inkl. MwSt.
Versand wird beim Checkout berechnet
A 200A 10-in-1 welder and plasma cutter that welds aluminum with Pulse MIG — built around 220V shop power, with the IPT-40 pilot-arc torch, HF TIG, and stick in one chassis.
One SD-4050 Pro replaces a MIG welder, a TIG welder, a stick welder, and a plasma cutter. It runs 220V input for full 200A output, with synergic MIG, flux core, HF TIG, stick, and 50A pilot-arc plasma cutting — IPT-40 torch and its wear-parts kit stocked in-store.
Five Processes. One Machine.
Every process below runs on the same 200A power source. Switch the torch, pick the mode, keep working.
Pulse MIG
200A · Aluminum
Graphite liner and aluminum tips feed soft wire cleanly. Welds aluminum-magnesium and aluminum-silicon sheet without a spool gun.
Flux Core
No gas tank
Self-shielded wire for outdoor and windy days. The go-to mode for fence, trailer, and farm repairs.
HF TIG
Thin & precise
High-frequency start for thin stainless, carbon steel, and copper. DC TIG precision on the same chassis. (AC TIG aluminum is the TIG-250AC's job.)
Stick
180A · Thick & rusty
Hot Start, Anti-Stick, and VRD make the stick arc forgiving on heavy, dirty stock.
Pilot Arc Cut
50A · IPT-40
Non-touch pilot arc starts through rust and paint. IPT-40 wear-parts kit always in stock.

Built for
- ✓220V shops & garages — UK/EU-style shop circuits run it at full 200A output.
- ✓Aluminum repair & fab — Pulse MIG with graphite liner and aluminum tips included.
- ✓Multi-process garages — MIG, TIG, stick, and cutting without three other machines.
- ✓Spool-gun aluminum — optional push-pull spool gun for extended aluminum work.
Not built for
- ✕110V-only outlets — the 2024 edition is a 220V machine; the 2026 edition adds 110/220V dual input.
- ✕Aluminum thicker than 1/4 in. — a dedicated AC/DC TIG is the right tool there. See the TIG-250AC.
- ✕Industrial production lines — duty cycle is prosumer grade, not 24/7 factory duty.
How It Compares
Same brand, three different jobs. Here is where the 2024 edition earns its price.

Frequently Asked Questions
Can it weld aluminum with Pulse MIG?
Yes. Pulse MIG mode (200A) feeds aluminum wire smoothly with the graphite liner and aluminum contact tips included in the box — no spool gun purchase required. Handles aluminum-magnesium and aluminum-silicon alloys.
What is the difference between the 2024 and 2026 editions?
Both are the same 10-in-1 200A platform. The 2024 edition runs 220V input with the IPT-40 pilot-arc plasma torch, aimed at UK/EU-style 220V shops. The 2026 edition adds 110V/220V dual input and the AG60 torch. Pick by your power supply and torch preference.
Can the HF TIG mode weld aluminum?
No — HF TIG here is DC TIG, made for thin stainless, carbon steel, and copper. Aluminum TIG requires AC output; that is the TIG-250AC's job. For aluminum on this machine, use Pulse MIG.
Does it support a spool gun?
Yes — the push-pull spool gun is supported as an optional accessory (sold separately, and available as a bundle variant). The included Pulse MIG setup already welds aluminum without it; the spool gun is for extended heavy aluminum work.
Which plasma consumables does it use?
IPT-40. SSimder stocks a 36-piece IPT-40 pilot-arc consumables kit (electrodes, tips, shields) matched to the included torch.
What warranty does it carry?
Every SSimder welder carries a 3-year warranty — the same policy across the line, spelled out on our warranty policy page.
