Introduction

ThermalArc 202AC/DC TIG Welder

We have a ThermalArc 202 TIG welder unit that's a high-end TIG welding system capable of currents up to 200A (but currently limited to less, see status) which can weld Steel, Stainless Steel, Aluminum, Magnesium, Copper, Brass, Lead, and a variety of other metals as well as being capable of TIG Brazing and MMA (Stick) welding. As this is both one of the more expensive tools downstairs and one of the hardest to use induction is required before operating the TIG welder and it's recommended that people learn and practice using the MIG welder before moving on to TIG as MIG is substantially easier to learn and some of the skills will transfer. The TIG welder and it's argon gas bottle are normally kept under the metalworking table although at the moment we have another larger argon bottle on loan from Dean that's kept chained up by the back stairs. There is a charge for TIG welding of £10 per linear meter of weld produced.

Current Status

Date Status Comment
12th July 2019 Mostly Functional Limited to 90A in stick mode and 130A in TIG mode by the power connection.

The TIG welder has full envelope control on both AC and DC welding as well as HF-Start, Pulse-mode, Wave-Balance and Frequency control, which enables it to weld just about anything that's technically weldable. For simple jobs on mild steel it might be over-kill though and the MIG welder might be a better choice. For especially thick bits of metal it can be put into stick (MMA) mode where it can weld very thick materials quickly and cheaply although without the precision and neatness of the TIG process. If you're not sure of the best welding process for your job Steve's written a short guide that's here

The manual for the TIG welder is here.
