FAQs

What power supply does the Cros Arc Pulse MIG Multi Process 370C require, and is it suitable for UK workshops?
The 370C is a three‑phase machine, designed for 3P 400V ±15% 50/60Hz supplies. It draws around 20A input current at rated output, so it is suitable for most commercial UK workshops with a proper three‑phase distribution board. It is not intended for single‑phase or domestic supplies. If you are unsure about your incoming power, we can advise on suitability and any breaker/cable considerations before you buy.
What welding processes and materials can this machine handle?
It is a true multi‑process inverter covering MIG/MAG, pulse MIG, HD MIG/MAG, MMA and DC lift TIG. On MIG it supports mild steel, stainless, aluminium and flux‑cored wires in 0.6, 0.8, 1.0 and 1.2 mm diameters. That makes it suitable for bodyshop structural repairs, general fabrication, stainless work and light aluminium jobs. For TIG you will be limited to DC (no AC for ally), so it is mainly used for steels and stainless in TIG mode.
Is the 370C suitable for continuous professional use, and what is the duty cycle?
Yes, this is built as a workshop machine rather than a hobby unit. It has a 20–350A output range with a duty cycle of 350A at 60% at 40°C. In practice that means it will comfortably handle sustained welding on heavier sections without frequent thermal cut‑outs, provided the machine is installed with adequate ventilation. The air‑cooled configuration is appropriate for most steel and bodyshop work; for extreme high‑current production on thick aluminium a water‑cooled setup would be preferable.
What is included in the package and what else might I need to get started?
The standard package includes the 370C pulse inverter power source on a trolley, an M4 4‑metre MIG torch, earth return lead and clamp, and a gas hose. To start welding you will still need a suitable gas cylinder and regulator, wire, contact tips and shrouds, and a 400V three‑phase supply. Optional extras include a TIG kit (TIG torch and leads) and MMA leads if you plan to use it regularly in those modes. The machine uses a Euro‑type torch connection and standard consumables, which we can supply along with setup advice for your particular work mix.

Expert Advice

Paul Jones

Paul Jones says

This is a three‑phase, air‑cooled multi process MIG power source aimed at heavier bodyshop and workshop fabrication where you’re running solid or flux cored wire for longer periods. In practice I see it used on chassis repairs, jig work, thicker structural sections and light fabrication around the workshop, with pulse modes helping when you need cleaner welds and better control on thinner material transitions.

The key with this type of set is matching the process to the job: pulse or double pulse for controlled heat input and reduced spatter, standard MIG/MAG for straightforward structural welds. Make sure the air‑cooled torch rating is appropriate for your duty cycle – if you’re running higher currents for long runs, cable heating and consumable burn‑back become an issue.

A common problem is poor results caused by incorrect synergy selection or wire feed setup rather than a fault with the machine. Take time to dial in wire type, diameter and gas correctly. Used properly, this unit gives reliable, repeatable welds and good productivity for day‑to‑day professional work.
