TIG machine?

With a valve torch. A WP-17V has a small gas tap in the handle, so it needs no gas solenoid inside the welder: you open the tap, strike by lifting the tungsten off the work, and close it after. The machine only has to supply steady direct current, which every stick inverter does. What you do not get is HF start, pre-flow or post-flow — those need electronics the machine does not have.

Is that a real TIG setup or a compromise?

A real one, with limits. It welds steel, stainless and copper properly. It does not weld aluminum, because that needs AC. And post-flow is manual — you hold the torch over the cooling weld and close the tap yourself, or the bead oxidizes. For occasional stainless work it is genuinely enough; for daily TIG it is not.
