Heat in Tiny Doses. Thin Stainless Stays Flat and Bright.
The CRUXWELD IceFuse 250 is a 5-in-1 cold welding machine: a DC inverter that welds in short, timed bursts of 1–999 ms so thin sheet barely warms, then switches to HF TIG, Pulse TIG, MMA, and a cleaning mode that brightens the bead afterwards.

One Inverter for the Jobs That Punish Too Much Heat
Thin stainless, polished trim and finished parts do not forgive heat. A continuous arc warps the sheet, burns through the thinnest gauge and leaves a rainbow of heat tint that has to be ground and polished away.
The IceFuse 250 attacks that problem from two sides. Its cold mode welds in short, timed pulses with a pause between each one, so the heat never builds up. Its cleaning mode then lifts heat tint and oxide from the bead. Around those two sit a full HF TIG, Pulse TIG and MMA welder — five processes in one compact, dual-voltage machine.
Cold mode
Timed weld bursts with a set pause between them.
Clean mode
Brightens the bead after welding.
TIG + Pulse
HF or LIFT start, slopes, pulse up to 200 Hz.
MMA
1.6–4.0 mm electrodes with VRD.

02 · Why it stays cool
Heat in Tiny Doses Instead of a Steady Stream
A continuous arc keeps pouring energy into the joint, and on thin sheet that heat spreads, warps the panel and discolours the surface. In cold mode the IceFuse 250 fires a short weld burst of 1–999 ms, then pauses for up to 10 s before the next one. Each burst fuses a small spot; the pause lets the heat leave before the next.
What “cold welding” means here: low-heat fusion welding with a TIG arc — a true melted weld, delivered in small doses. It is not the solid-state pressure process of the same name.

From Heat Tint to Bright Metal on the Same Machine
1
Weld
Finish the joint in cold, TIG or pulse mode.
2
Switch to CLEAN
Select the cleaning mode and set 10–40 A.
3
Wipe the bead
Work the cleaning pen along the weld — about 2–3 cm² at a time.
4
Inspect
Heat tint and oxide lift away for a bright finish.
Less grinding and polishing after welding, and no second machine on the bench for cleaning.

PriceThe quotation changes with the torch and accessories you choose and with quantity. There is no process option to pay extra for — Cold, TIG, Pulse TIG, Clean and MMA are all in the one machine.
PowerSingle phase 220–240 V (or 110–120 V), 50/60 Hz, 7.1 kVA, maximum input current 38 A. Plan a socket and cabling rated for that 38 A input; no three-phase supply is needed.
LimitsTIG 5–200 A, Cold 5–220 A, MMA 20–180 A. For 415 V three-phase production welding above 200 A, look at the TIG welding machines range.

A welder that joins metal with very low heat input. In cold mode the CRUXWELD IceFuse 250 fires short weld bursts of 1–999 ms with a pause of up to 10 s between them, so thin sheet does not build up heat, warp or discolour.
Is it a real weld or solid-state cold welding?
It is a true fusion weld made with a TIG arc — just delivered in small, timed doses. It is not the solid-state pressure process that shares the name.
What are the five processes?
Cold welding, HF TIG (with a LIFT start option), Pulse TIG, Clean (weld-bead cleaning) and MMA stick welding.
What power supply does it need?
Single phase: 1 × 220–240 V or 1 × 110–120 V, 50/60 Hz, with a power capacity of 7.1 kVA and a maximum input current of 38 A.
Can it weld aluminium?
No. It is a DC machine for stainless, carbon and mild steel. For aluminium you need AC TIG, such as the CRUXWELD TIG 200 AC/DC.
What does the Clean mode do?
It uses a cleaning pen at 10–40 A to lift heat tint and oxide from the weld bead, giving a bright finish without a second machine.
Does it save gas?
Yes. Smart Gas matches gas pre- and post-flow to the set current, so you do not waste argon on long post-flow at low current.
